With all the VLAs gone, make sure they never come back.

This gets rid of the variable-length scratch buffer by filtering 16
pixels at a time and writing directly to the destination.  The extra
loads this requires to load the source values are compensated by not
doing a round-trip to memory before shifting.

Instead of using an evil VLA, fall back to C version when edge
emulation is needed.  MPEG4 GMC is a rarely used fringe feature
so the speed loss is an acceptable cost for safer code.

Discontinuous transmission is an addition to VAD/VBR operation, that
allows to greatly reduce bitrate for silent chunks or stationary
