To make this class available from QMLManager, the run_ui()
function would create the object and then set a pointer in
QMLManager. It works, but is inconsistent with the rest of
the code. Therefore, make it a classical singleton class,
which is generated on demand.

GpsListModel was one of those "special" singletons that could
be created explicitly with new. This would make sense if a
parameter were passed to the constructor. We only passed null,
so one might as well turn that into a classical singleton with
default constructor.

DiveImportedModel::recordDives() called add_imported_dives(). But that
actually consumes the dive and dive-site tables. Which in turn will
lead to an inconsistent model.
Properly reset the model by using the consumeTables() function.

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.

When importing dives, consume the tables from DiveImportedModel

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.

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.

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 converting the section-heading string to a trip-pointer

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.
