478baf1076 Replace GError handling with a kMessageWidget based approach
Instead of passing pointers to GError around we pass just pointers to
error message texts around and use kMessageWidget to show those. Problem
is that right now the close button on that doesn't do a thing - so the
error stays around indefinitely. Oops.

f3f7bf51fa Merge branch 'Qt'
After the 3.1 release it is time to shift the focus on the Qt effort - and
the best way to do this is to merge the changes in the Qt branch into
master.

Linus was extremely nice and did a merge for me. I decided to do my own
merge instead (which by accident actually based on a different version of
the Qt branch) and then used his merge to double check what I was doing.

I resolved a few things differently but overall what we did was very much
the same (and I say this with pride since Linus is a professional git
merger)

Here's his merge commit message:

    This is a rough and tumble merge of the Qt branch into 'master',
    trying to sort out the conflicts as best as I could.

    There were two major kinds of conflicts:

     - the Makefile changes, in particular the split of the single
       Makefile into Rules.mk and Configure.mk, along with the obvious Qt
       build changes themselves.

       Those changes conflicted with some of the updates done in mainline
       wrt "release" targets and some helper macros ($(NAME) etc).

       Resolved by largely taking the Qt branch versions, and then editing
       in the most obvious parts of the Makefile updates from mainline.

       NOTE! The script/get_version shell script was made to just fail
       silently on not finding a git repository, which avoided having to
       take some particularly ugly Makefile changes.

     - Various random updates in mainline to support things like dive tags.

       The conflicts were mainly to the gtk GUI parts, which obviously
       looked different afterwards.  I fixed things up to look like the
       newer code, but since the gtk files themselves are actually dead in
       the Qt branch, this is largely irrelevant.

       NOTE! This does *NOT* introduce the equivalent Qt functionality.
       The fields are there in the code now, but there's no Qt UI for the
       whole dive tag stuff etc.

    This seems to compile for me (although I have to force
    "QMAKE=qmake-qt4" on f19), and results in a Linux binary that seems to
    work, but it is otherwise largely untested.

Now it supports an (at this point, fixed) set of tags that can be assigned

as it gets some additional support for hiding such dive and marking dives
as (in)valid from the divelist).

99070c49e2 Fix get_cylinder_index() gasmix comparisons
get_cylinder_index() looks up which cylinder to use based on the
gaschange event that describes the mix.  However, it was both buggy and
not very good.

It was buggy because it didn't understand about our air rules, and it
was not very good because it required an exact match (after rounding our
permille-based numbers to percent).

So fix it to use the right permille values, and look for a closest match
(using the normal sum-of-squares distance function - although I wonder
if we should consider helium percentages to be "more important" and give
them a stronger weight).

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...

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.

It very much is an approximation, but it's closer to reality than

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.

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

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).

Populate during dive fixup as the maximum depth shown by all the
divecomputers. Use this value (instead of the one in the first
divecomputer) in printing, statistics, etc.

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.

9750b0ce06 The 'gasmix' argument to add_segment() is read-only
We'll want to use a 'static const' gasmix for the upcoming no-fly-time
code, so prepare for it by just marking the read-only gasmix argument as
'const'.
