Callback for data transfer is separated from status. This change will be
used for better data transfer sending/receiving. Cast signal, that trigger
has been captured was moved into state: H4032L_STATUS_FIRST_TRANSFER.

Acquisition won't work correctly in a multi-threaded environment, when
config_set() and config_get() are called with a channel group.
The channel switching itself has moved to scpi/scpi.c, to be able to
handle switching in a thread safe way.
Use of the thread safe SCPI functions, so no write+read operation is
interruped.
Also return float values instead of double value in acquisition mode.
This is related to bug #779.

Allow developers to specify the (default) number of frames at compile
time (default to "off" as before). Accept the frame limit spec at scan()
time as well. This is useful when applications don't run config_set() at
runtime.
Tested with:
$ pulseview -d demo:logic_channels=0:analog_channels=1:limit_frames=4
The previous implementation supported the generation of frames as a
compile time option. This change lets users adjust the feature at
runtime.
In the absence of a frame count limit no frame begin/end markers get
sent (the default behaviour of the previous implementation). When a
frame count limit is specified, the respective number of frames gets
sent and acquisition stops.
The fixed amount of 1000 samples per frame is an arbitrary choice. This
compile time option is easily adjusted in the source code.
Introduce support for the "graycode" logic pattern. Generate up to
64 bits of graycode output (all logic lines, no repetition, not limited
by the generator's internal pattern buffer). The implementation was
tested with 16 channels.
Keep a context variable around with a bit mask for all logic channels.
This is convenient in setup and generation routines, to avoid garbage
in unassigned bit positions of session feed packets.
Move the declaration of codes for pattern types before the declaration
of the context container such that the latter can reference the former.
Add 'int' to an unsigned variable that omitted the base type.
The initial voltage threshold in dev_open() was being set to a
default value in the devc->cur_threshold variable but not actually set
in the device itself.

- use pragma to handle different behavior between gcc and minGW bit-field packing
- bit-field integer variables needs to be align to 2-byte boundary
Compiler does not produce an error when accessing into non-__packed pointer.
However, the field might not be properly aligned for this type.

Use serial_readline in acquisition mode, otherwise data from the
Re:load Pro could get lost.
Use reloadpro_receive_data() for all commands when in acquisition
mode. When not using a single point of receiving data, data could get
lost.
Prefer sigrok's endianess conversion helper over the inet htons()
routine which is harder to read (is "network order" little or big?).
Writing the conversion results in units of bytes also avoids misaligned
memory access. The header length is odd, each payload item got written
as an uint16_t item to an odd address.
