8a5792d473 Manually add gas changes to a dive
Create a little widget that lists all the gases / tanks we know about and
allow the user to pick one of them.

Turns out that add_event only added events at the end of the list - but we
treat that list as chronologically sorted. So I fixed that little
mis-feature as well.

This does raise the question whether we need the inverse operation
(removing a gas change). And if there are other things that we should be
able to manually edit, now that we have the infrastructure for this neat
little context menu...

See #60 -- this doesn't address all of the issues mentioned there, but at
least deals with the 'headline' of the feature request...

d2f9ee8d45 Planner: don't use the planned dive for relative start time
The existing code has an embarrassing error in its logic. It picked the
last dive in the table and made sure that the relative start time was
either N minutes after 'now' or N minutes after the last dive ends,
whichever is later.

But once the planned dive has been added to the dive list (so once we have
a first depth and time entry, that last dive now is the planned dive. And
every time focus left the start time field the start time would be
recalculated relative to the end of the dive we are currently planning.

With this patch we instead simply remember the number of the last dive
just as we create the dive plan and use that to look up the end time of
previous dive. I could have just stored that end time but I figured maybe
there could be other reasons to go back to the last dive before the
planned dive, so this seemed cleaner.

308d71ec39 Take incompressibility of gas into account at higher pressures
This creates a helper function called "gas_volume()" that takes the
cylinder and a particular pressure, and returns the estimated volume of
the gas at surface pressure, including proper approximation of the
incompressibility of gas.

It very much is an approximation, but it's closer to reality than
assuming a pure ideal gas.  See for example compressibility at

d753805542 Fix cylinder air size calculations
Commit 90d3c5614a ("Centralising and redefining values as integers")
broke SAC-rate calculations. In particular, it changed "to_ATM()": to
use the centralized SURFACE_PRESSURE helper define, but in the process
it changed a floating point calculation to an integer calculation, and
it threw away all the fractional details. Any user of "to_ATM()"
basically dropped to an accuracy of a single atmosphere.

The good news is that we didn't use to_ATM() for things like depth
calculations, but only for cylinder pressures. As a result, the error
ends up being relatively small, since the pressures involved are big,
and thus the error of rounding to whole atmospheres is usually in the
1% range. The cylinder sizing tends to be off by more than that
anyway. But it was wrong, and not intentional.

1e04e08064 When only a dive trip is selected, select all the dives in the trip
This does a final pass after all the selection logic, and notices if we
have dive trips that are selected, but that have no dives in them
selected.  In that case, we assume that the user wanted to select all
dives in that trip.

NOTE! This still allows a range selection that selects the dive trip
entry and a few dives under the trip.  If a trip has any dives selected
in it, we leave that manual selection alone.  So this new logic really
only triggers on the case where somebody selected *just* the trip.

Note: unselecting the trip still leaves the dives under it selected,
because having a dive trip that isn't selected have all the dives under
it be selected is normal, and we can't recognize that as some kind of
special event.

0cde0eff10 Rewriting the error handling in planner.c
Printf is not a way to issue warnings and errors. This is a very late
addition but seems necessary for a viable release of the planner.

This also adds one artificial limit and two warnings:

a) no dives deeper than 400m
b) warning of potentially very long calculation times for dives longer
   than 3h (180min) before the ascent and dives deeper than 150m

It also creates quite a number of new strings that need to be translated
(and marks a few existing ones for translation as well).

5e93469f35 Fix gas handling in planner
Two separate bugs.

a) Air cylinders were created with o2=209 and no other value set.
sanitize_gasmix() turned that into o2=0 which meant that this cylinder was
now identified as "nodata", i.e., unset.
We now set a fake cylinder name to deal with that issue.

b) the gaschange event is inherited from libdivecomputer and therefore
only supports 1 percent granularity for o2 and h2. Since we didn't round
when assigning the value we ended up with air being stored as o2=20 he=0
which of course then didn't match air anymore (which we have defined as
208 <= o2 <= 210).
We now use o2=210 for air in the planner and carefully round the permille
values whenever we convert into percent - and compare gases with percent
granularity as well.

A better fix for b) would be to change the Subsurface event to not simply
copy the libdivecomputer behavior and use percent granularity but support
permille instead. But this closely before the 3.0 release that seemed like
a far too invasive change to make - the changes to the planner should have
no impact outside the planner module.

ebcbe5aedd Finish removing accesses to first divecomputer instead of dive
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.

b9865d6bbc Move duration to dive structure and replace accessor function
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).

926fcef2a1 Do more dive fixup for each dive computer
In commit b6c9301e58 ("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.

61861d2611 Clean up the handling of surface pressure
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.

f507b05927 Get rid of dive->{start,end}
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.

635c28923d Better algorithm to merge gps locations & locations names from webservice
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...

Side note: just comparing deviceid is not correct.  We should pass in
the device model too.  But again, that will realistically never really
matter, since non-Uemis importers will generate complex SHA1 hashes of
the dive data for the dive ID, so a collision with the Uemis numbers is

peoples computers that you may not actively use, but you want to see if
you end up loading multiple XML files in one go.

So there's just no compelling reason to not just save all the info we
have.  And this will make it less painful to remove the "use system
config for dive computer nicknames", because you can also use this to
continue to gather dive computer info in a separate XML file if you want

413b9026dd Fix temperature rounding issues
Temperatures can actually be negative, which means that rounding by
adding 0.5 and casting to 'int' is not correct.

We could use '(int)(rint(val))' instead, but the only place we care
about might as well just print out the floating point representation
with a precision of two digits instead.  So if you have a dive computer
that gives you the precision, you might see '3.5˚C' as the temperature.

Remove the helper functions that nobody uses and that get the rounding
wrong anyway.

displayed.

I've also switched map tiles from OpenStreetMap to Google Maps just to
show off that we can.

c3a08ff056 Add diveplan to the dive notes
This makes it easy to print out a dive plan - it's simply stored in the
notes of the simulated dive we create.

189cba7fd2 Add code to enter SAC rates for dive planning
This just provides the infrastructure to enter the data, nothing is
calculated, yet.

This adds a new get_thousandths() helper function so we can enter
information of the 'mili-' type as decimal values. So things like
"14.5 l/min" or "0.75 cuft/min" are parsed correctly and converted
into a ml value.

In the process of implementing that I also fixed a bug introduced in
commit ab7aecf16e ("Simplify dive planning code") which broke the
get_tenth() function.

678fffdcf4 Added the OS dependent function subsurface_launch_for_uri()
Opening URI addresses from Subsurface does not work on Windows using
the latest GTK bundle from the Gnome website. The reason lies in GIO
and GLib and how it obtains assigned applications for protocols and MIME
types.

While gtk_show_uri() should be viable for both linux.c and macos.c,
in windows.c ShellExecute() is used, which provides proper support
for the URI calls.

subsurface_launch_for_uri() returns TRUE on success.

90d3c5614a Centralising and redefining values as integers
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.

23ce727e62 Add support for MOD, EAD, AND and EADD in the mouse over display
- 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.

8ff350387d Work on a dive localisation tool using GPS coordinates
For each dive recorded, place their GPS coordinates onto a map using the
OSM-GPS-MAP library.

This map is accessible via the "log" menu or the shortcut ctrl+M (M as map).

We check for the GPS coordinates "0, 0" which are the default when we do not
have real GPS coordinates set.

[Dirk Hohndel: fixed int/float math confusion, fixed some whitespace and
               coding style issues, cleaned up some comments, added a
	       missing cast to prevent a compiler warning]

6a10700ca5 Add default filename and divelist font to prefs structure
.. and add the usual logic to not save the default values.

This also simplifies the initial system-specific setup of both of these:
since we have defaults for all the preferences that get set up at
startup, we can just initialize those defaults to the system-specific
fonts then and there.

868a2cc090 Split up preference data structure definition into 'pref.h'
.. 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.

ec38d3708d Move device_info handling into a new 'device.c' file
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.
