bdedf46e4c Get rid of compiler warning on format strings
This gets rid of compiler warnings "format not a string literal and no
format arguments [-Wformat-security]". E.g. when building distribution
packages these warnings are often treated as errors preventing the
build (with good reason).

193d20c479 Next step towards working translations
This may seem like a really odd change - but with this change the Qt tools
can correctly parse the C files (and qt-gui.cpp) and get the context for
the translatable strings right.

It's not super-pretty (I'll admit that _("string literal") is much easier
on the eye than translate("gettextFromC", "string literal") ) but I think
this will be the price of success.

4b12f28ca4 First steps towards removing glib dependencies
- remove the build flags and libraries from the Makefile / Configure.mk
- remove the glib types (gboolean, gchar, gint64, gint)
- comment out / hack around gettext
- replace the glib file helper functions
- replace g_ascii_strtod
- replace g_build_filename
- use environment variables instead of g_get_home_dir() & g_get_user_name()
- comment out GPS string parsing (uses glib utf8 macros)

This needs massive cleanup, but it's a snapshot of what I have right now, in
case people want to look at it.

23ce6b8bec When adding a dive, make the final ascent slower
Simply trying to role-model safe behavior I guess. Fundamentally all this
should be configurable (so I added comments about that on the planner side
as well).

One of the interseting side effects of this implementation is that if the
user removes the safety stop and comes up directly from a deeper depth,
the slope of the ascent will change at 5m :-)

56535e4b3b Only calculate deco stops in planner mode
In add dive mode simply bring the diver safely back to the surface
(currently with a fixed ascent rate of 30ft/min (or 9m/min)).

We should make that rate configurable (for the planner as well as the dive
add function). Also, the dive add function should offer to automatically
include a safety stop.

ef0272f5ef Perform deco calculation for plan
This uses a bunch of default values that we eventually need to get from
the UI, but it's a first step towards a working dive planner.

This exhibits some graphical artifacts when running, but other than that
appears to be mostly correct.

Things go far worse if I enable the changing of the scale once the deco
makes the dive longer than the displayed time window. Things quickly
spiral out of control.

596095389b Start hooking in the deco calculations
I expanded the DiveHandler to include the actual time / depth of each
node on the graph - this way things will stay consistent if we need to
rescale the graph.

One thing that this makes obvious is that the whole design for the
planner so far assumes metric data. We need to make sure this works well
with feet instead of meters as well (and that it uses the information in
the units settings).

With this change we actually create a dive based on the plan input and
add the deco stops (if needed) to it - but we don't do anything with the
results of those calculations, yet.

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.

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...

4401132836 Fix potentially broken white space truncation on certain Windows versions
Testing the Planner in Subsurface on a Windows XP SP3 installation,
shows corrupted UTF-8 strings in the case of Cyrillic locales, but
possibly others as well. Instead limited to the Planner, this affects
the entire application.

After some examination it appears that <ctype>'s isspace() in MSVC
on the tested version of Windows is broken for some UTF-8 characters,
after enabling the user locale using: setlocale(LC_ALL, "");

For example, characters such as the Cyrillic capital "BE" are defined as:
0xD091, where isspace() for the first byte returns 0x08, which is the
bytemask for C1_SPACE and the character is treated as space.
After a byte is treated as space, it is usually discarded from a UTF-8
character/string, where if only one byte left, corrupting the entire
string.

In Subsurface, usages of string trimming are present in multiple
locations, so to make this work try to use GLib's g_ascii_isspace(),
which is a locale agnostic version of isspace().

Affected versions of Windows could be everything up to XP SP3,
but not apparently Vista.

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.

6b458ad7fa Ensure that planner warnings get shown before calculations are run
Linus pointed out that the warning wasn't shown until the main loop got
control back, so even a gtk_widget_show_all() doesn't really help to make
sure that things are shown right then.

This commit adds a little loop to handle all pending gtk_events before
exiting the show_error() function. Now the warning should be shown BEFORE
a potentially slow calculation gets started.

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).

5a540fb9d1 Remove rounded O2 in air
To quote Linus, gentle as always:

 Stuff like this is just BS.

 Don't do it. You already fixed the bug with matching gas change events,
 so adding this idiotic workaround no longer fixes anything, and its
 confusing and actively misleading.

 It's not even percent. It's still permille, just rounded. So it's a
 nonsensical number and a misleading name. Just delete it as the abortion
 it is. It is only going to cause more problems later.

 Just use the correct value.

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.

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.

aa55bda944 Don't allow to plan dives out of order
The planned dive always has to be the last dive in the dive list. To make
sure of that we interpret the relative start time to be relative to either
the current time or the end of the last dive, whichever is later.

This fixes a bug where we would delete the wrong dive and get our data
structures confused by planning multiple dives out of order.

e3a8ed5183 Massive cleanup
Mostly coding style and whitespace changes plus making lots of functions
static that have no need to be extern. This also helped find a bit of code
that is actually no longer used.

This should have absolutely no functional impact - all changes should be
purely cosmetic. But it removes a bunch of lines of code and makes the
rest easier to read.

a61877d1d4 Add missing strings for translations
Mostly in new code, but some of them are strings in older code that have
been missed in the past.

55b3fd12a8 Make dive planner more useful for closed circuit diving
Add a sample at time 0 to allow for a pO2 from the start of the dive.
Remember the last pO2 so it doesn't have to be repeated (and the right
thing happens for the planned part of the dive).

This still doesn't allow us to change the setpoint at a certain depth
(which would be analogous to being able to switch to a certain gas at a
certain depth in OC plans), but with this commit it's already usable.

This commit also fixes a couple of small bugs in commit b8ee3de870fa
("Dive planning for closed circuit rebreather") where a pO2 of 1.1 was
hardcoded in one place, throwing off all plan calculations and integer
math was used to calculate a floating point value (leading to most pO2
values actually used being 1.0).

9df9fc088d Dive planning for closed circuit rebreather
This misses a single issue to be used as a base for further discussion:
The CC setpoint is used for the next segment, not the one specified for. I
also have in mind to modify the existing code to use setpoints specified
in mbar and plain integer instead of float values.
