[RFC,0/3] Split up v4l2-mem2mem.c into a core and codec part

This RFC series splits up v4l2-mem2mem.c into a core and codec part.

This is a first stab at this, I'm not entirely happy with the
fact that v4l2_m2m_qbuf has to call to _v4l2_codec_qbuf helper
for some codec specific handling.

In any case, splitting this up makes it easier to maintain (IMHO)
and probably makes it easier as well to improve the codec part.

Regards,

	Hans
