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.

Replace a macro calculating a degree-three polynomial by an
inline function.
Moreover, calculate the powers 1, 2 and 3 of the pressure inside
the function. The compiler will be smart enough to optimize this
to the same code. The only important thing is to write "x*x*x*coeff"
instead of "coeff*x*x*x". The compiler can't optimize the latter
because ... wonderful floating point semantics.

The planner can produce negative cylinder pressures when
more gas is used than available. Let's color the pressure
graph in a highly visible color to alert the user of the
fact that current gas planning is insufficient.
Signed-off-by: Robert C. Helling <helling@atdotde.de>
The curve fitting for our gas compressibility was only done in the sane
range of 0-500 bar, which is what a scuba cylinder can reasonably be
expected to perhaps have.
But the planner ends up happily using negative cylinder pressures when
you run out of gas, and then the compressibility gives nonsensical
results.
That's clearly a planner bug, but the nonsensical gas compressibility
values made it harder to see what could be wrong.
So we just clamp the inpot range to the range we have verified against
experimental data. If you try to get compressibility for negative
pressures, you get the compressibility for an ideal and imaginary gas.
And if you try to get compressibility for pressures over 500 bar, we'll
just assume that it's 500 bar.

The git parser was using a number of global static variables. Remove
them by introducing a parser state, which is passed down to the
call hierarchy.
Advantages:
1) Removes global variables and makes the parser (mostly) reentrant.
2) More flexible - e.g. when parsing samples, the parser can now
access the dive to check if the cylinder number is valid.
3) Less weak typing through "void *".

copy_cylinders() copied the cylinders of one dive onto another dive
and then reset to the original gas values. Presumably, when copy and
pasting cylinders from one dive to another, only the types should
be copied, not the gases.
Moreover, the function could either copy all or only the used cylinders.
Firstly, the code was bogus: when restoring the pressures the indices
were mixed up: the old indices were used. Thus, when there where
uncopied cylinders, not all pressure values were restored.
Secondly, it is not clear that all callers actually want to restore
the pressure data. It rather appears the two (out of three) callers
actually just want to copy the cylinders.
Therefore, split the function in
1) copy_cylinders(): copy the cylinders with pressure data
2) copy_cylinder_types(): copy only the cylinder information
Since there is only one caller of copy_cylinder_types(), the "used_only"
argument can be removed. Since all cylinders are copied there is
no point in storing the pressure data. Don't overwrite it in
the first place.
The resulting two functions should be distinctly easier to understand.

The parsers / downloaders parse into a separate table and do
not directly change the divelist. Therefore, they shouldn't
call mark_divelist_changed().
Likewise split_dive_at() doesn't modify the dive list and
therefore shouldn't call this function.
Calling the function has the unwanted side-effect that undoing
the change will not clear the *-symbol in the title of the
main window.

Replace the fixed-size weightsystem table by a dynamically
relocated table. Reuse the table-macros used in other parts
of the code.
The table stores weightsystem entries, not pointers to
weightsystems. Thus, ownership of the description string is
taken when adding a weightsystem. An extra function adds
a cloned weightsystem at the end of the table.

While testing the cylinder type saving fix, I noticed that the RBT
saving was broken. Instead of saving RBT whenever it changed, we'd save
it when it was non-zero. Which doesn't match the git save format, and
also doesn't match what we do when loading an xml file (where we default
to the previous RBT value, and a sample RBT will modify it).

Steve Williams reported a crash when saving a previously loaded dive as

It turns out that if we can't parse the cylinder use type (OC, diluent,
oxygen, unused) we initialize the cylinder use to an invalid type, and
then when we save it, we mess up.
Fix it up by doing proper limit checking before accessing the
"cylinderuse_text[]" array when saving.

There was a global variable last_pi_entry_new, which stored the

was generated.
A very scary proposition: You can never have two plot datas at
the same time! But exactly that happens when you export for
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.
Fix this mess by removing the global variable and freeing the
data in the callers.
