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 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

So this switches the exported interface to be 'detach_cstring()', which

In the previous commit, we just continued downloading dives when
download errors happened, but that also makes problems a lot easier to
miss because now they are possibly just transient reports in the
progress bar that get overwritten by the next dive being downloaded.
So this turns a number of these errors from using 'dev_info()' to use a
new 'download_error()' reporting model, which then uses the generic
subsurface error reporting functionality that is sticky and can handle
multiple errors.
It also adds a few 'dev_info()' calls for actual informational messages
about the state of downloading, although the new ones will probably
mainly end up happening before the progress bar is actually shown. But
it might improve on some of the progress messages.

corrupt and fails to parse:
ERROR: Buffer overflow detected! [in /win/subsurface/libdivecomputer/src/hw_ostc_parser.c:981 (hw_ostc_parser_samples_foreach)]
Subsurface (incorrectly) considers that a fatal error and stops the
entire download. From a user point of view, it would be much better to
ignore the problematic dive, and continue downloading the remaining"
Subsurface used to just stop downloading if there were parsing errors,
but Jef further says:
"How parser errors are handled is up to the application. Aborting the
download is probably the worst option here. If a dive fails to parse
(because the dive data is corrupt, the parser contains a bug, etc),
that does not necessary mean the remaining dives can't be downloaded"
so let's change the logic to just continue downloading, and hope other
dives work better.
We might want to do better error reporting, right now the errors tend to
just cause "dev_info()" reports, which just set the progress bar text.
So you'll see it in the progress bar as it happens, but it won't get
really ever noted as an error, and it's easy to miss.
But that error reporting is a separate issue, and this just does the
"continue to the next dive" part.

than the five parameter fit using a fourth order
polynomial.
Fitting the log has the advantage that this never
crosses 0, which would have the bad effect of
resulting in negative CNS values as we divide
by the table value.
We don't adopt a maximum pO2 cut-off for the CNS calculation
but rather live with the large values that the interpolation
formula produces when extrapolating.

It turns out that the dive site saving was subtly but horribly buggy.
To save the value of the dive site, it did
show_utf8_blanked(b, t->value, " value='", "'/>\n", 1, anonymize);
which looks sane on the face of it, but the problem is that it puts the
final closing xml marker in the 'append this at the end' case.
That means that if the value is empty, the value won't be saved, but
neither will the closing tag. Resulting in an xml line that looks like
this:
<geo cat='3' origin='0' <geo cat='5' origin='0' value='Other name'/>
where the first geo tag was saved without the ending marker.
That then makes all the xml nesting entirely wrong, and the whole file
fails to save.
Now, the code around it does check that 't->value' is not NULL, but it
doesn't check for a value that is empty or all spaces (which also will
make 'show_utf8()' just skip it.
Fix it by saving the end marker separately:
show_utf8_blanked(b, t->value, " value='", "'", 1, anonymize);
put_format(b, "/>\n");
so that the xml is valid even if the goe marker value wasn'r.

When removing the max-weightsystem restriction, the semantics of

to 0 or 1 weightsystems, because the mobile frontend uses this

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.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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
