And this way we don't have to deal with the memory returned, either.

Free resources allocated by alloc_dive() with free_dive().
Don't allocate and re-allocate a fixed two byte buffer on the heap.

While this is debatably correct, free will happily accept (and ignore
the NULL pointer), so let's just always call it and make Coverity happy.

The divesEdited signal sends the changed field as a parameter.
Since some undo-commands change multiple fields, this led to
numerous signals for a single command. This in turn would lead
to multiple profile-reloads and statistic recalculations.
Therefore, turn the enum into a bitfield. For simplicity,
provide a constructor that takes classical flags and turns
them into the bitfield. This is necessary because C-style
named initialization is only supported on C++20 onward!
Is this somewhat overengineered? Yes, maybe.

The undo system sets updates individual dive fields on
redo respectively undo. Make salinity such a field, since
it is changed on replanning a dive.
To do this, break out the "update salinity" functionality
into its own function, add an entry to the DiveField enum
and add the corresponding switch-case.

We don't have the "show all dive computers" logic on mobile, so we need

Possibly we should use the libdivecomputer matching code if it exists,

The old server certificates where not recognized on some older platform,
so we hardcoded the hex digest of the valid certificate and ignored the

Those certificates have been replaced last week, so there is no point to

in verbose mode.

The DiveImportedModel and DownloadThread used the same table
of dives and dive sites. This made it very hard to keep the
model consistent: Every modification of the download thread
would make the model inconsistent and could lead to memory
corruption owing to dangling pointers.
Therefore, keep a copy in the model. When updating the model,
use move-semantics, i.e. move the data and reset the tables
of the thread to zero elements.
Since the DiveImportedModel and the DownloadThread are very
tightly integrated, remove the accessor-functions of the
dive and dive-site tables. They fulfilled no purpose
whatsoever as they gave the same access-rights as a public
field.

The way we handle singletons in QML, QML insists on allocating the
objects. This leads to a very idiosyncratic way of handling
singletons: The global instance pointer is set in the constructor.
Unify all these by implementing a "SillySingleton" template. All
of the weird singleton-classes can derive from this template and
don't have to bother with reimplementing the instance() function
with all the safety-checks, etc.
This serves firstly as documentation but also improves debugging
as we will now see wanted and unwanted creation and destruction
of these weird singletons.

When exporting dive sites, the dive sites to be selected were collected
in the C-core. But that doesn't have access to the selected dive sites
if in dive site mode. Therefore, collect the dive sites in C++ and
pass down to the core. Use a std::vector to avoid memory management
woes.

is_dive_site_used() had a "selected" parameter. If true it would
return whether the given dive site had a selected dive. Turns
out all callers had this parameter set to true. Therefore, replace
by a simplified function without the "selected" parameter and
give the function an appropriate name.

The cylindersObject list was only used by grantlee but not by
the mobile code. Since it is quite heavy, split it out and thus
don't generate it for every dive on mobile.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
Instead of handing a reference-to-dive to QML, prerender all the needed
properties and store them as values in DiveObjectHelper. Exception:
- date(): generated from timestamp
- time(): generated from timestamp
- cylinderList(): does not depend on dive anyway and should be made
static.
This hopefully avoids the random mobile crashes that we are seeing.
Clearly, this code needs to be optimized, but it is a start.

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.
