Fixes bug #630442.

This is especially needed when switching between a non-sparse and sparse
video stream, see bug #537382. It also lowers the time needed for switching
between streams a bit.

Fixes bug #638897.

This allows the state change from PAUSED to READY to be faster.

Fixes bug #628337.

Fixes #649969

Same as core (make implicit requirement explicit).

bytes_written is a gsize which is unsigned and thus never < 0.

th_encode_ctl() returns an int. Using a gsize result in bogus <0 checks.

We don't want to return without setting taglist=NULL if asserts are on and with
setting taglist=NULL otherwise.

Previously we checked mute_csource to determine wheter we need to premultiply
volumes and mute values. That fails as we unrefs mute_csource and set it to
NULL after. Use an extra flag instead.

Move the warning on unsupported units to the swicth-case. Move fetching the
pending tags down to where we use them.

Otherwise we never write the tag. This would also be consistent with the code in
deserialize_scene_type().

We check for matching_attr!=NULL right before already.

Add more symbols (from unused.txt). Move the whole bunch of riff-fourcc defines
to std section too (no one is hoing to document them, right).

If someone intents to document them and the fields we can move them back.

Use a trick to avoid documenting all 100 enums.

Because the spec for the ringbuffer can change when changing
the caps, we must recalibrate the clock.
