- no longer start sercon or mavlink usb by default
- on USB connection (VBUS) monitor serial USB at low rate and start Mavlink if there's a HEARTBEAT or nshterm on 3 consecutive carriage returns
- the mavlink USB instance is automatically stopped and serdis executed if USB is disconnected
- skipping Mavlink USB (and sercon) saves a considerable amount of memory on older boards
Using mixers on the IO side had a remote benefit of being able to
override all control surfaces with a radio remote on a fixed wing.
This ended up not being used that much and since the original design
10 years ago (2011) we have been able to convince ourselves that the
overall system stability is at a level where this marginal benefit,
which is not present on multicopters, is not worth the hazzle.

These changes remove the two code paths to updates (forceupdate and update) and try to reboot and bootload IO independent of its state, wether it is in bootloader mode already, safety switch is off or if it is in "nominal state" (running and safety on). This ensures that there are no conditions where user error or boot sequence can prevent a successful upgrade. The only state where an upgrade will not be done is if the system is fully armed.
- drivers/tone_alarm: move to ModuleBase and purge CDev (/dev/tone_alarm0)
- drivers/tone_alarm: only run on tune_control publication (or scheduled note) rather than continuously
- drivers/tone_alarm: use HRT to schedule tone stop (prevents potential disruption)
- msg/tune_control: add tune_id numbering
- systemcmds/tune_control: add "error" special case tune_id
- move all tune_control publication to new uORB::PublicationQueued<>
- start tone_alarm immediately after board defaults are loaded to fix potential startup issues
- for SITL (or other boards with no TONE output) print common messages (startup, error, etc)
* Lists ROMFS files explicity instead of using GLOB_RECURSE
Previously, when ROMFS files that were not airframes were touched, the ROMFS
would not be rebuilt. The ROMFS files are now specified explicityl in a
CMakeLists.txt file that is located in the root ROMFS directory.
Now when one of the ROMFS files is touched the whole ROMFS is rebuilt.
When new files are added to the ROMFS, they need to be explicity added to
the CMakeLists in the ROMFS root directory.
* ROMFS: adds individual CMakeLists files in each subdirectory
Also moves the temporary ROMFS build directory to ${PX4_BINARY_DIR}/ROMFS/genromfs
so that the cmake_install.cmake files and the CMakeFiles directories (generated whenever
are not add_subdirectory() is called) are not generated in the temporary ROMFS directory
from which the ROMFS binary is created.
* cmake ROMFS generate add px4_add_romfs_files function
* ROMFS CMakeLists: adds explanatory comment to px4_add_romfs_files function
* ROMFS CMakeLists: updates copyright headers
