789eb2c620 profile: clear plot_info structure when freeing data
free_plot_info_data() frees the sample and pressure arrays
and accordingly sets the corresponding pointers to NULL.

However, it doesn't clear the element-count and thus leaves
the structure in an inconsistent state.

Clear the whole structure with memset(). I am not a fan of
doing so, but there are existing memset() calls in the
same source file, so let's keep it like that for consistency.

24cf6709e3 profile: simplify get_maxtime()
This function has accumulated quite some cruft. It seems to add
additional space to make place for certain chart features
(e.g. the average depth text item).

However, it makes no sense to solve this here, as only the
profile knows how much place is needed to display these
features.

Therefore, basically revert this to the original version,
which simply returns the maximum time for long dives
and a threshhold for short dives that depends on the
zoomed_plot setting.

The result looks more reasonable to me, as there is no
(varying!) empty space to the right of the profile.

9fd531dcc5 Round gas depth properly
The D in MOD, EAD, END, and EADD stands for "depth" and
as such these should be mm in int rather than double.

The intermediate fn2 and fhe2, however, as intermediate
value should not be rounded to an integer.

The upshot of this is a litle more numerical stability.
It should lead to more stable values in TestProfile
when run on architectures with different floating
point precision.

7e6d9935f1 core: fix off-by-one causing incorrect profile display
In commit 4724c88 get_plot_details_new was updated to pass an index
instead of the entry into plot_string. This means we are passing "i" to
plot_string after the final increment of the for loop, instead of
getting the entry[i] within the loop before the final increment. This
means if we are mousing over the far right of the graph, where the time
based break is not hit, we will end up passing an index equal to nr-2
instead of nr-3, which is intended to shave off the final two rows
containing data not useful to the display.

There are a handful of ways to fix this. This commit intends to be
consistent with stylistic choices made elsewhere in the project.

7e11a35371 core: add a special NO_SENSOR value for sample::sensor
The sensor member of sample refers to a cylinder from which
the pressure was read. However, some dives don't even have
a cylinder. Therefore, introduce a special NO_SENSOR value
for these dives. Since the cylinder is given as a uint8_t,
0xff seems to be a sensible choice.

d0494beb5f planner: fix deco calculation
In 9bfc6d252, testing of the planner was changed to use the
planner_ds parameter instead of a global variable.

Unfortunately, two conditionals were inverted, leading to
an erroneous ceiling calculation when in the planner.

Restore the proper conditions. Moreover, instead of testing
the planner_ds parameter, use the already existing in_planner
flag, which is derived from said parameter.

To remove reliance on global state, pass an "in_planner" argument

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.

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.

Instead of accessing the cylinder table directly, use the get_cylinder()

the function does bound checking. This is crucial for now as the code

silent data-corruption that is sometimes not even noticed by
valgrind. Returning NULL instead of an invalid pointer will make

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.

A very scary proposition: You can never have two plot datas at

example subtitles.

The only reason why this didn't lead to very crazy behavior
is that at least on my Linux machine, the calloc() call would
just return the previously freed memory.
