985f34b756 utils: fix avcodec_flush_buffers pre-reference counting compatibility 
The to_free AVframe must be freed just like the other ones.
Indeed, the calling application may expect all frames to be
released.

(This regression caused use-after-free in VLC with hwaccel.)

31980b6abd vmd: decode videos with no LZ buffer size provided - they might not need it 
The buffer is used for an additional pass of frame compression, so videos
can be coded without ever using it (and some are coded so indeed, e.g. in
Woodruff and the Schnibble of Azimuth game).

33f64fd5d5 indeo4: expand allowed quantiser range 
Indeo 4 has quantiser range 0-31 instead of 0-23 for Indeo 5, and clipping
quantiser leads to incorrect quantisation and DC prediction on low-quality
videos.

This fixes bug 259.

bf20cdbd86 mpeg12: skip frames consistently 
The decoder did not start predicted frames with missing references but
called the end of frame handling on them anyway. This caused an
assertion in the VA API HW accelorator since it tried to render a
picture with uninitialized buffers.
