uni-t-ut32x: rephrase the receive buffer and packets relation
The previous implementation assumed that a receive data chunk ends
exactly with a sensor packet's end. Yet the buffer had 32 bytes while
the packets have 19 bytes.
Separate the data reception from the packet processing. Collect whatever
chunks the USB connection provides, and scan the resulting buffer for
packets. Cope with either incomplete or corrupt or misaligned packets as
well as with multiple packets in receive chunks. The latter might happen
upon initial synchronization, when a device already sends data or the
serial port buffered previously communicated data.
In the regular case, the computer will process so fast that each single
character will be handled individually. We don't mind. The frequency is
some 60 times per second, and the data volume is 19 bytes. The software
works for the regular case, and synchronizes fast at startup or after
comm errors.

uni-t-ut32x: improve robustness of packet parser, more diagnostics
Always print the data bytes of received buffers in the packet parser,
then check some more fixed fields to not process invalid packets, then
process the packet content as the previous implementation did.
Call the packet parser for incomplete packets and discarded input
buffers as well (initial synchronization, re-sync after comm errors).
This results in the availability of more diagnostics during development.
Pass the packet's location and size from outside. This prepares the
logic to cope with situations where the receive buffer contains multiple
(potentially incomplete) packets.

556a926d432dd introduced support for multiple displays in
subdrivers of serial-dmm, but also changed user visible channel numbers
to start from 0. Restore the previous behaviour, start counting from 1
which users may perceive as more natural (serial-dmm used to start at P1
in the past, scopes start with CH1 as well).

brymen-bm86x: avoid NULL deref when usb->devhdl does not exist
There are code paths where dev_close() tries to access a USB handle
which does not exist. This was observed with this command:

Fix read past end of array in sr_analog_si_prefix_friendly.
In the case where the input unit was not in the array, the for loop would
complete, but the following test would then read past the end of the array
since 'i' would already have been incremented to the array size.
Spotted because unitless data was getting SI prefixes with no unit, though
this would not have been deterministically reproducible.

scpi-pps: Don't block waiting for a value on capture stop.
The comment says "A requested value is certainly on the way", but the code no
longer works this way. The receive handler requests a value and blocks until
it is received. There is no value pending between receive handler calls, so
this code now only leads to a timeout.

Consistently use the _WIN32 #define.
The _WIN32 variant is available pretty much on all compilers, others
might not be. G_OS_WIN32 would probably be an equally well-suited
alternative, but for now we standardize on _WIN32.
