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.

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.

When gas switching only on stops is selected, the notes
showed an extra line at the not realized stop depth. This
eliminates it. It also makes sure there are no 0 second
spurious entries. And gas switching takes more than zero
time (otherwise we would have to print a line of zero
duration for at the gas switch depth).

The fill_default_cylinder() function calculated the MOD based
on the currently displayed dive. This does not seem to make sense:
- When importing dives, why would we care about the altitude and
salinity of the currently displayed dive, possibly from a different
trip.
- The planner is supposed to be thread-safe and should not touch
global variables.
Of course this means that the importing-functions have to fill
out altitude and salinity before creating the default cylinder,
but this is their problem. For a freshly created dive they will
get the default values, which still seems less random than the
values from the displayed dive.

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.

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]).

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.

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.

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.

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,

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.
