RealPlayer does not play rv20 files when sizes are not multiple of 4

Introduced in d7d6efe42b.

Since a NAL_DPA can start a new frame it has to be handled before
ff_thread_finish_setup is called.

This requires to move the avcodec_default_free_buffers() call to
ff_MPV_common_end() since otherwise delayed pictures would get freed
during a size change.

Direct rendering capable decoders call get_buffer() which will set the
frame parameters.

Prevents frames with wrong parameters when a decoder outputs delayed
frames after a resolution or pixel format change.

Fixes a crash in the fuzzed sample sample_varPAR.avi_s26638 with
alternating bit depths.

Interlacing is not supported at all and mismanaged down the normal
codepaths causing possible buffer management issues.

Use this in VP8/H264-8bit loopfilter functions so they can be used if
there is no aligned stack (e.g. MSVC 32bit or ICC 10.x).

This decoder is quite simple and none of the MpegEncContext complexity
is actually needed.
