We only store the model/deviceid/nickname for those dive computers that
are mentioned in the XML file. This should make the XML files nicely
selfcontained.
This also changes the code to consistently use model & deviceid to
identify a dive computer. The deviceid is NOT guaranteed to be collision
free between different libdivecomputer backends...

Having it there with the model information seemed to make sense but on
second thought it's the wrong spot to keep that information, especially
since we were storing it in the XML file in every single dive.
This change removes the nickname member from the divecomputer and makes
the rest of the code reasonably self consistent. It does not add much of
the new code for the new design to handle nicknames.

This adds the capability to actually view all your dive computers, by
adding a menu item under "Log"->"View"->"Next DC" to show the next dive
computer.
Realistically, if you actually commonly use this, you'd use the
accelerator shortcut. Which right now is Ctrl-C ("C for Computer"),
which is probably a horrible choice.
I really would want to have nice "next/prev dive" accelerators too,
because the cursor keys don't work very well with the gtk focus issues.
Being able to switch between dives would also make the "just the dive
profile, maam" view (ctrl-2) much more useful.
The prev/next dive in the profile view should probably be done with a
keyboard action callback, which also avoids some of the limitations of
accelerators (ie you can make any key do the action). Some gtk person,
please?
Anyway, this commit only does the dive computer choice thing, and only
using the accelerators.

This changes two things to improve the appearance of the profile:
- the partial pressure scale is now in 0.5 increments if the total is <= 4
and in 1.0 increments if it is > 4.
- the depth marker lines end slightly below the depth chart so that we no
longer have overlap between the depth scale and the partial pressure
scale.

In profile.c:create_plot_info(), store the last address in which
memory was allocated for the plot data entries in the static
variable "last_pi_entry". If "last_pi_entry" isn't a NULL
pointer in each call to create_plot_info(), free memory at that
address.

We maintain a list of dive computers that we know about (by deviceid) and
their nicknames in our config. If the user downloads dive from a dive
computer that we haven't seen before, we give them the option to set a
nickname for that dive computer. That nickname is displayed in the profile
(and stored in the XML file, assuming it is not the same as the model).
This implementation attempts to make sure that it correctly deals with
utf8 nicknames.

Showing the depth scale all the way to the bottom of the profile plot
looks strange when there are partial pressure graphs down there. So
instead we only plot down to the next marker below the maximum depth of
the actual dive.

This splits the dive time, depth, pressure and temperature maxima and
minima setup from the per-dive-computer "create_plot_info()" function
into one setup function that walks _all_ the dive computers, so that we
have a global maxima and minima.
That way the graph scaling we set up will now fit the data from all dive
computers rather than just the particular one we are plotting. So if
you switch back-and-forth between computers, the scale (which is defined
by the extremes) remains the same.

This now takes the He percentage into account when matching tanks. Given

This commit changes the code that was recently introduced to deal with
deco ceilings. Instead of handling these through events we now store the
ceiling (which in reality is the deepest deco stop with all known dive
computers) and the stop time at that ceiling in the samples.
This also adds support for NDL (non stop dive limit) which both dive
computers that appear to give us ceiling / deco information appear to
give us as well (when the diver isn't in deco).
If the mouse hovers over the profile we now add support for displaying the
NDL, the current deco obligation and (if we are able to tell from the
data) whether we are at a safety stop.

I was a little too eager to add the deco feature to Subsurface. Jef and I
went back and forth a few more times and the definition of those events
changed. I guess I shouldn't have commited that code until the
corresponding libdivecomputer code had been pushed.
This commit now brings us in sync with the current master of
libdivecomputer (but should compile with 0.2 as well - only deco events
won't work then).
One issue that I see is that deco / ndl aren't really a good fit for the
event model. I actually disabled the drawing of the little yellow
triangles for ndl events as for example on the Uemis those events are
created whenever the remaining non stop time changes - and that can be
every few seconds.
The correct solution may be to treat this as a function of the samples,
but for now this works and is tested with both OSTC and Uemis SDA.

This actually triggers for one of our insane test dives (test15): it has
no samples, so we created a fake dive computer entry with the a fake
profile in it, but we didn't copy the events over.
Having a dive with no samples, yet having events from the dive computer,
sounds pretty bogus. But that test-case did show that when that bogus
situation happens, we had two independent buglets: (a) we didn't insert
the entries in the fake dive computer entry we used and (b) we would
then mix up the events of the fake dive computer entry with the first
dive computer of a dive.
Fix this, just to make test15 happy again. And eventually, when we
actually plot the information for multiple dive computers, fixing case
(b) would become necessary even for real dives.

The code in commit f99e1b476b18 "Trim the dive to exclude surface time at
beginning and end" failed rather badly if a dive has no samples at all -
which is true for many of our test dives.

and end times.

Commit 6c52e8a2e516 ("Add plotting of the deco ceiling") for some
totally unexplained reason deleted one "else" statement, resulting in
some plot events not having a time at all. Which causes various really
odd issues if you hit that situation, including divide-by-zero etc due
to the difference in times between events being nonsensical.
It's just some odd mistake that was entirely unrelated to the other
changes in that commit.

This shows the values for all the graphs that are shown (depth,

When we calculate the interval for the tick-marks for the dive, we need
to limit 'i' to be within the size of the array. The code does that
with a "i < 8" check, but the fact is, we must never increment past the
last entry, which is 7 (the size of the array is 8, but the last valid
index is 7).
This only happens for unrealistically long dives. Which you can trigger
either by inputting insane values for a manually created dive, or by
merging two dives that are consecutive, but not close to each other
time-wise (eg on different days ;)

This extends on our current tooltip logic (which shows events when you
mouse over them) to show tooltips for the whole profile area.
If you mouse over an event, that is still shown in the tooltip, but
even in the absense of events, the tooltip will be active, and mousing
over the profile area will show the time, depth and pressure.
This can certainly be improved upon further, but even in this form it is
useful.

We don't change any of the samples, we just don't plot (or consider for
dive time / mean calculations) the samples at the beginning or end of the
dive that are less than a certain threshold under water. Right now that's
an arbitrary 75cm which seems to Do The Right Thing(tm) for the dives I
tried this with - but I'm happy to look at other values if this causes
problems for people with dive computers I do not have access to.

We now throw away redundant events, just as we throw away other redundant
data coming from the dive computer. Events are considered redundant if
they are less than 61 seconds apart and identical.
This also improves the display of the remaining events in the profile as
we now show the value of the event, if it is present (for example for a
deco event we show the duration of the deepest stop).
Finally, for events that define a range (so they set the beginning flag
and assume and end flag some time later) we no loger show the triangle but
assume that some other code handles visualizing them (as happens for the
ceiling events).

Based on suggestions from Linus (and a few iterations) we now simply have

Plot a red-shaded area on top of the depth profile to indicate the deco
ceiling (i.e., the area into which it isn't save to ascend at this point

So far this is of very limited use as libdivecomputer doesn't give us the
necessary information to plot this. I have sent patches for the OSTC to
Jef, hoping that he will include them in an update. I don't know how many
other dive computers will make this data available - I still need to add
this to our native Uemis support.

This commit moves the calculations slightly later in create_plot_info()

We always want to print absolute maxima and minima - but not when multiple
