More grep-friendly and more consistent with the rest of the FFmpeg
API.

The new name is shorter and more consistent with the FFmpeg API, and
sounds less evil.

Rename the variable filter to filt_ctx in link_filter_inouts, as the variable denotes a filter context.

This new version:
1.  Works on 24-bit and 32-bit input, not just 32-bit.
2.  Doesn't try to run on 16-bit or 8-bit, instead of outright crashing.
3.  Does proper alpha-blending, so cursor shadows look correct.
4.  Doesn't swap R and B.

Mostly fixes issue 1997.
Fixes issue 2056.

Muxlength does not include the 3 bytes of AudioSyncStream() before the
AudioMuxElement(). If these three bytes are not accounted for the last three
bytes of the LATM packet are sent back to the decoder again.

Fixes issue244/mux2.share.ts

This fixes a regression since svn rev 24752, where the real_setup pointer
was set incorrectly. The arithmetic with the real_setup_cache pointer
is in units of enum AVDiscard, so the sizeof multiplication should be removed.

Contrary to progressive, just being able to crop up to 14/15 pixels
is not enough to encode all supported resolutions, and the new
behaviour is also consistent with e.g. MPEG-2 etc.
