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.

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.

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.

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.

The LocationInformationModel used to sort its entries and was completely
rebuilt after every change. This makes it rather complex to support
incremental changes.
Instead, keep LocationInformationModel sorted by UUID so that indexes
are consistent with indices in the core dive site table.
Implement sorting by other columns than name and enable sorting in the
dive site view.
Finally, don't cache the list of dive site names for the mobile app,
since that would also need some rather convoluted methods of keeping
the list up to date. Calculate it on the fly.

Since the UUID will be overwritten on save and is only used on save

As opposed to dive trips, dive sites were always directly added
to the global table, even on import. Instead, parse the divesites
into a distinct table and merge them on import.
Currently, this does not do any merging of dive sites, i.e. dive
sites are considered as either equal or different. Nevertheless,
merging of data should be rather easy to implement and simply
follow the code of the dive merging.

printGPSCoords() returned a newly allocated C-style string. Most
callers simply made a QString out of it and freed the C-style string.
This is paradoxical, as printGPSCoords internally works with QStrings
and converts them to C-style on return.
Therefore, let printGPSCoords() return a QString and create a
printGPSCoordsC() wrapper for the two C-callers.

The printGPSCoords() function returns a copied C-style string. Since
the owndership is transferred to the caller, the correct return type
is "char *" instead of "const char *".
Thus a number of casts when calling free can be removed.
Moreover a number of callers didn't free the string and thus were
leaking memory. Fix them. Ultimately we might want two versions
of the function: one for QString, one for C-style strings.

Moreover, since now the trip creation is done at the import step
rather than the download step, the latest status of the "add to
new trip" checkbox will be considered.
