   Bring UART4 bufffer sizes in alignment with FMUv2 Telem1

I sometimes start jmavsim independently from px4, and in that case jmavsim
should not be killed. These are the commands:
./Tools/jmavsim_run.sh
make posix none

This allows a simple-to-use bootloader update mechanism to switch from
fmu-v2 to fmu-v3 target that has more flash.

- this ensures that the MAV_TYPE parameter is always updated
- previously it could happen that the simulator module was using a wrong
MAV_TYPE value because it only read the parameter value at initialisation

   The update check is on ORB_ID(safety) but the copy
   was from ORB_ID(actuator_armed).

   Accept PWM_SERVO_[ENTER|EXIT]_TEST_MODE as a noop.
   As long as the mixer in passthrough and armed the
   pwm test will work.

   A hardfault was happening on:
    fmu stop
    fmu mode_pwm
    pwm info

   The _mixer was null and being dereferenced to access the trim
   setting that were moved to the mixer from the fmu.

   This commit fixes that but making the getter issue a warning
   and the setter fail.

  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.

This adds text to markdown output to explain how params are generated

MPU6050: fix implicit float to double conversion
