move to single OSD font on some boards
this saves about 12k on these boards. They were also extremely close
to overflowing flash, under 2k on some
Now that we support having an OSD font on the microSD card (where
available) we can reduce built in fonts without a large functionality
impact
This also disables some less used features on these boards:
- generator support
- object avoidance path planning
- precision landing
This will give us some breathing room on these boards
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 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
