This allows to set the environment variable NO_PXH to start SITL without
the interactive pxh> shell. For this, px4 is called with the -d arg
which sets it to deamon mode.

This feature is handy to script sitl_run.sh.

Most people will use a quad, not FW.

This disables the following modules to save flash:
- mpu9250 driver because the MPU9250 is rarely used on Pixhawks
- Snapdragon RC PWM passthrough which is rarely used and definitely a
  special/custom configuration. Also, it will soon be obsolete with the
  upcoming PWM support on Snapdragon.

The generated binary hash was off by one.

Pushed by accident.
This reverts commit 87f0ec19.

I could not figure out how to make sense out of the binary git data.
Therefore, I replaced the px4_git_version_binary with the first 8 bytes
of px4_git_version (char[]) and this is easily readable when it arrives
on the other side.

- we interface over the base class pointer so we don't need any pointers
to the derived classes of VtolType

If the Python versions are specified, this breaks the build on Ubuntu systems
where Python3 is also installed but the extensions such as python-empy
are not installed. One could, of course, install python3-empy to fix
this but that's not in the instructions or error messages and therefore
not straightforward.

It is therefore probably better to just use the system default which
ends up being 2.7 on Ubuntu.

Disable resetting alt/pos setpoint flags if switching to position control from auto when very close to takeoff setpoint

Always check reset flags in auto. Only set reset flags to true when required. Do not limit hor/vert setpoint acceleration when setpoints are reset.

This brings support for Distros that use Python3 by default such as
Arch Linux.

- do not try to shift the target waypoints when a reset occurs in position
control mode. Just make it lock into the current heading.
