As per request from users on scubaforum.com, this adds
the current gradient factor to the deco information of
the infobox. Up to now, this information was only
graphically represented in the pressure bar graph
and the heatmap. This gives a numerical value.

The code seemed to do something really reasonable by picking one of the
supported OSTC versions - except that the one it picked didn't support
BT/BLE and therefore our logic of recognizing dive computers on iOS
failed.

The way this was accessed via Qt's model semantics was horrible.
This gives arguably more readable code, since we don't have to

Split out the actual filtering from the MultiFilterSortModel.
Create a DiveFilter class that does the actual filtering.
Currently, mobile and desktop have their own version of this
class, though ultimately we may want to merge them.
The idea here is that the trip-model and undo-commands have
direct access to the filter-function and thus can take care
of keeping track of the number of shown dives, etc.

The filter-model was catching dives-added / dives-deleted signals
from the models to keep track of the number of shown dives.
To simplify the data flow, do this directly in the undo-command.

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.

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.

The tab was crashing if there were no cylinders because
1) per_cylinder_mean_depth() would access non-existing cylinders.
2) TabDiveInformation::updateProfile() would access a non-existing
mean.

actually has cylinders.

Most callers of this function accessed the newly generated cylinder
immediately after calling this function. Thus, for convenience,
return the added cylinder. This avoids a number of verbose expressions.
On the flip side, cylinder_start() now has to be cast to
function returning void in a the "nesting" function table.

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.

merge_cylinders() used three bitmaps to identify cylinders used in

When calculating per-cylinder mean depths, bitfields were used to

To calculate sac rates, an array of used gases for every point on the
profile was used. This was implemented using unsigned int bitfields.
While nobody sane will ever use 32 or even 64 cylinders, for consistency

allocated arrays.
But allocate only once per shown profile, not once per sample.

All accesses to the pressure data were converted to use functions.
Therefore it is now rather trivial to dynamically allocate the
pressure array and just change the functions.
The only thing to take care of is the idiosyncratic memory

appropriate places.

get_gas_used() returns the volume of used gases. Currently,
an array with MAX_CYLINDERS is passed in. If we want to make the
number of cylinders dynamic, the function must use an arbitrarilly

in the caller.

When displaying segment or stop times in the planner notes, we always
round to the next full minute. This can mean for example that we
round down more often than rounding up with the result that the sum
of the segment times does not match the total runtime and can for example
lead to stops that are shown with 0min duration.
With this patch, we increase the reference time of the last display only
by the duration time actually shown. This way, the rounding errors don't
accumulate but having rounded down previously makes rounding up the next
time more propable.

The native buffer of a membuffer is not NUL-terminated, so when you want
to detach it and use it as a C string, you had to first do
'mb_cstring()' that adds the proper termination/
This was all documented in the header files, and all but two users did
it correctly.
But there were those two users, and the exported interface was
unnecessarily hard to use. We do want the "just detach the raw buffer"
internally in the membuffer code, but let's not make the exported
interface be that hard to use.
So this switches the exported interface to be 'detach_cstring()', which
does that 'mb_cstring()' for you, and avoids the possibility that you'd
use a non-terminated memory buffer as a C string.
The old 'detach_buffer()' is now purely the internal membuffer
implementation, and not used by others.
