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.

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
in the mobile interface, which doesn't use the cylinder data.
Let's not generate unnecessary CylinderObjectHelpers in this
case!
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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.

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.

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.

But don't show our cloud storage entry (as that is already in the File menu,
anyway).
This is extremely useful because while you can manually enter a file name to
save to (and therefore can use the 'magic' git repo syntax), on most OSs there
is no way to enter that non-existing 'file name' (which is the git branch in
square brackets) in the file open dialog.

When removing the max-weightsystem restriction, the semantics of

There are reported crashes on Android that suggest a null
"tables" attribute in DownloadDCThread. This should never
happen, as the table() function connected to this attribute
returns the address of a subobject. Thus, even if the original
DownloadThread is null, this would not return a null pointer
(the subobject is not at address 0).
Catch these null-object accesses and write a warning message
to the console. Hopefully, this will help is localizing the
problem.

There have been crash reports in DiveSiteSortedModel::allSiteNames().
The only conceivable reason that this crashes is that the core knows
about more sites than the model and therefore on mapToSource() we
get an invalid index, which is translated to -1. Accessing the name
of that dive site will crash.
Handle such invalid indexes gracefully.

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.
