The current BLE read reads just one 20 bype packet. That packet size is set
in ble_serial_ops, so, without being able to test on anything other than
a OSTC3, I assume that this holds for other BLE DCs too. So, I think is
is weird that those interfaces work with the current read() of just one
packet at the time.
As we need a blocking read (at least for the OSTC parser), just read all
data that is available on the input. And when we think we are done, give
the QtEventloop control to see if there is more, and process that incoming
data as well. All this basically implements a blocking read.
CAVEAT 1: This might break the reading from the currently working BLE devices.
CAVEAT 2: With this, I still cannot read the OSTC3 completely. For
developers familiar with the HW transfer protocol: it just stops while
reading the first full dive (header + profile) command 0x66, despite
correctly reading about 5Kb of data before. For some
reason, I do not believe that this is related to this commit.
CAVEAT 3: All above tested on Linux Desktop with bluez stack, and
confirmed NOT to work on Android 7.1.2, build with Qt 5.9.0, And
yes, I know 5.9.1 recommended.

1) As the OSTC sends data to the BLE central role (the SSRF client) over 2
characteristics, we have to filter the administrative credit data from
the actual dive data that it received. The characteristcStateChanged
function is adapted for this.
2) We have to be sure that the Terminal Client I/O is fully defined during
opening the connecton to the OSTC. From 6d505b24f0c15 we can see
that the last step in setting up the terminal interface is the grant
of credits. This is done by writing to the proper (the only one, with
id = 0x2902) descriptor of the credits RX characteristic. The here
added slot is triggered on the completion of write of credits marking
the final stage of the setup.

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.

For DCs that support both BT and LE, allow the user to connect to both
interface layers. Maybe not usefull in the end (as BT is faster
than LE), but as long as BT on Android is WIP is it very useful
to be able to connect to the interface layer we like.
Just add it to the Paired Devices list twice. The normal way, and
the LE: prepend way.

Using the Homebrew dependencies is much easier and faster, but then

Latest Kirigami master allows us to turn off reachability mode. In
general this had been rather confusing to our users and it seems to
somewhat conflict with the pull down to refresh of the dive list.
Latest Kirigami also changes the behavior of refresh slightly, you now
need to pull "down" for at least 500ms before it triggers. So, with this
change and the latest Kirigami, hopefully the user experience for
refresh is good enough that we can consider keeping it enabled and use
it as an equivalent to manual sync (even in offline mode).

Fast flicking to the top of the divelist triggers almost certainly a
pull down sync, as the default boundBehavior is DragAndOvershootBounds.
Despite being the default QML action, this leads to unwanted pull
down syncs (even in offline mode).
Setting the boundBehavior to DragOverBounds solves this issue. Now,
the user has to explicitly drag the top down to force a pull down
sync, and a accidental fast flick is stopped at the upper bound.

I hate changing the IO interfaces this often, but when I converted the
custom serial interface to the more generic custom IO interface, I
intentionally left the legacy serial operations alone, because I didn't
want to change something I didn't care about.
But it turns out that leaving them with the old calling convention
caused extra problems when converting the bluetooth serial code to have
the BLE GATT packet fall-back, which requires mixing two kinds of
operations.
Also, the packet_open() routine was passed a copy of the 'dc_context_t',
which makes it possible to update the 'dc_custom_io_t' field on the fly
at open time. That makes a lot of chaining operations much simpler,
since now you can chain the 'custom_io_t' at open time and then
libdivecomputer will automatically call the new routines instead of the
old ones.
That dc_context_t availability gets rid of all the
if (device && device->ops)
return device->ops->serial_xyz(..);
hackery inside the rfcomm routines - now we can just at open time do a simple
dc_context_set_custom_io(context, &ble_serial_ops);
to switch things over to the BLE version of the serial code instead.
Finally, SSRF_CUSTOM_IO v2 added an opaque "dc_user_device_t" pointer
argument to the custom_io descriptor, which gets filled in as the
custom_io is registered with the download context. Note that unlike
most opaque pointers, this one is opaque to *libdivecomputer*, and the
type is supposed to be supplied by the user.
We define the "dc_user_device_t" as our old "struct device_data_t",
making it "struct user_device_t" instead. That means that the IO
routines now get passed the device info showing what device they are
supposed to download for.
That, in turn, means that now our BLE GATT open code can take the device
type it opens for into account if it wants to. And it will want to,
since the rules for Shearwater are different from the rules for Suunto,
for example.
NOTE! Because of the interface change with libdivecomputer, this will
need a flag-day again where libdivecomputer and subsurface are updated
together. It may not be the last time, either.

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.

This is somewhat hacky, but it allows at least the Shearwater
libdivecomputer backend to continue to treat even the BLE GATT model as
just a serial protocol.
What it does is create a special "emulate serial behavior over the
packetized BLE protocol" helper layer, that qtserialbluetooth falls back
on when rfcomm is not available.
NOTE! This still requires some BLE packet code changes to work with the
odd way that Shearwater sets up their BLE GATT communication. So note
that no further patches are necessary to *libdivecomputer*, but some
updates are needed for the subsurface qt-ble.cpp code.
I have those updates in my tree, and this code is all tested on my
Perdix AI, but those patches are currently too ugly to commit as-is.
I've cleaned up this "fake serial" code sufficiently, that cleanup comes
next.
