We certainly should log errors and the complete list of discovered
devices.
Also, it's good practice to set a specific search time (I picked three
minutes). This way we won't constantly scan and drain resources.

We call the same helper from two spots. Once when we report the already
paired BT devices on Android, and once from the deviceDescovered signal
for the discovery agent. Let's make sure we can tell where the info came
from.

There is no need to continue to look, and at least with the Shearwater
Peregrine having the scan run while we are trying to discover characteristics
appeared to cause issues.

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.

And offer an option to show all devices in the settings. This is intentionally
not stored in the preferences as this should never be needed. We don't support
BT or BLE dive computers that we don't recognize. This is a last resort in case
a new firmware were to change the name or some other weird issue causes us not
to recognize a dive computer - and that should be fixed instead of worked
around.

By default we'll only show devices that we believe to be dive computers,
but the user can override that with the recently introduced check box.

Each callsite of saveBtDeviceInfo() has a QString, which is converted
to a C-string, passed and immediately converted back. Remove these
conversions by taking a reference to QString directly.
getBtDeviceInfo() is not as clear. Here, the callsite has a C-string
handed down from libdivecomputer. Nevertheless, pass a reference of
QString here as well. Firstly, for reasons of symmetry. Secondly,
to avoid multiple conversions in the getBtDeviceInfo() functions.

This commit implements possible switching BT on and off during a session,
so not needing a restart of the app when the user forgot to switch
it on when starting the app.
For this, the following needed to be done: 1) create a handler that
reacts on local BT device status changes. 2) repopulate the connection
list in the download screen when a BT status change is detected.
Notice the subtile change of the Q_INVOKABLE btEnabled() function
to a Q_PROPERTY. This gives a nice dynamic behaviour when
switching BT on/off with the app open.
Fixes: #556

Right now this will only work if you scan for your BLE dive computer every
time. Ideally we should simply initiate a scan and look for that address if
it's not found in the hash.

This should be much more robust in getting us the correct Bluetooth address
and the correct vendor / product for our selection.
When we pick a paired device, we extract the address right from its name.

Major functional change in this commit is the addition of found static BT devices
to the internal administration (on Android), in a way that is equivalent to
mobile-on-desktop. So, in both cases, the list of devices in the app are
as in the list of devices on the host OS (Linux or Android). To minimize code
duplication, the btDeviceDiscovered slot is split in two parts, the part to
act as slot for the Qt BT discovery agent (Linux, so mobile-on-desktop), and
the part only needed for Android.
Remaining to be fixed: the correct handling of the QML UI selection of
vendor/product. The first default dive computer is correctly detected,
all paired devices from the virtual vendow can be selected, but clicking
through vendors results in non logical selections. It is obvious why
this is, but a fix is not straigforward at this point.

This adds a central function to convert a BT name to a vendor/product pair
known to Subsurface. This allows interfacing from a paired BT dive
computer, without actively selecting its type, but by selecting it
from the list of paired BT devices. So, after this, downloading from
multiple (paired) DCs is also possible.
And not the niced piece of code ...

Added a list of paired BT devices for the "Paired BT Devices" vendor. The
devices under this vendor represent all BT devces that can be found
from the local BT interface. Some special processing is required, as
the BT provided data is (obviously) missing the specific data needed
to open a BT device using libdc code. This processing is not in
this commit, but will follow. This commit is preparation for that.
