The current "select the correct BLE service to talk to" is flawed.
It assumes that the first found non-standard UUID is the right one
and apparently it is for some DCs. But not for the HW devices.
The HW devices use a "standard" ie. approved by the Bluetooth
SIG, controller, that comes with a UUID that our code currently
considers standard so not to be the right one.
This (simple) commit selects the right service for HW. The UUID
is hard coded, and this is ok, because it is tied to the hardware
used by HW. Futher, it does not change anything for other BLE
devices.

This initalizes the Terminal I/O client as described in paragraph 3 of
http://www.telit.com/fileadmin/user_upload/products/Downloads/sr-rf/BlueMod/TIO_Implementation_Guide_r04.pdf
This is for all Heinrichs Weikamp computers, that use referenced BT/BLE hardware
module from Telit Wireless Solutions (Formerly Stollmann E+V GmbH). The 16 bit
UUID 0xFEFB (or a derived 128 bit UUID starting with 0x0000FEFB is a
clear indication that the OSTC is equipped with this BT/BLE hardware.
Furthermore, most devices equipped with this BT/BLE hardware have BT addresses
starting with 00:80:25:...

This seems really long, but one user appeared to get a response after
almost 10 seconds. So going with 12 for some margin of error.

Right now we have a quirk for Shearwater devices to set the random
address flag, but also to handle the differences at read/write time.
With this, I can finally download from both the Suunto EON Steel and the
Shearwater Perdix AI with the same binary.
It's not *pretty*, but it works.

We rather use wait in combination with spinning the event loop.

If a device has more than one service the order of service discovery
determined the selection of the service that we intend to interact
with. This assumption is not accurate and is even platform dependent.
Thinking ahead, it is likely that some devices may require us to keep
track and interact with multiple services at the time.
The new logic still suffers from the fact that there is no way
to select the correct service for interaction. This will require
higher level stack changes.

toUtf8() creates a temporary char* representation which is assigned to
uuid. As soon the object created by toUtf8() gets destroyed, the uuid
pointer points to releases memory.
The intention is to check that we don't have one of the standard
16bit Bluetooth uuids. That's the purpose of QBluetoothUuid::toUInt16().

This seems a bit odd, but it actually has three different reasons for it:
- It's a visual indication of BT LE mode for users
- the rfcomm code only works with legacy BT support, and if we scan a
device that only does LE, we want the custom serial code to instead
automatically fall back on a "emulate serial over LE packets" model.
- we want rfcomm to remain the default for devices that do both legacy
BT _and_ LE, but we want people to have the ability to override the
choice manually. They can now do so by just editing the address
field and adding the "LE:" prefix manually, and it automatically gets
saved for next time.
So while a bit hacky, it's actually a very convenient model that not
only works automatically, but allows the manual override.

This is some very early and hacky code to be able to access BLE-enabled
dive computers that use the GATT protocol to send packets back and forth
(which seems to be pretty much all of them: a vendor-specific GATT
service with a write characteristic and a notification characteristic
for reading).
For testing only. But it does successfully let me download dives from
my EON Steel and my Scubapro G2.
NOTE! There are several very hacky pieces in here, including just
"knowing" that the write characteristic is the first one, and the
notification characteristic is second. The code should actually check
the properties rather than have those kinds of hardcoded assumptions.
It also checks "vendor specific" by looking at the UUID string
representation, and knowing that the standard ones start with zero.
Crazily, there doesn't seem to be any normal way to test for this,
although I guess that maybe the uuid.minimumSize() function could be
used.
There are other nasty corners. Don't complain, send me patches.
