There is no longer a separated FBW in normal operation for fixedwing,
only a single AP task/thread.
The code for main_ap is now factorized for all firmwares.
Dual MCU support (separated AP and FBW) is still possible, based on the
rotorcraft implementation and intermcu pprzlink messages. Relevant code
is also factorized and available in all firmwares.
The recovery mode (in case of hard fault) is still available for
fixedwing with ChibiOS implementation.
Only intermcu_uart is supported at the moment. Other options (spi/can)
might be added back in the future if really used.
Some other evolution are made:
- in the radio_control and actuators modules, now integrated to AP and
using ABI messages
- the message parsing on datalink event (defined in module) that is now
properly filtering the messages based on their class and allowing to
have multiple callbacks for the same message
- cleaning the part of code that were using the old intermcu fixedwing
interface
- support depends, conflicts and provides nodes, all under a 'dep' node
- autoload are kept for now and are not moved yet
- modules are updated for new dep format
- it is now required that module's name and filename are the same
When using a different datalink buffer than dl_buffer, the callback
functions from the modules must use the buffer address passed as a
parameter, otherwise there is no guarentee that the correct buffer will
be parsed.
