frame sample count calculation was incorrect

The duration of the first packet was being calculated incorrectly, leading to
an incorrect timestamp offset.

It is not necessary to store the bit stream length in a RV34DecContext
field.

This is a hopefully temporary solution until lavfi can properly deal
with resolution changes.

This option only applies to streamcopy, but is currently processed only
when encoding.

If the creation time is stored in the file as a zero, the
mov demuxer skips exporting the creation time. Currently,
files muxed without a creation time get demuxed with a
Jan 1st 1970 creation timestamp.

Remove some unneeded memsets.

Instead of busy waiting use poll();

Let pass the codec name to -pixel_format and introduce -input_format.

al15_44 uses independent coupling.
al18_44 uses PNS (perceptual noise substitution).

Fixes al_sbr_cm_48_5.1.mp4.

The functions are not used in any part of Libav, therefore testing them in the
cabac-test is unnecessary. Since this makes them unused, remove the functions.
