Instead of keeping track of a list of DiveObjectHelpers, generate
them on-the-fly in DiveListModel. Thus, there is less danger of
model and core getting out of sync. On the flip-side, now the
DiveListModel and the DiveListSortModel might get out of sync.

DiveObjectHelper is a tiny wrapper around dive * to allow access
to dive data from QML and grantlee. It doesn't have to be a
full-fledged QObject with support for signals, etc. Therefore,
turn it into a Q_GADGET based object. This allows us passing the
object around as object, not as pointer to DiveObjectHelper.
This makes memory-management distinctly easier.

The canonical way of displaying lists in Qt is via models.
Thus, return the tripId directly from the DiveListModel instead
of going indirectly via a DiveObjectHelper. In the future, this
will allow us to make the DiveObjectHelper value-based, as it
is not generated numerous times for every list item.

These properties are not needed anymore, because the full text search
was decoupled from the DiveObjectHelper.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
1) The full text search was looping over the DiveListModel when
it could simply loop over the core model. Do that instead.
2) Don't generate a DiveObjectHelper to do a full text search.
Currently this is harmless as the DiveObjectHelper is only
a disguised "dive *". But from a conceptual point of view,
it represents the full representation of a dive and we don't
want to generate that in a tight loop.
This will help in
1) Making the DiveObjectHelper a non-reference object.
2) Moving fulltext search to the core and thus making it available
to desktop and more performant.

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.

Eric Charbonnier reported a problem downloading the dives from his
OSTC2, and Jef debugged the libdivecomputer log and says:
"Your ostc has 75 dives, but subsurface downloaded only one, and then
stopped the download. That's because that first dive appears to be
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.

Therefore has been effectively dead code.
Reimplement the functionality, but be more robust by considering

string in two parts, before and after the "%s" place-holder.
Search for these two parts. Remove the disclaimer and everything

Therefore, introduce a init_plot_info() function and call that when

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 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.

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.

The planner can produce negative cylinder pressures when

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.
