* [autopilot] refactor autopilot API for both firmwares
With this, fixedwing and rotorcraft are mostly using the same interface
for the autopilot. Some specific code and messages handling are still
firmware dependent.
A large part of the autopilot logic of the fixedwing is moved from
main_ap to autopilot_static.
More getter/setter functions are provided.
* [autopilot] update the rest of the system and the conf
for using the refactored autopilot API
* [autopilot] fix some errors from CI servers
* [actuators] use dummy actuators module to prevent autoloading
* Rename Bart_heliDD_INDI.xml to tudelft_bs_helidd_indi.xml
* Rename Bart_heliDD_pid.xml to tudelft_bs_helidd_pid.xml
* Delete tudelft_course2016_bebop_colorfilter.xml
* Delete tudelft_course2016_bebop_avoider.xml
* [actuators] don't autoload actuators when set to 'none'
* [gcs] autodetect firmware for strip mode button
