- always check with state machine before reboot/shutdown
- respect BOARD_HAS_POWER_CONTROL (shutdown from command, low battery, power button)
- px4_shutdown_request add optional delay and always execute from HPWORK
- px4_shutdown_request split out px4_reboot_request
- increase stack sizes to run cleanly under stackcheck
- this is likely overkill for most boards, but using stackcheck to set our minimum ensures we have a very safe margin on regular builds and it's something we can currently afford
- remove holybro_durandal-v1_stackcheck from test rack (there's only one unit)
Change PID to 0x4b:
Holybro obtained their own PID and VID but APM did not follow
the PX4 convention of makeing the board_id (0x8b) match the PID)
Incorporated the Upstream Bootloader state sequencing checking change.
Change the usb cout to send all chars in 1 write.
