Andrew Tridgell 52169f25da HAL_ChibiOS: replace volatile bools with mutexes 
this replaces the two booleans used to mediate TX and RX buffer
protection with mutexes.

The booleans were a hangover from the very early HAL_ChibiOS code, and
can lead to a deadlock. The sequence is as follows:

 - a very high CAN bus bandwidth usage, triggered by MissionPlanner
   requesting CAN_FORWARD on a CAN serial port. That causes a
   "infinite" number of CAN_FRAME messages which saturates the bus,
   and leads to the DroneCAN thread looping with no pause

 - a serial port configured as GPS type AUTO, auto-probing for a GPS
   that isn't there. This calls begin() periodically

 - the UART TX thread assocated with that UART not making progress as
   the TX thread priority is below the DroneCAN thread priority

 - this causes the begin() in main thread waiting for _in_tx_timer to
   loop forever, which triggers a watchdog
