cd5e17cf79 Cleanup: Unify qthelper.h and qthelperfromc.h
Since all qt-helpers are defined in qthelper.cpp, there seems to be
no reason to have two include files. By unifying the two files,
duplication and inconsistencies are removed. The C++-only part is
simply compiled away with #ifdefs.

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.

Improvement of dive planner profile display:

Do some simplification of my alterations to diveplannermodel.cpp

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.

8e21a65653 Localize global planner state
For UI responsiveness, we need to be able to run the planner in the background. This needs the
planner state to be localized (and we need to pass a pointer around).

In order to not let too many lines overrun (and to save typing in the future)
I have renamed instances of struct deco_state to ds. Yes this should have gone
to a separate commit but I accidentally commit --amend'ed it.

Computing of planner variations is temporarily disabled.

Unlock the planner when returning early

So we don't deadlock in add dive and recreational mode (which
use the planner without actually planning).

4a727c64d9 VPMB: calculate deco_time assuming final ascent always takes the same time
If we consider the actual time to ascend from the final stop when calculating
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.

This corrects the issue where the displayed ceiling in the profile was
"broken" by the planner, especially for shorter and shallower dives.

Also fixes issue outside of planner where the deepest VPM-B ceiling was shown
too early, messing up the deco_time calculation.

4158a4c7de init_deco correctly identify previous dives and report overlapping dives
When changing the date/time of a dive in the planner the dive may end
up in a totaly new position in respect to date/time of other dives in
dive list table. It can be moved to the past or the future before or after
other existing dives. It also could overlap with an existing dive.

This change enables identification of a new "virtual" dive list position
and based on this starts looking for previous dives.
Then it (as before the change) does init the deco calculation with any
applicable previous dive and surface interval.
If some of these applicable dives overlap it returns a neg. surface time
which is then used in the planner notes to prohibit display of results.

When calculating the dive plan in the planner don't accidently use
another gas with same gasmix instead of the gas stored as
"best_first_ascend_gas".
This is important if you have e.g. a bottom stage and back gas with
same gas mix because then you always want to start your ascent with
the gas you used in last entered dive planner point.

11a0c0cc70 Unify sample pressure and o2pressure as pressure[2] array
We currently carry two pressures around for all the samples and plot
info, but the second pressure is reserved for CCR dives as the O2
cylinder pressure.

That's kind of annoying when we *could* use it for regular sidemount
dives as the secondary pressure.

So start prepping for that instead: don't make it "pressure" and
"o2pressure", make it just be an array of two pressure values.

NOTE! This is purely mindless prepwork.  It literally just does a
search-and-replace, keeping the exact same semantics, so "pressure[1]"
is still just O2 pressure.

But at some future date, we can now start using it for a second sensor
value for sidemount instead.

dfe5092222 Identify user provided notes in plain text in replan
This is another attept at the problem if identifying a potentially
user supplied text in the dive notes upon replannig a dive.

It gets rid of the user visable position markers (*!* and ***) and
cirumvents problems with mark-up by first converting the old notes
to plan text (assuming that user only enters plain text in the notes
field as we do in other places as well). Then the automatically added
part is identified by locating the disclaimer in the text (if the user
edited/delted the disclaimer or changed langue in between it is her
problem to manually delete the old plan).

Everything from the disclaimer on is deleted and replaced by the new plan.

If the disclaimer is not found, the new plan is appended to the old notes.
This way we make sure no information gets automatically deleted.
