The trigger range/mask "compression" procedure is apparently not
required and breaks triggering on a low line state.
This has been verified to fix the issue on a Hantek 4032L with FPGA
version 0x4303. It is possible that the procedure mentioned above
might be required for other FPGA versions, though that is unknown.
If you experience trigger issues with other FPGA versions, please
contact us for further debugging and testing.
This fixes bug #1402.
- add support for multiple transfers.
- set nummber of samples to 1 for FPGA FW version 0
- increase size of data transfer buffer to 2kB.

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.

- 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.

[Note: This patch is basically a squashed version of the initial driver
commits by Andreas Zschunke <andreas.zschunke@gmx.net>, two fixes by
Andrej Valek <andy@skyrain.eu>, and various coding style / cosmetic
fixes by Uwe Hermann <uwe@hermann-uwe.de> to make the driver a lot more
consistent with the rest of the libsigrok code-base.]
