AP_HAL: added missing CONFIG_HAL_BOARD_SUBTYPE #define for HAL_BOARD_VRBRAIN
Copter: sanity check throttle deadzone
InertialSensor: reorder .cpp file to match .h

No functional changes
INS: add get_accel_health_all and get_gyro_health_all

Returns true only if all available accels or gyros are healthy
Copter: check all gyros and accels in pre-arm check
Copter: individual accel and gyro status to GCS
Copter: pre-arm consistency check of accels
Copter: add short delay to arming to allow RC input

The short delay gives time for the RC inputs to be processed which
removes the chance of a false-positive on the "late frame" radio check.
A false positive could lead to an immediate disarm right after arming.
Copter: land check gets overall throttle and rotation rate check

add check that overall throttle level is below the non-takeoff throttle
instead of just checking that it's motors have hit their lower limits
because low limits can also be caused by high yaw rotation requests.
Absolute climb rate requirement reduced to 30cm/s
Copter: pre-arm consistency check of gyros
Cotper: AC3.2-rc7 release notes
Copter: version to AC3.2-rc7
Merge remote-tracking branch 'upstream/ArduCopter-3.2' into chm
Bug fix to roll pitch target angles
