2c794348c1 Planner: Add checkbox to force OC bailout
This adds a checkbox for rebreather modes of the planner

this is not practical when manually searching for the

605e1e19ed Cleanup: const-ify functions taking pointers to events
This is another entry in the series to make more things
"const-clean" with the ultimate goal of merge_dive() take
const pointers.

This concerns functions taking pointers to events and
the fallout from making these const.

The somewhat debatable part of this commit might be
that get_next_event() is split in a two distinct
(const and non-const) versions with different names,
since C doesn't allow overloading. The linker should
recognize that these functions are identical and remove
one of them.

360f07e453 Cleanup: pass gasmix by value
In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.

Note that on common 64-bit platforms struct gasmix is the size
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.

Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
invasive change that going back to pointers is probably the
least of our worries.

This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter
will not be changed [unless there are references to said parameter]).

5c4569247a Cleanup: unify get_gas_at_time() and get_gasmix()
There were two functions for getting gas-mixes at a certain timestamp:
- get_gasmix() for repeated queries.
- get_gas_at_time() for a single query.
Since the latter is a special case of the former, simply call
the former in the latter. Moreover, rename to get_gasmix_at_time()
for consistency.

Replace on get_gasmix() call, which was outside of a loop by the
corresponding get_gasmix_at_time() call.

769aca9e95 equipment: sanitize 'tank_info' loop limits
In a number of places the global 'tank_info' array
is being iterated based on a 'tank_info[idx].name != NULL'
condition.

This is dangerous because if the user has added a lot of tanks,
such loops can reach 'tank_info[MAX_TANK_INFO]'. This is an
out of bounds read and if the 'name' pointer there happens to be
non-NULL, passing that address to a peace of code that tries
to read it (like strlen()) would either SIGSEGV or have undefined
behavior.

Clamp all loops that iterate 'tank_info' to MAX_TANK_INFO.

4c73ada121 Adapt the dive planner to do bailout
Ensure that calls to add_segment() all have a appropriate divemode
for that part of the dive plan. In the case of plan(), the existing
variable 'divemode' was directly passed to add_segment. For the
functions interpolate_transition() and trial_ascent(), the divemode
was obtained by including it in the parameter list of the function
and divemode supplied by the calling function.

27a0542220 Implement bailout outside of the dive planner
This is the second step for implementing bailout. The indirect
calls to fill_pressures through add_segment() (in deco.c) are
addressed. Bailout is now fully implemented in the dive log but
not in the dive planner.
1) The parameters to add_segment() are changed to take a
   divemode as the second last parameter, and not a *dive.
2) Call to add_segment() in profile.c and in divelist.c are
   adapted. In divelist.c some calls to add_segment were left
   using dc-> divemode instead of possible bailout. This appears
   tp be the most appropriate route.
3) The functions get_divemode_from_time() and get_next_divemodechange()
   in dive.c have had some small changes.
4) The calls to get_segment(0 in planner.c were changed to reflect
   the new parameter list, but not updated to reflect bailout. This
   is the next step.

ac1ec486ae Planner: Unify final ascent rates in plan() and fake_dc()
When generating fake profiles for manually entered dives, fake_dc() and
plan() used different final ascent rates of 5 m/min and 4.5 m/min,
respectively. This led to dives that were 6 seconds longer than entered
by the user and to confusion. See #554.

Therefore, use the same ascent rate taken from the preferences field
flag.ascratelast6m in both cases.

9a8bab21c9 Improve profile display in planner
This patch allows the planner to save the last manually-entered
dive planner point of a dive plan. When the plan has been saved
and re-opened for edit, the time of the last-entered dive planner
point is used to ensure that dive planning continues from the same
point in the profile as was when the original dive plan was saved.
Mechanism:

1) In dive.h, create a new dc attribute dc->last_manual_time
   with data type of duration_t.
2) In diveplanner.c, ensure that the last manually-entered
   dive planner point is saved in dc->last_manual_time.
3) In save-xml.c, create a new XML attribute for the <divecomputer>
   element, named last-manual-time. For dive plans, the element would
   now look like:
   <divecomputer model='planned dive' last-manual-time='31:17 min'>
4) In parse-xml.c, insert code that recognises the last-manual-time
   XML attribute, reads the time value and assigns this time to
   dc->last_manual_time.
5) In diveplannermodel.cpp, method DiveplannerPointModel::loadfromdive,
   insert code that sets the appropriate boolean value to dp->entered
   by comparing newtime (i.e. time of dp) with dc->last_manual_time.
6) Diveplannermodel.cpp also accepts profile data from normal dives in
   the dive log, whether hand-entered or loaded from dive computer. It
   looks like the reduction of dive points for dives with >100 points
   continues to work ok.
The result is that when a dive plan is saved with manually entered
points up to e.g. 10 minutes into the dive, it can be re-opened for edit
in the dive planner and the planner re-creates the plan with manually
entered points up to 10 minutes. The rest of the points are "soft"
points, shaped by the deco calculations of the planner.

Improvements: Improve code for profile display in dive planner

This responds to #1052.
Change load-git.c and save-git.c so that the last-manual-time is
also saved in the git-format dive log.

Several stylistic changes in text for consistent C source code.

a748e7f239 Unify float calulations: use double
Internal floating point (FP) calculations should be performed using double
unless there is a very good reason. This avoids headaches with conversions.
Indeed, the vast majority of FP calculations were already done using double.
This patch adapts most remaining calculations. Not converted where things
that were based on binary representations and variables which weren't used
anyway.

An analysis of all instances follows:

core/plannernotes.c, l.404:

This was a comparison between two floats. On the left side, first an integer
was cast to float then multiplied with and integer and divided by a constant
double. The right hand side was an integer cast to a float. Simply divide by
1000.0 first to convert to double and continue with calculations. On the right
hand side, remove the cast, because the integer will be implicitely cast to
double for comparison. This conversion actually emits less instructions,
because no conversion to double and back is performed.

core/planner.c, l.613:

Same analysis as previous case.

subsurface-desktop-main.cpp, l.155:

A local variable representing the version OpenGL version. Turn this into
integer logic. Not only does this avoid dreaded FP rounding issues, it also
works correctly for minor version > 10 (not that such a thing is to be
expected anytime soon).

abstractpreferenceswidget.[h/cpp]:

A widget where the position is described as a float. Turn into double.

desktop-widgets/divelogexportdialog.cpp, l.313:

total_weight is described as float. Use double arithmetics instead. This
instance fixes a truncation warning emitted by gcc.

deco_time, then slowing the final ascent can lead to the final stop being
extended, which is completely nonsensical.  For consistency with the original
VPMB implementation, we can't ignore the final ascent time completely, but if
we assume it is always the same (take default ascent rate of 9m/min) then
slower the final ascent won't lead to a longer final stop.
