e362afe43c Cleanup: remove UTF8 macros
At some places we use UTF8 string literals. Therefore, we effectively
only support UTF8 build systems. We might just as well remove all
the other UTF_* macros and use direct string literals.

7067e33596 Undo: select dives after add, remove, merge, split dive commands
Select the proper dives after the add, remove, split and merge
dives commands on undo *and* redo. Generally, select the added
dives. For undo of add, remember the pre-addition selection.
For redo of remove, select the closest dive to the first removed
dive.

The biggest part of the commit is the signal-interface between
the dive commands and the dive-list model and dive-list view.
This is done in two steps:
1) To the DiveTripModel in batches of trips. The dive trip model
   transforms the dives into indices.
2) To the DiveListView. The DiveListView has to translate the
   DiveTripModel indexes to actual indexes via its QSortFilterProxy-
   model.

For code-reuse, derive all divelist-changing commands from a new base-class,
which has a flag that describes whether the divelist changed. The helper
functions which add and remove dives are made members of the base class and
set the flag is a selected dive is added or removed.

To properly detect when the current dive was deleted it
became necessary to turn the current dive from an index
to a pointer, because indices are not stable.

Unfortunately, in some cases an index was expected and these
places now have to transform the dive into an index. These
should be converted in due course.

6e4a253896 Profile: fix SAC calculation for air dives
Commit f5b11daffd changed gasmix
arguments and return values to be passed by value instead of
using pointers.

Notably, get_gasmix() is fed a default-value and returns a
new value. In the old code, NULL was passed in in a first
loop iteration and non-NULL was always returned in the first
iteration. Thus, an equality comparison of passed-in an
returned gasmix would always fail in the first loop iteration.

The new code passed in air as default. Now if air was also
returned, then the matching gases were not calculated in
calculate_sac(). To revert to the old behavior, pass in
an invalid gasmix.

Moreover, give names to the invalid and air gasmixes.

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]).

f5b11daffd Cleanup: return gasmix by value
Currently, get_gasmix_from_event() and get_gasmix() return pointers
to either static or to (possibly changing) dive data. This seems like
a dangerous practice and the returned data should be used immediately.

Instead, return the gasmix by value. This is in preparation of
const-ifying input parameters of a number of core functions, which
will ultimately let the merge() function take const-arguments in
preparation of undo of dive-merging.

On common 64-bit systems gasmix (two "int"s) is the size of a pointer
and can be returned in a register.

On 32-bit systems a pointer to the struct to be filled out will be
passed.

Since get_gasmix() now returns a value, the first invocation is
tested by a NULL-initialized "struct event *". Document this in
a comment.

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.

cf377beb2e Incorporate bailout events in CCR & PSCR gas calculations.
This is a first step to interpret bailout events.
1) The event structures have a new attribute: divemode.
   Currently interpreted dive modes are OC, CCR, PSCR.
2) When doing fill_pressures(), the calculation is aware
   of divemode. When divemode is OC (==bailout), then
   the appropriate calculations of gas pressures are done.
3) Two new functions get_next_divemodechange() and
   get_divemode_at_time() are created to find divemode
   changes in the events linked list and to determine
   the dive mode at any point during the dive.
4) fill_pressures gets a small amendment to facilitate
   the correct calculations, depending on divemode.
The cases where fill_pressures() is used *outside the planner*
are changed. The result is that, for dives with bailout, the
correct gas pressures are shown on the dive profile. The
deco for bailout dives is not yet correct. This is the
next step.

81a812539c Plot OC-pO2 graph for SCR dives
This commit allows plotting the OC-equivalent pO2 graph for PSCR
dives. This happens in both the cases where there is no external
O2-monitoring AND when there is external pO2 monitoring. The
calculations are only done for PSCR dives and is achieved as
follows:

1) Within plot-info create a pressure-t called OC_pO2 in
   profile.h and populate this variable with the open-circuit
   pO2 values in profile.c.
2) Create a new partialPressureGasItem ocpo2GasItem in
   profilewidget2.h and, in profilewidget2.cpp, initialise it
   to read the plot-info OC_pO2 values and enable its
   display by using the setVisible method. The
   diveplotdatamodel was also touched in order to achieve
   this.
3) Create a pref button that controls the display of OC-pO2 for SCR dives
4) Change the colour of the OC-pO2 grpah to orange
5) Change the connection of the crr_OC_pO2 signal to be appropriate
6) rename the OC_pO2 attribute to scr_OC-pO2

7fa5fcfa1d Don't show cylinder pressures for other dive computers
Stefan Fuchs points out that sometimes you get cylinder duplication when
you merge dives, particularly with a planned dive.  For example, if we
had different manual pressures in the two different dives, the cylinders
will be kept separate.

But that also means that we don't want to plot the pressures from those
other cylinders that came from another dive and are now associated with
another dive computer.

Change the "seen" logic for the cylinder to ignore cylinders that are
only mentioned by other dive computers than the active one.

slower the final ascent won't lead to a longer final stop.
