25b30da244 Profile: properly initialize plot_info structures
The create_plot_info_new() function releases old plot data. This
can only work if the plot_info structure was initialized previously.
The ProfileWidget2 did that by a memset, but other parts of the code
did not.

Therefore, introduce a init_plot_info() function and call that when
generating a plot_info struct. Constructors would make this so much
easier - but since this is called from C, we can't use them.

Fixes #2251

d570cb789f Update libdivecomputer to support the Aqualung i200c
I got confirmation from Tiago Thedim Dias that my libdivecomputer patch
makes BLE downloading work from the i200c, and already pushed out the
libdivecomputer changes earlier.  This updates the subproject in
subsurface to have those changes.

This also adds the bluetooth name patterns for the i300c and a few other
Aqualung dive computers we hadn't added yet.  That should make them show
up in the bleutooth device list even without having to check the "Show
all bluetooth devices" check-box.

Tiago claims he didn't need that, and I wonder if we have some overly
permissive match somewhere, but it's the right thing to do regardless.

Instead of generating cylinder data in the form of
CylinderObjectHelper objects for every DiveObjectHelper,
generate it only if needed. DiveObjectHelper is used extensively

f25fa2adc5 Cleanup: turn CylinderObjectHelper into value type
CylinderObjectHelper is used for structured formatting of cylinder
values in grantlee types. Instead of keeping a reference to a
cylinder, turn it into a value type containing the formatted strings.

This should be distinctly safer, as we don't risk having stale
references flying around. Moreover, we don't have to use pointers
but can use containers containing plain CylinderObjectHelper. Thus,
no explicit memory management is needed, making the code distinctly
easier to understand.

Sadly, currently grantlee does not support Q_GADGET based Q_PROPERTY.
Therefore a GRANTLEE_*_LOOKUP block has to be added. This can be
removed in due course, as a patch to remedy this issue is in current
grantlee master.

a0912b38bd Replace table interpolation by two line fit for CNS
We used a table lookup for CNS equivalent times. Turns
out the log of this table falls pretty much on a straight
line for po2 <= 1.5bar. We now fit this tabel two two
lines, one for <= 1.5 bar and one above. This four
parameter fit has half the sum of errors squared
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.

8c408da9ab Fix the dive site XML saving
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.

00944f7a02 Core: pass dive, cylinder-id to fill_default_cylinder
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.

a8b1c86139 Limit gas compressibility argument range to halfway sane values
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.

a0cd89f850 Core: split copy_cylinders() in two functions
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.
