See also b409e9fc91 and 709c1df2af. The OSTC parser
cannot handle reads of single 20 byte BLE packages in serial mode.
Instead of doing a deeper down agressive read, we can read on
the serial level more subtile. As the parser is requesting a
specific number of bytes, we just read that number of bytes and
return them. As the 20 byte BLE packets do (obviously) not
align with the reading requirement of the libdc parser, a little
housekeeing needs to be done in between individual reads.
CAVEAT 1: In contradiction to 709c1df2af, this is supposed to
work for all parsers that properly specify the needed bytes to fetch.
CAVEAT 2: All above tested on Linux Desktop with bluez stack.
Subsurface mobile is step 2.

Commit 709c1df2af introduced a hard blocking read for BLE devices.
This did break BLE reads from multiple DCs, and (in hindsight) was not
a correct implementation. It would require, for example, dynamic
read buffers as especially profile data grows with dive time, and
in addition, and more importantly, also the OSTC libdc parser cannot
process the entire profile of a dive at once (but likes to receive
it in 1K blocks). So, basically, it introduced issues, and did not
solve the OSTC read.
This commit reverts this hard blocking read (and as such will break
OSTC BLE reads). But it enables removal of the special cases for
the EON Steel and G2.
A next commit will solve OSTC BLE reads.

Handle credits. Do not just ask for maximum credits all the time as this
will stop the download. Also do not let the credits go back to 0 (while
this might work, this is not tested). Getting back the 0 credits stops
the download, and even when it can be restarted, it is less efficient
(and not needed). Notice also that it takes some time before a grant
request is honoured. During testing I saw reception of up to 25 packets
between request and grant. So a lower bound for the request of
32 packets seems resonable.
One aspect the Telit/Stollmann TIO puzzeled me. Sections 4.1 and 4.2
both talk about credits, but my hyphothesis is that there are two
credits counters in play. One for traffic either way. This commit
only deals with credits granted by Subsurface to the OSTC to send
data. Credits granted by the OSTC to allow Subsurface to send new
commands is NOT part of this commit, and is seemingly not needed
in our scenario. As we only send new commands to the OSTC when
a previous one is finished (per HW's interface spec), the OSTC
does not run out of credits to receive commands.

The trick is to pick a path that is accessible from other applications.
In theory QStandardPaths::GenericDataLocation should provide that.

on the screen the user wants to see the dive computer product

This is a bit awkward with a VENDOR event - but at the time the strings
are generated, we don't have the information, yet, that we need to
determine these values (we need the last sample parsed, but the strings
are created as part of the dive headers.

In general this patch enables building of subsurface without being
forced to use the official Qt binary packages. This is particularly helpful
when having to debug Qt internals or having to deal with custom patches
on top of the official Qt releases.
The architecture dependent file path layout is only employed by official
Qt binary packages. They are the result of a reordering at package
generation time. If Qt was build for a single architecture, the standard
layout does not add the architecture specific top level patch for the resulting
binaries.

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.
