Using mixers on the IO side had a remote benefit of being able to
override all control surfaces with a radio remote on a fixed wing.
This ended up not being used that much and since the original design
10 years ago (2011) we have been able to convince ourselves that the
overall system stability is at a level where this marginal benefit,
which is not present on multicopters, is not worth the hazzle.

- store parameter type and if volatile separately (saves kilobytes of flash)
- use Bitset for tracking active and changed parameters
- use atomic for autosave_enabled flag
- compile at ${MAX_CUSTOM_OPT_LEVEL} (-O2 on non flash constrained boards)
- currently the main change is that it reduces the max number of ORB multi instances to 4, but usage will be expanded as needed
- limits number of EKF2 multi instances to 2.
- enabled on all cortex m4 boards
- skip avionics rail voltage check when USB connected
- skip forced reboot on USB disconnect if circuit breaker set
- avionics voltage preflight check don't silently fail if system_power unavailble
- explicitly set supply check circuit breaker (CBRK_SUPPLY_CHK)
- 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)
This moves the handling of the BAT%d_SOURCE param inside of the battery
library. Users of the library now pass the source instead of the flag
whether to publish. The battery library then checks if the source is
selected using the param and publishes accordingly.
Since we removed the strange system_source flag, we now need to look at
all batteries in commander.
For current estimation - I think - it makes sense to sum them up.
