Title: Explicit failsafe

This PR is a rework of #966 .

This change evaluates the rc status flags recently added to PX4Firmware to make the RC input handling more robust. RC channel values are double-buffered now and forwarded only if there is no condition that could lead to compromised channel values.

Additonally, any RC input with channel_count < 5 is rejected, as such signals are obviously of no value for us.
