This patch centralizes the definition for surface pressure, oxygen in
air, (re)defines all such values as plain integers and adapts calculations.
It eliminates 11 (!) occurrences of definitions for surface pressure and
also a few for oxygen in air.
It also rewrites the calculation for EAD, END and EADD using the new
definitons, harmonizing it for OC and CC and fixes a bug for EADD OC
calculation.
And finally it removes the unneeded variable entry_ead in gtk-gui.c.

Previously we calculate the ceiling at every single second, using the
interpolated depth but then only *save* the ceiling at the points where we
have a profile event (the whole deco_allowed_depth() function doesn't
change any state, so we can just drop it entirely at points that we aren't
going to save)
Why is it incorrect? I'll try to walk through my understanding of it, by
switching things around a bit.
- the whole "minimum tissue tolerance" thing could equally well be
rewritten to be about "maximum ceiling". And that's easier to think
about (since it's what we actually show), so let's do that.
- so turning "min_pressure" into "max_ceiling", doing the whole
comparison inside the loop means is that we are calculating the
maximum ceiling value for the duration of the last sample. And then
instead of visualizing the ceiling AT THE TIME OF MAXIMUM CEILING, we
visualize that maximal ceiling value AT THE TIME OF THE SAMPLE.
End result: we visualize the ceiling at the wrong time. We visualize
what was *a* ceiling somewhere in between that sample and the previous
one, but we then assign that value to the time of the sample itself.
So it ends up having random odd effects.
And that also explains why you only see the effect during the ascent.
During the descent, the max ceiling will be at the end of our
linearization of the sampling, which is - surprise surprise - the position
of the sample itself. So we end up seeing the right ceiling at the right
time while descending. So the visualization matches the math.
But during desaturation, the maximum ceiling is not at the end of the
sample period, it's at the beginning. So the whole "max ceiling" thing has
basically turned what should be a smooth graph into something that
approaches being a step-wise graph at each sample. Ergo: a ripple.
And doing the "max_ceiling during the sample interval" thing may sound
like the safe thing to do, but the thing is, that really *is* a false
sense of safety. The ceiling value is *not* what we compute. The ceiling
value is just a visualization of what we computed. Playing games with it
can only make the visualization of the real data worse, not better.

Previously we would simply show the first dive in the divelist - which
worked fine in the default sort by trip setting and assuming that there
are no dives from the future in the divelist.
With this commit we actually find the correct dive in the divelist and
select it instead. If you sort by depth you will see the dive move around
in the divelist, but it will stay selected and visible in the profile.

Previously the code in init_decompression() would mindlessly walk back the
dive_table until it found a gap of at least 48h and take all those dives
into consideration when calculating tissue saturation. This goes horribly
wrong if you load dives from two divers into the same data file.
With this commit things will still turn out correctly, as long as the
dives are in separate trips in for each of the divers. So with this I can
load both Linus' and my divelog and things stay sane even on our shared
dive trips.

- MOD: Maximum Operation Depth based on a configurable limit
- EAD: Equivalent Air Depth considering N2 and (!) O2 narcotic
- END: Equivalent Nitrogen (Narcotic) Depth considering just N2 narcotic
(ignoring O2)
- EADD: Equivalent Air Density Depth
Please note that some people and even diving organisations have opposite
definitions for EAD and END. Considering A stands for Air, lets choose the
above. And considering N for Nitrogen it also fits in this scheme.
This patch moves N2_IN_AIR from deco.c to dive.h as this is already used
in several places and might be useful for future use also. It also
respecifies N2_IN_AIR to a more correct value of 78,084%, the former one
also included all other gases than oxygen appearing in air. If someone
needs to use the former value it would be more correct to use 1-O2_IN_AIR
instead.

Testing the new "don't even bother saving default values" showed that the
default values for the deco gradient factors were undefined.
Or rather, they were over-defined.
We had defaults for the UI (30 and 75 for GFlow/GFhigh respectively - the
config ones are in percent), *and* we had defaults in deco.c for the deco
code itself (0.35 and 0.75 respectively - in deco.c they are represented
as fractions, not percent).
And if the config entries had never been written, and were assumed to be
the defaults, the UI code thought the defaults were 30/75, but they had
never been *set* to those defaults, so actual default calculations
silently used the 35/75 in deco.c, which is very confusing (you could go
to the preferences page, see the 30/75 there, and it would not actually
match th evalues used for computation).
Of course, with an old config file that saves even default entries, you'd
never see that if you ever changed anything in the preferences, because
you'd always have explicit gflow/high values. But now it's much easier to
see the conflicting default values.
Fix it by just always using the UI defaults (or set values) to set the
actual deco values.

The old code (on purpose) didn't try to differentiate "nonexisting
boolean configuration" with "existing boolean configuration set to
false", which is problematic if we optimize the saving to not save
default preferences at all.
Which this does.
So in addition to the logic to know about default preferences, this has
to change the interfaces for the PREF_BOOL reading code so that you can
tell the difference between "no value" and "false".
And since the previous calling convention was an abomination of doing
pointer casting and having case-statements for the config types, change
that while at it. Both from a usage perspective *and* from a back-end
perspective it is actually much simpler to just have different functions
for the string vs boolean config read/write versions. The OSX versions
in particular end up being one-liners.
(The GConf library is a nightmare, and doesn't seem to have any way to
know whether a boolean value exists or not, so you have to read it as a
GConfVal and then turn it into a gboolean rather than just get the "oh,
it didn't exist" as an error value).

This makes it explicit what the default preferences are, so that we can
more easily avoid unnecessarily saving default settings. It also makes
imperial metrics the default for the US (Burma and Liberia always get
forgotten!)
Right now we tend to be somewhat confused about defaults. We do have
them, but then even if something has a default value, we tend to write
it out to the config file. Which is not just unnecessary, but makes it
really hard to see after-the-fact whether the user actually wanted that
*specific* value, or whether they just wanted the default behavior.
So this prepares for having explicit configuration for when we want
something different than the defaults.

.. and rename the badly named 'output_units/input_units' variables.
We used to have this confusing thing where we had two different units
(input vs output) that *look* like they are mirror images, but in fact
"output_units" was the user units, and "input_units" are the XML parsing
units.
So this renames them to be clearer. "output_units" is now just "units"
(it's the units a user would ever see), and "input_units" is now
"xml_parsing_units" and set by the XML file parsers to reflect the units
of the parsed file.

This moves the point where GF_low applies up which implies that at all
shallower depth (i.e. during deco) a lower GF results which makes the deco
longer compared to the previous implementation.
Of course, "GF_low" applies at first deco stop is a bit tricky since the
depth of the first deco stop again depends on GF_low, i.e. there is
another equation to solve. You can do this by inverting the equation for
the ambient pressure and use GF_low as the gradient factor. This yields
amb = (b * M_value_corrected - GF_low * a * b) / ((1-b) * GF_low + b)

It turns out that the serial number returned by libdivecomputer isn't
really the serial number as interpreted by the vendor. Those tend to be
strings, but libdivecomputer gives us a 32bit number.
Some experimenting showed that for the Suunto devies tested the serial
number is encoded in that 32bit number:
It so happens that the Suunto serial number strings are strings that have
all numbers, but they aren't *one* number. They are four bytes
representing two numbers each, and the "23500027" string is actually the
four bytes 23 50 00 27 (0x17 0x32 0x00 0x1b). And libdivecomputer has
incorrectly parsed those four bytes as one number, not as the encoded
serial number string it is. So the value 389152795 is actually hex
0x1732001b, which is 0x17 0x32 0x00 0x1b, which is - 23 50 00 27.
This should be done by libdivecomputer, but hey, in the meantime this at
least shows the concept. And helps test the XML save/restore code.
It depends on the two patches that create the whole "device.c"
infrastructure, of course. With this, my dive file ends up having the
settings section look like this:
<divecomputerid model='Suunto Vyper Air' deviceid='d4629110'
serial='01201094' firmware='1.1.22'/>
<divecomputerid model='Suunto HelO2' deviceid='995dd566'
serial='23500027' firmware='1.0.4'/>
where the format of the firmware version is something I guessed at,
but it was the obvious choice (again, it's byte-based, I'm ignoring
the high byte that is zero for both of my Suuntos).

The legacy nickname wrappers (that use the device_info structure) are
left in gtk-gui.c. We can slowly start moving away from them, we don't
want to start exporting that thing as some kind of generic interface.
This isn't a pure code movement - because we leave the legacy interfaces
alone, there are a few new interfaces in device.c (like "create a new
device_info entry") that were embedded into the legacy "create nickname"
code, and needed to be abstracted out.

We have several places where we interpolate the depth based on two
samples and the time between them. Some of them use floating point, some
of them don't, some of them meant to do it but didn't.
Just use a common helper function for it. I seriously doubt the floating
point here really matters, since doing it in integers is not going to
overflow unless we're interpolating between two samples that are hours
apart at hundreds of meters of depth, but hey, it gives that rounding to
the nearest millimeter. Which I'm sure matters.
Anyway, we can probably just get rid of the rounding and the floating
point math, but it won't really hurt either, so at least do it
consistently.
The interpolation could be for other things than just depth, but we
probably don't have anything else we'd want to interpolate. But make the
function naming generic just in case.

This change ended up being quite a bit bigger than expected as it
uncovered a number of bugs in the existing code.
The planner now handles gas changes correctly by creating (and later
parsing) events in the simulated divecomputer. At the end of the dive
specified in the input form the algorithm starts with the deepest
interesting depth: either the first stop below our ceiling or the deepest
depth at which we can change gases. It then traverses all the stop and all
the gas change depth and at each stage ensures that we are allowed to
ascend further before going on.

An entry with no time is considered special and not considered when
constructing the profile.
This should allow us to add support for two different ways of adding
information about available gas:
changedepth 0 gasmix
0 0 gasmix @ po2
The first syntax basically says "during the ascent, switch to this gas at
this depth.
The second one says "switch to this gas once the pO2 allows for it"
Neither of these are implemented, yet, but this commit is necessary in
order for the rest of the code to ignore entries with a time field of 0.

This commit makes sure we have a reasonable default surface pressure (we
need an input field for that).
It also adjusts the debug level settings so that compiling this with
make CLCFLAGS=-DDEBUG_PLAN=3
will print out an almost usable dive plan.
This is of course still lacking air consumption calculations and will show
deco stops that we just transit through (if the ceiling lifts far enough
during the transition to an intended stop that this stop can be skipped;
this sometimes happens for the first stop (haven't seen it for a later
one). But it's better than nothing, I guess.

The existing code incorrectly started all calculation at the depth at the
end of the first segment. So if you went to 50m in 5min in your first
segment, you incorrectly got 5 minutes at 50m (instead of a progression
from 0 to 50m, over 5 minutes).
This commit fixes that and now gives us planned dives that then match what
is shown in the profile.

This shouldn't change the the actual stops we do or the travel time how we
get there, but it makes the code more logical. From the end depth of the
planned dive we have ONE transition to the first stop depth (which may be
the surface). And then for every stop we (potentially) have a wait and
travel to the next stop.
Once we are in the while loop, we know that we are at a stop level, so
there is no point to keep checking if we first need to transition to the
stop.
It does create one additional improvement: if we don't need any stops at
all, then we don't transition to the first stop and then from there to the
surface. We do it in one step. The overall profile / traveltime remains
the same, we just drop one intermediate sample on the way.
This also improves a few ugly (and in one case, wrong) debug statements.

In commit a7902f279a57 "Rewrite of the deco code" Robert kept the old code
that he replaced around; I removed all that as it's in the git history if
we ever need to look at it again but doesn't really help us in the file as
it is.
I also removed constants, variables and config parameters that aren't used
in the new implementation and did some coding style / formatting changes
to make deco.c more consistent with the rest of Subsurface. I also updated
the comments at the top of the file to reflect reality.
I did one change that actually affects the code. In the explanation of his
changes Robert said that gf_low_pressure_this_dive is initialized to the
exquivalent of 20m, yet his code added the surface pressure twice. I
decided to change the default config value from 3 (bar) to 2 so that this
indeed reflects (about) 20m (as in the code below surface_pressure is
added to this value).

o) Instead of using gradient factors as means of comparison, I now use
pressure (as in: maximal ambient pressure).
o) tissue_tolerance_calc() now computes the maximal ambient pressure now
respecting gradient factors. For this, it needs to know about the
surface pressure (as refernce for GF_high), thus gets *dive as an
argument. It is called from add_segment() which this also needs *dive
as an additional argument.
o) This implies deco_allowed_depth is now mainly a ambient-pressure to
depth conversion with decorations to avoid negative depth (i.e. no deco
obliation), implementation of quantization (!smooth => multiples of 3m)
and explicit setting of last deco depth (e.g. 6m for O2 deco).
o) gf_low_pressure_this_dive (slight change of name), the max depth in
pressure units is updated in add_segment. I set the minimal value in
buehlmann_config to the equivalent of 20m as otherwise good values of
GF_low add a lot of deco to shallow dives which do not need deep stops
in the first place.
o) The bogus loop is gone as well as actual_gradient_limit() and
gradient_factor_calculation() and large parts of deco_allowed_depth()
although I did not delete the code but put it in comments.
o) The meat is in the formula in lines 147-154 of deco.c. Here is the
rationale:
Without gradient factors, the M-value (i.e the maximal tissue pressure)
at a given depth is given by ambient_pressure / buehlmann_b + a.
According to "Clearing Up The Confusion About "Deep Stops" by Erik C.
Baker (as found via google) the effect of the gradient factors is no
replace this by a reduced affine relation (i.e. another line) such that
at the surface the difference between M-value and ambient pressure is
reduced by a factor GF_high and at the maximal depth by a factor
GF_low.
That is, we are looking for parameters alpha and beta such that
alpha surface + beta = surface + gf_high * (surface/b + a - surface)
and
alpha max_p + beta = max_p + gf_low * (max_p/b + a - max_p)
This can be solved for alpha and beta and then inverted to obtain the
max ambient pressure given tissue loadings. The result is the above
mentioned formula.

The dive will start with gas 0. If things change during the planned part
of the dive, this will be represented by an event. Use the last gas for
the ascent.
Obviously this still doesn't handle deco gases, but at least we now no
longer switch back to the first gas after the planned part of the dive.
This also adds quite a bit of debugging code to be able to trace what's
happening in the planner.

Stupid Gtk. Seriously. So in order to get a notification if the user
selects the drop down for the gas with the mouse I need to connect to the
"changed" signal for the combobox. But that also fires whenever the user
types something into the GtkEntry. Which means we once again get called
for all kinds of silly partial names.
Instead we want to handle the manual entry in the "focus-out" callback
(the user has hit tab or something else to move away from the GtkEntry -
let's assume that this is the text he wants us to use) and only respond to
the changed signal on the combobox if the user selected something from the
dropdown.
The easiest way to do that (I think) is to check the text with the strings
stored in the model. If this indeed matches a string stored in the model
then most likely this is something the user selected from the dropdown.
But more importantly if it isn't in the model, then we KNOW that this is
just a partial string that was typed in. And we can ignore that one.

- Correct bad translations (correct with *0.90 scaling).

With this a partially planned dive is indeed thrown away when hitting
Cancel.

This simplifies the dive planning code by:
- allowing empty gas mixes (which means "pick previous gas")
- avoiding unnecessary strdup/free calls (this requires us to handle
"const char *" in the parsers, but that was already true from a code
standpoint, just not a type one)
- re-use the "plan()" function for a successful dive plan, rather than
open-coding the dive plan segment handling.

This appears to happen if we have impossible dive sequences in the
dive_list (i.e., merging XML files from two different divers with
overlapping trips).
We need to fix the underlying cause for this issue (i.e., only pick the
'right' dives to calculate the residual tissue saturation), but at least
this code prevents the hang in an infinite loop.

First, I forgot to pass in the idx into the gas callback function - this
way for the dynamically created dives we always used air for anything but
the first segment.
Second, when selecting a gas from the drop down (with the mouse or by
typing), the GtkEntry doesn't receive that text and therfore we never
picked up those gases.
We now also track the 'changed' event for the GtkComboBox, but never add
the text we get their to the completions (as by definition they are
already there).

There should be NO other changes in this commit - just moving the code and
adjusting the includes (and adding the entry point to display-gtk.h).
