Martin Storsjö 75644335b9 lavc: Move start code finding to utils.c 
This allows dropping the mpegvideo dependency from a number of
components.

This also fixes standalone building of the h264 parser, which
was broken in 64e438697.

Hendrik Leppkes c3ebfcd6e1 mpegvideo: allocate hwaccel privdata after the frame buffer 
This ensures the hwaccel privdata does not leak when a frame buffer could
not be allocated (and toggle the assert when the frame is re-used).
Having no frame buffer available is quite common when using the DXVA2
hwaccel in situations where the DXVA2 renderer is being re-allocated, for
example when moving between displays.

Conflicts:

The luma init is left at 0x80 as it was previously, and tested and
working since a long time. Its also mandated to be 0x80 by at least
one specification. Cases that need different values already had
code in place to handle them.

Anton Khirnov 293065bdb5 mpegvideo: initialize dummy reference frames. 
Do not rely on get_buffer initializing them.

Changes yadif tests (off by one in one border pixel), because yadif
reads from those uninitialized lines.

It does not help as an abstraction and adds dsputil dependencies.
