The code was forcing the CV reload, but not resettting the count
  this would cause short and long blinks during breathing.

  this change allows the CV to update at 50Hz (20 ms) asynchronously.
  So the LED update rate of 40Hz (25) will take effect on the next
  FTM counter change, end of the prescaler counting, after CnV register
  was written.update.

  This will disable the fxos8701cq internal mag on
  the NXPHlite. There are random noise spikes on the
  HIGHRES_IMU.[x|y|x]mag. Even with all other SPI
  devices shut down, the noise is still present.

It seems that the oneline to find the process ID of any running jMAVSim
instance was not working correctly.
1. On Linux, the name of the process does not contain Simulator but
   jmavsim_run.jar. Also, it triggers incorrectly, if you have opened
   Simulator.java using the command line :).
2. The cutting to get the PID at the end does not work as intenteded and
   gives the username instead of PID, at least on Arch Linux. Using awk
   should fix this.

    c85f446 2018-09-06 Daniel Agar - mpu6050 fix abs double promotion

Edit the init.d-posix files to set MAV_TYPE script variables, and alphabetize lists in a few places.

Set parameters directly rather than script variables in VTOL airframe config files and alphabetize lists.

Starting with cmake version 3.12 the cmake -E copy_directory
command fails if the source directory does not exist. This results
in a build failure. This fix creates the source directory before
the copy which does not harm if the source directory exists.

Closes: #10368

Not needed anymore, use PX4_ESTIMATOR.

 - this allows interacting with the submodules check

 - remove radio_status type since there's no type support in mavlink
