LED processing on a separate thread allows much longer LED lengths to be handled without
compromising dshot timing or timeouts. The thread is also run at a lower priority to
reflect its lack of flight criticality
fixes frequency setup for neopixel, separating out DShot setup. Also
allows for neopixel without other DMA controlled output types for LEDs
in AP_Periph
allow mask updates to be disabled
send dshot commands even if armed - they will be accepted as long as throttle is at zero
only accept low-priority dshot commands while disarmed
apply reversed and reversible mask as servo channels
add support for dshot beepcodes through tonealarm
add support for dshot reversal and command queue
add support for dshot commands to all channels
correctly manage channel enablement in PWM groups
Correctly send dshot commands when using bi-dir dshot
allow reversible settings to be changed
ChibiOS: allow more than one type of ESC for dshot commands
Only execute reverse/reversible commands on BLHeli
add support for checking active ESCS
mark ESCs active when bdshot telemetry is returned
allow dshot alarm to be disabled
allow priroitized dshot commands
allow faster rates synchronized to the loop rate
synchronize 1Khz and use Betaflight definition for prescaler
adjust dshot bitrates
don't allocate IC DMA if already allocated
cancel DMA pulses correctly
try really hard to align pulses with push() by making each dshot pulse event driven
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
protect serial LED buffer transfers with mutex
protect serial LED buffer size with mutex
prevent serial LED interactions before rcout is ready
allocate a serial led buffer per channel that needs it
setup clock mask when needed
add support for sampling GPIO pins using timer
don't restart pwm group when not doing bi-dir
fix hwdef generation preproc for TIM DMA
decode telemetry at the start of the dshot cycle
calculate dshot pulse separation correctly and ensure we output rapidly enough
calculate dshot min periods and timeouts correctly
refactor dshot_send() into dshot_send_groups()
use bi-dir dshot channel mask
selectively enable bi-dir RC Channels
process bi-dir mask correctly when allocating DMA channels
allow UP and CH DMA channel sharing
optionally enable bidir vars in hwdef.

this fixes a problem where the user requests DShot (which rquired DMA)
on an output channel which cannot allocate a DMA channel. We end up
sending normal PWM, so the string representation of the output modes
should reflect that
