526595644f Use SSRF_CUSTOM_IO v2 to implement device data quirks for BLE GATT
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.

57753321b0 Ensure all found BLE services are tracked
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.

196adb591b Very early and likely quite broken BLE GATT code
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.
