Also extends documentation for timestamp related ffmpeg options, in order
to make more apparent the fact that muxer processing may change the
timestamps values.

Hopefully increase readability.

List of clobbered registers fixed and added where it is lacking.

This race will always happen sooner or later in a multi-threaded
environment and it will over time lead to OOM.
This fix works by spinning, there are other ways by which this
can be fixed, like simply detecting the issue after it happened
and freeing the over-allocated memory or simply using a mutex.

Those are not usable from the avtools, so mentioning them in the
manpages just confuses the reader.

The total frame size is a combination of the 12 bits in the sequence
header and 2 more bits in the the sequence extension. While the
specification explicitly forbids the dimensions from the sequence header
from being 0 (thus ruling out multiples of 4096), such videos
apparrently exist in the wild so we should attempt to decode them.
