c93ccf5a4c lpc: use levinson for the first pass of multipass cholesky 
Levinson is faster, and cholesky is only needed if we want to apply different
weights to different samples, which doesn't happen on the first pass.

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.)
