* Initial commit of hackrf_biast
* Cleaned up hackrf_biast
* Cleaned up usage info
* Include getopt.h for non-GNU systems
* Add support for overriding HackRF's default antenna power behavior in firmware. Add support for specifying antenna power behavior in libhackrf.
* Moved bias tee config routines into user_config.c, cleaned up operation of hackrf_biast
* hackrf_biast now calls usage() and exits when invoked with no arguments
* Fixed minor documentation error in usage()
* minor syntax cleanup
* Add some documentation to the host API call
* Add proper declaration magic in hackrf.h to hackrf_set_user_bias_t_opts() to appease Visual Studio
* Documentation changes suggested by @martinling
* Moved bias t setting above switch statement, removed line that explicit turned bias t off when entering OFF mode
* Change hackrf_set_user_bias_t_opts() to use a friendly struct() instead of a bitmask. User friendliness fixes to hackrf_biast options. More clang-format appeasement.
* Removed support for integer mode args from hackrf_biast
* clang-format error fixes
* Tweaked position of comment for clang-format v14
* Reformat files with clang-format v14 instead of 16
* Remove internal numeric modes for bias T settings

This adds a `hackrf_debug [-S|--state]` option, and the necessary
plumbing to libhackrf and the M4 firmware to support it.
The USB API and libhackrf versions are bumped to reflect the changes.
Just a very rough merge to get off the ground. Major parts are not yet
implemented. The mixer intergration is in a messed up state. Part which
need work have been marked with XXX

Among the TODOs:
* Refactor obtaining LPC serial number and chip ID into separate API and header/source files. Remove from main().
* Create a usb_set_serial_number_descriptor() or similar function to be called before USB stack is started.
* Ensure USB serial number descriptor is valid even if code forgets to initialize the serial number before the USB stack is started. May be as simple as providing default initializer for usb_descriptor_string_serial_number[].
* Create a #define/constant for the usb_descriptor_string_serial_number length.
* Identify what's causing intermittent crashes in hackrf_transfer when no serial number is specified. I'm probably misusing getopt.
* Permit serial number without leading zeros so you don't have to type as much.
* Add support for serial number argument in other hackrf_* tools.
* Provide libhackrf support for enumerating multiple HackRFs, so that hackrf_info can list all devices. May require an additional libhackrf function, outside of hackrf_open().
...and anything else that makes this less of a hack.
Previously CPLD programming involved a large 64kbyte buffer into which
the the entire bitstream would be completely downloaded, and at which
point the programming process would commence. This is needlessly
wasteful of memory. Moreover, it could lead to USB timeouts as the
firmware needs to wait the entire duration of the programming process
before returning an ACK to the host after the final SETUP data phase
packet.
Instead, we now receive 512 byte chunks of the bitstream and stream them
to the CPLD one at a time. We wait for each packet to be streamed out to
the CPLD before ACKing the packet to prevent active data being
overwritten.
