1a0f6f53ed undo: set dive mode to CCR in undo command, not profile code
When setting a CCR setpoint, the profile code(!) would turn
the dive into a CCR dive. Not only should the display layer
not alter dives, this also means that the action is not
undoable.

Move that to the appropriate undo command, where it makes
more sense, but obviously also makes things more complicated.

09287809eb profile: move adding of ceiling-violation-event
The profile item that shows the ceilings adds a warning event
if the ceiling is violated. This is very unfortunate.

Improve this situation by adding the event up to the function
that calculates the ceiling. This is still not how it should
be - the display layer should not modify the dive that it
displays.

To make this clear, add a comment that details that this
is a contract between planner and display layer: The planner
uses a dive that can be trampled upon by the profile.
Still, this should be solved differently.

9bfc6d2520 profile: use a parameter to determine planner state
The in_planner() function is incompatible with a reentrant
profile, since it accesses a global variable. In
create_plot_info_new() it is essentially redundant, because
there is a planner_ds (ds = deco_state) parameter that
is used only when in the planner. Therefore use that as
the in_planner indicator: when non-null, the profile is
showing a planned dive.

Since dive.c is so huge, split out divecomputer-related functions

d787e8812c profile: for maxtime calculation include the sample after the last event
When plotting profiles with surface segments, there were strange
artifacts. As we found out with Robert, these were due to the fact
that the calculated maxtime was set to the last event which is just one
second inside the surface segment. This terribly confused the profile
code. For example, it didn't properly allocate samples for the surface
segment.

Thus, when calculating maxtime, consider the last sample beyond the
last event.

b850384100 Profile: fix pressure scale
The determination of minimum pressure in calculate_max_limits_new()
in profile.c was wrong for a long time. Since the loop went over all
cylinders (even unused ones), the minimum pressure was always zero.

Since we loop only over used cylinders, the minimum pressure was
initialized to the lowest starting pressure of any cylinder.

If there were no events with pressure change, the minimum pressure
stayed unchanged, resulting in a funky scaling.

Instead, let's initialize the minimum pressure to the lowest ending
pressure.

794066b236 Cylinders: access cylinders with get_cylinder()
Instead of accessing the cylinder table directly, use the get_cylinder()
function. This gives less unwieldy expressions. But more importantly,
the function does bound checking. This is crucial for now as the code
hasn't be properly audited since the change to arbitrarily sized
cylinder tables. Accesses of invalid cylinder indexes may lead to
silent data-corruption that is sometimes not even noticed by
valgrind. Returning NULL instead of an invalid pointer will make
debugging much easier.

7c9f46acd2 Core: remove MAX_CYLINDERS restriction
Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.

Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.

One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

25b30da244 Profile: properly initialize plot_info structures
The create_plot_info_new() function releases old plot data. This
can only work if the plot_info structure was initialized previously.
The ProfileWidget2 did that by a memset, but other parts of the code

Therefore, introduce a init_plot_info() function and call that when
generating a plot_info struct. Constructors would make this so much
easier - but since this is called from C, we can't use them.

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.
