Squashed commits:
[290660d] voted_sensors_update: revert the new_accel_data check (and others)
The check removed the ability to detect sensor timeouts.
[c8dc7ad] sensors: publish changes to sensor selection
[dd90dec] sensors: ensure all sensor selections published first time
Move into functions.
Reset probation time and recalculate checks if a mode change is demanded to give the operator ability to regain control as soon as possible after nav performance is regained. (+11 squashed commits)

[a4bb800] commander: enable pilot to quickly recover from loss of position accuracy
[19e16a0] commander: rework postal probation time
[f96284e] commander: rework bad pos and vel test probation time
[00d5f0c] commander: Allow EKF preflight checks to pass with moving vehicle
Separates the 'is using GPS' and the GPS quality checks.
Uses a reasonable subset of the GPS quality checks which allows checks to pass if the vehicle is moving.
[4cdfb5c] commander: remove unused variable
[349385a] commander: add EKF GPS quality checks to pre-arm checking
Only perform check if GPs checking is activated by parameter setting.
Display fault messages that makes it clear if EKF quality checks are failing or the EKF is not using GPS for another reason. We do not want to confuse this with GPS lock.
[340ae29] commander: make position invalid fail-safe more sticky
Require check to pass for 7 seconds before exiting failsafe. This is required because if GPs is failing innovation tests for a prolonged period, the EKF will periodically reset to the GPS and report good accuracy at the time of reset.
Adding this delay gives time for an underlying error condition (eg bad IMU or compass) to be re-detected.
[b04ac95] commander: Increase RAM allocation to eliminate low stack warnings
[9dca12f] commander: add missing position invalid fail-safe responses
[69f264d] commander: Update position invalid fail-safe responses
Replace separate logic for each case with a generic function
Add velocity checks.
[8e8cef1] commander: rework position validity checks
Consolidate existing checks for global and local position validity and add checking of velocity accuracy.
Enable checks to be bypassed using the CBRK_VELPOSERR parameter.
When the CCER is cleared the IO pin tends to float. The FMUV4
HW has no TXS0108 and if cut off while high will decay.
By adding the pull down the pins will seek the low state faster.
13.8 us from off to decabe below threshold.
The ramtron driver already calls SPI_LOCK when accessing the
FRAM.
Removed the interrupt lockout and anabled the SPI_LOCK
in the ms5611 driver on any HW where the
PX4_SPI_BUS_BARO == PX4_SPI_BUS_RAMTRON
