PyZBufferTo3D struct).
[profiler] do not record time if not profiling

Add support for service abortion with the socket interface

While here, improve logging msg when requesting an explicit abortion
[sockets] Fix processing of concomittent socket requests

Because we were using 'readline' only once on sockets ready to
be read, we could miss requests when several came in a row.

The Python 'readline' API is however blocking.

Rewritten this part to use low-level 'recv' and manually
splitting the buffer into independant requests.

This assume the whole requests arrive as a single TCP package.
waypoint actuator: improve behaviour when cancelling goto

It does not try to reach anyway the original target
[cmake] Integrate doc generation part to cmake
