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.

Even though the returned dive is not const, the table is not
changed, as it only contains pointers.

The plan is to make the model the authoritative source of
the imported dives. Therefore, access the number of
downloaded dives from there.

When importing dives, consume the tables from DiveImportedModel
and not the DownloadThread. This appears more logical and avoids
an inconsistent state of the DiveImportedModel: On import the
tables would be reset, but the DiveImportedModel wasn't
informed of that.

In DownloadFromDCWidget::on_ok_clicked() deselected dives were
directly deleted from the dive table, leaving DiveImportedModel
in an inconsistent state. Use the function in DiveImportedModel
instead. This also removes code duplication.

In DiveImportedModel::deleteDeselected(), unselected dives were
deleted from the dive-table. But this left the model in an
inconsistent state and the frontend was not informed of the
missing dives.
Fix this by invoking the appropriate beginRemoveRows()/
endRemoveRows() pairs. Move the functionality into its
own function so that it can be reused by the desktop version.

Currently, desktop and mobile are accessing the DownloadThread
and the DiveImportedModel concurrently. This makes a big data
flow mess. To achieve a more hierarchical data flow, start
by making the DownloadThread a subobject of DiveImportedModel.
Start the download by calling a function in DiveImportedModel.
Route the finished signal through DiveImportedModel. Thus,
the model can reload itself with the new data.

To allow efficient moving of downloaded dives from the download
thread to the model, implement a general move function that
moves table data. Instantiate that function for the dive and
dive_site tables.

Owing to apparent QML breakage, a model-reset leads to the DiveDetail
page being reloaded for every dive in the list(!). Therefore, add
rows instead.
This leads to extremely subtle code, as it is now imperative that
the model has been properly cleared beforehand. Nevertheless, for
now we have to do this to fix a severe performance regression.

Instead of using the GpsLocation singleton in GpsListModel::update()
to extract the gpsTrackers, pass the gpsTrackers as function argument.
The caller has direct access to the GpsLocation object anyway and this
make things less entangled.

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 building dbus within the appimage, cmake picks up the installation
path of various files dbus uses through the GNUInstallDirs package,
however this doesn't work under the appimage build.
So we replace the variable with the normal location of this file.

Instead of converting the section-heading string to a trip-pointer
in QML and pass that to the tripTitle() and tripShortDate()
functions, pass the string and convert in C++ code.
Hopefully, this makes the code more robust.

The section heading in the QtQuick ListView has to be a string.
Therefore, we passed a pointer formatted using hexadecimal notation.
Later, that was converted back without being checked.
A very scary proposition, so let's pass unique integer trip-id instead.
This means that on converting back we have to scan the trip table,
but that is a very minor cost comsidering to the gained robustness.

To make it easier to pass around trips through QML, give each trip
a unique id. The id is generated in alloc_trip() and uses the same

is_dive_site_used() had a "selected" parameter. If true it would
