this gains about 20k of RAM, and has almost no impact on log download
speed at 921600 on a F427. The improved threading means we can afford
to have smaller buffers
refactor rcout into separate thread and process all dshot requests there
move uart DMA completion to event model
process dshot locks in strick reverse order when unlocking
convert Shared_DMA to use mutexes
move UART transmit to a thread-per-uart
do blocking UART DMA transactions
do blocking dshot DMA transactions
trim stack sizes
cancel dma transactions on dshot when timeout occurs
support contention stats on blocking locking
move thread supression into chibios_hwdef.py
invalidate DMA bounce buffer correctly
separate UART initialisation into two halves
cleanup UART transaction timeouts
add @SYS/uarts.txt
move half-duplex handling to TX thread
correct thread statistics after use of ExpandingString
set unbuffered TX thread priority owner + 1
correctly unlock serial_led_send()
don't share IMU RX on KakuteF7Mini
observe dshot pulse time more accurately.
set TRBUFF bit for UART DMA transfers
deal with UART DMA timeouts correctly
don't deadlock on reverse ordered DMA locks
change PORT_INT_REQUIRED_STACK to 128
calculate DMAR pulse times correctly
ensure 50us pulse separation for LED
make sure the LEDs are signalled for output
only allow LED length to be set once
treat VTX frequency as a first class citizen, match band/channel to frequency
update CRSF to use new VTX configuration
use a 6-position switch to control VTX power
add support for VTX GCS announcement
announce VTX updates on CRSF
support pitmode-until-arm and pitmode-on-disarm

set the VTX parameters to what was actually configured by the VTX
use change band/change frequency when appropriate
set power levels appropriately for protocol version.
