This adds watertemp and airtemp to the dive, populates them in fixup and
uses them elsewhere in the code.
WARNING: as a sideeffect we now edit the airtemp in the dive, but we never
display this in the DIve Info notebook (as that always displays the data
from the specific selected divecomputer). This is likely to cause
confusion. It's consistent behavior, but... odd. This brings back the
desire to have a view of "best data available" for a dive, in addition to
the "per divecomputer" view. This would also allow us to consolidate the
different pressure graphs we may be getting from different divecomputers
(consider the case where you dive with multiple air integrated computers
that are connected to different tanks - now we could have one profile with
all the correct tank pressure plots overlayed - and the best available (or
edited) data in the corresponding Dive Info notebook.
This commit also fixes a few remaining accesses to the first divecomputer
that fell through the cracks earlier and does a couple of other related
cleanups.

When starting on this quest to stop using the first divecomputer instead
of data for the whole dive in commit eb73b5a528c8 ("Duration of a dive is
the maximum duration from all divecomputers") I introduced an accessor
function that calculates the dive duration on the fly as the maximum of
the durations in the divecomputers.
Since then Linus and I have added quite a few of the variables back to the
dive data structure and it makes perfect sense to do the same thing for
the duration as well and simply do the calculation once during fixup.
This commit also replaces accesses to the first divecomputer in
likely_same_dive to use the maxdepth and meandepth of the dive (those two
slipped through the cracks in the previous commits, it seems).

The existing code only populated the maxtemp based on the samples of a
dive and then in statistics.c checked if there was no such temperature and
replaced it with the water temperature of the first divecomputer.
It makes much more sense to add the water temperature information in every
divecomputer to the min / max calculation during the dive fixup phase.

The fixup_dives() code used to only look at the first divecomputer,
which meant that minimun temperatures etc for the dive would only ever
come from the primary divecomputer.
This splits up the code that walks over the divecomputer into a function
of its own, and iterates over all computers in fixup_dive() calling into
it.

In commit b6c9301e5847 ("Move more dive computer filled data to the
divecomputer structure") we moved the fields that get filled in by the
dive computers to be per-divecomputer data structures.
This patch re-creates some of those fields back in the "struct dive",
but now the fields are initialized to be a reasonable average from the
dive computer data. We already did some of this for the temperature
min/max fields for the statistics, so this just continues that trend.
The goal is to make it easy to look at "dive values" without having to
iterate over dive computers every time you do. Just do it once in
"fixup_dive()" instead.

Instead of maintaining a rolling average and re-calculating it at each
stage, just calculate the surface_pressure average the natural way: as
the sum divided by the number of entries.
This results in a single rounding, rather than doing rounding multiple
times and possibly rounding wrong as a result.
Not that we care all that deeply about the LSB of the mbar value, but
the code is simpler and more obvious this way too.

There are two ways to look at surface pressure. One is to say "what was
the surface pressure during that dive?" - in that case we now return an
average over the pressure reported by the different divecomputers (or the
standard 1013mbar if none reported any).
Or you want to do specific calculations for a specific divecomputer - in
which case we access only the pressure reported by THAT divecomputer, if
present (and fall back to the previous case, otherwise).
We still have lots of places in Subsurface that only act on the first
divecomputer. As a side effect of this change we now make this more
obvious as we in those cases pass a pointer to the first divecomputer
explicitly to the calculations.
Either way, this commit should prevent us from ever mistakenly basing our
calculations on a surface pressure of 0 (which is the initial bug in
deco.c that triggered all this).
Similar changes need to be made for other elements that we currently only
use from the first divecomputer, i.e., salinity.

We had this special logic to not show the end of a dive when a dive
computer shows a series of very shallow samples (basically snorkeling
back to shore after the dive ended). However, that logic ended up being
global per dive, which is very annoying when you have two or more dive
computers, and it decides to cut off the second one because the first
one surfaces.
So get rid of this per-dive state, and just use the plot-info 'maxtime'
field for this (we never used the 'start' case anyway). That way we
will properly cut off boring surface entries only when they are past the
end of the interesting entries of *all* dive computers, and we won't be
cutting things short.

This no longer abuses the dive merging code (which would leave stray
"dives" behind if a gps fix couldn't be merged with any of the dives) and
instead parses the gps fixes into a second table and then walks that table
and tries to find matching dives.
The code tries to be reasonably smart about this. If we have
auto-generated GPS fixes at regular intervals, we look for a fix that is
during a dive (that's likely when the boat where the phone is staying dry
is more or less above the diver having fun). And if we have named entries
(so the user typed in a location name) we try to match them in order to
the dives that happened "that day" (where "that day" is about 6h before
and after the timestamp of the gps fix).
This commit also renames dive_has_location() to dive_has_gps_location() as
the difference between if(!dive->location) and if(dives_has_location) is a
bit too subtle...

This moves the fields 'duration', 'surfacetime', 'maxdepth',
'meandepth', 'airtemp', 'watertemp', 'salinity' and 'surface_pressure'
to the per-divecomputer data structure. They are filled in by the dive
computer, and normally not edited.
NOTE! All actual *use* of this data was then changed from dive->field to
dive->dc.field programmatically with a shell-script and sed, and the
result then edited for details. So while the XML save and restore code
has been updated, all the displaying etc will currently always just show

It used to be that when you checked the "Prefer downloaded" checkmark,
we'd throw away *any* old dive computer data. That was good, because it
allowed us to start from a clean slate when you had some old subsurface
data with questionable dive computer data.
However, it was a bit extreme, and it's really not what you want if you
already have (good) dive computer data from other dive computers.
So this modifies the logic a bit. Instead of throwing away all old dive
computer data, the "Prefer downloaded" checkmark now means:
- the newly downloaded data becomes the "primary" dive computer data
(ie the first in the list)
- if there was old dive computer data that *could* have been from this
new dive computer (ie it didn't have model information, or it had a
matching model but no device ID data), we throw that away
- but any existing dive computer data from other dive computers is left.
This seems to be much closer to what we really would want for a new
"preferred" download.

.. 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 clarifies/changes the meaning of our "cylinderindex" entry in our
samples. It has been rather confused, because different dive computers
have done things differently, and the naming really hasn't helped.
There are two totally different - and independent - cylinder "indexes":
- the pressure sensor index, which indicates which cylinder the sensor
data is from.
- the "active cylinder" index, which indicates which cylinder we actually
breathe from.
These two values really are totally independent, and have nothing
what-so-ever to do with each other. The sensor index may well be fixed:
many dive computers only support a single pressure sensor (whether
wireless or wired), and the sensor index is thus always zero.
Other dive computers may support multiple pressure sensors, and the gas
switch event may - or may not - indicate that the sensor changed too. A
dive computer might give the sensor data for *all* cylinders it can read,
regardless of which one is the one we're actively breathing. In fact, some
dive computers might give sensor data for not just *your* cylinder, but
your buddies.
This patch renames "cylinderindex" in the samples as "sensor", making it
quite clear that it's about which sensor index the pressure data in the
sample is about.
The way we figure out which is the currently active gas is with an
explicit has change event. If a computer (like the Uemis Zurich) joins the
two concepts together, then a sensor change should also create a gas
switch event. This patch also changes the Uemis importer to do that.
Finally, it should be noted that the plot info works totally separately
from the sample data, and is about what we actually *display*, not about
the sample pressures etc. In the plot info, the "cylinderindex" does in
fact mean the currently active cylinder, and while it is initially set to
match the sensor information from the samples, we then walk the gas change
events and fix it up - and if the active cylinder differs from the sensor
cylinder, we clear the sensor data.

I merged things correctly...]

We used to have the rule that a dive trip has to have all dives in it in
sequential order, even though our XML file really is much more flexible,
and allows arbitrary nesting of dives within a dive trip.
Put another way, the old model had fairly inflexible rules:
- the dive array is sorted by time
- a dive trip is always a contiguous slice of this sorted array
which makes perfect sense when you think of the dive and trip list as a
physical activity by one person, but leads to various very subtle issues
in the general case when there are no guarantees that the user then uses
subsurface that way.
In particular, if you load the XML files of two divers that have
overlapping dive trips, the end result is incredibly messy, and does not
conform to the above model at all.
There's two ways to enforce such conformance:
- disallow that kind of behavior entirely.
This is actually hard. Our XML files aren't date-based, they are
based on XML nesting rules, and even a single XML file can have
nesting that violates the date ordering. With multiple XML files,
it's trivial to do in practice, and while we could just fail at
loading, the failure would have to be a hard failure that leaves the
user no way to use the data at all.
- try to "fix it up" by sorting, splitting, and combining dive trips
automatically.
Dirk had a patch to do this, but it really does destroy the actual
dive data: if you load both mine and Dirk's dive trips, you ended up
with a result that followed the above two technical rules, but that
didn't actually make any *sense*.
So this patch doesn't try to enforce the rules, and instead just changes
them to be more generic:
- the dive array is still sorted by dive time
- a dive trip is just an arbitrary collection of dives.
The relaxed rules means that mixing dives and dive trips for two people
is trivial, and we can easily handle any XML file. The dive trip is
defined by the XML nesting level, and is totally independent of any
date-based sorting.
It does require a few things:
- when we save our dive data, we have to do it hierarchically by dive
trip, not just by walking the dive array linearly.
- similarly, when we create the dive tree model, we can't just blindly
walk the array of dives one by one, we have to look up the correct
trip (parent)
- when we try to merge two dives that are adjacent (by date sorting),
we can't do it if they are in different trips.
but apart from that, nothing else really changes.
NOTE! Despite the new relaxed model, creating totally disjoing dive
trips is not all that easy (nor is there any *reason* for it to be
easty). Our GUI interfaces still are "add dive to trip above" etc, and
the automatic adding of dives to dive trips is obviously still based on
date.
So this does not really change the expected normal usage, the relaxed
data structure rules just mean that we don't need to worry about the odd
cases as much, because we can just let them be.

This commit makes deco handling in Subsurface more compatible with the way
libdivecomputer creates the data. Previously we assumed that having a
stopdepth or stoptime and no ndl meant that we were in deco. But
libdivecomputer supports many dive computers that provide the deco state
of the diver but with no information about the next stop or the time
needed there. In order to be able to model this in Subsurface this adds an
in_deco flag to the samples. This is only stored to the XML file when it
changes so it doesn't add much overhead but will allow us to display some
deco information on dive computers like the Atomic Aquatics Cobalt or many
of the Suuntos (among others).
The commit also removes the old event based deco code that was commented
out already. And fixes the code so that the deco / ndl information is
stored for the very last sample as well.

This patch makes a couple of modifications:
1) divelist.c:delete_single_dive() now tries to free all memory associated
with a dive, such as the string values for divemaster, location, notes &
etc.
2) dive.c:merge_text(), now always makes a copy in memory for the returned
string - either combined or one of the two which are passed
to the function.
The reason for the above two changes is that when (say) importing the same
data over and over, technically a merge will occur for the contained dives,
but mapped pointers can go out of scope.
main.c:report_dives() calls try_to_merge() and if succeeds the two dives
that were merged are deleted from the table. when we delete a dive,
we now make sure all string data is cleared with it, but also in the actual merge
itself, which precedes, copies of the merged texts are made (with merge_text()),
so that the new, resulted dive has his own text allocations.

We had logic to remove duplicate dive computer information after merging
dives, but it didn't actually work.
Why? Because we had used the 'res' dive computer pointer to traverse the
list of dive computers, so it no longer actually pointed to the first
dive computer in the result list any more, and so the "remove redundant"
code only removed redundant dive computers from a limited and incomplete
list.

Subject: [PATCH 2/2] Tune the dive joining surface event insert code
So this makes us do surface events only if the samples are more than one
minute apart, and are shallow enough (randomly selected at 5m).
We can add more heuristics. Maybe we should compare the 1-minute sample
time limit of the previous sample to the time to the sample before that:
if some computer (or manually entered dive) has a long time between
*all* samples, we'd make the cut-off time longer.

This tunes the heuristics for when to merge two dives together into a
single dive. We used to just look at the date, and say "if they're
within one minute of each other, try to merge". This looks at the
actual dive data, and tries to see just how much sense it makes to
merge the dive.
It also checks if the dives to be merged use different dive computers,
and if so relaxes the one minute to five, since most people aren't
quite as OCD as I am, and don't tend to set their dive computers quite
that exactly to the same time and date.
I'm sure people can come up with other heuristics, but this should
make that easier too.
NOTE! If you have things like wrong timezones etc, and the
divecomputer dates are thus off by hours rather than by a couple of
minutes, this will still not merge them. For that kind of situation,
we'd need some kind of manual merge option. Note that that is *not*
the same as the current "merge two adjacent dives" together, which
joins two separate dives into one *longer* dive with a surface
interval in between.
That kind of manual merge UI makes sense, but is independent of this
partical change.

Now that we have dive computer device ID fields etc, we can do a much
better job of merging the dive computer data.
The rule is
- if we actually merge two disjoint dives (ie extended surface interval
causing the dive computer to think the dive ended and turning two of
those dives into one), find the *matching* dive computer from the
other dive to combine with.
- if we are merging dives at the same time, discard old-style data with
no dive computer info (ie act like a re-download)
- if we have new-style dive computers with identifiers, take them all.

But we keep the function to find the best offset around, because we may

When we have a preferred dive computer that overrides old information
when merging two dives, we just copy the dive computer data over.
However, we need to clear the source of the dive computer data so that

For now we only have one fixed divecomputer associated with each dive,
so this doesn't really change any current semantics. But it will make
it easier for us to associate a dive with multiple dive computers.

We used to avoid some extra allocations by just allocating the dive
samples as part of the 'struct dive' allocation itself, but that ends up
complicating things, and will make it impossible to have multiple
different sets of samples (for multiple dive computers).
So stop doing it. Just allocate the dive samples array separately.

When this was first implemented the assumption was that a downloaded dive
that is to be merged with an existing dive would have the same time stamp.
But as Linus pointed out even back then, this does fail if a dive has been
merged with a download from a different dive computer before (think:
download from computer a, then download same dive from b, then improve
something in the parsing from computer a and try to redownload; the time
stamp could have changed).
This commit also fixes a silly omission in the merge_dives() function
(which ended up ALWAYS prefering the downloaded dive) and finally
implements the necessary changes to mark dives downloaded from a Uemis SDA
as well.
