It removes useless hacks in the code.

This reverts commit 47cf242f.

This reverts commit 8cf35578.

It now supports all combinaisons of
Destinations:
 - YV9, YV12, I410, I411 (8 bits)
 - I420, I422, I444 (8, 9 and 10 bits, native endianness only)
 - YUYV and the various variants
 - NV12/NV21
 - RV15, RV16, RV24, RV32
Sources
 - YUVA
 - RGBA
 - YUVP

The quality of the blending is the same, and the speeds for I420 is the same
(not tested others combinaisons).

Support for blending I420 over another picture has been removed (I don't
see the use case and it simplify the code).

It closes ##5477.

U/V planes were swapped twice.

Fixes #5207

The deadlock would occur when the VLM would stop an instance and detach
its RTP output, at the same time as an RTSP client would issue a VoD
command to the VLM.

Unfortunately this introduces a race condition where wrong RTP-Info can
be returned.
