Prefer "non-negative" over "positive", the former is more accurate.

This should simplify inclusion in monolithic tool manuals.

Note: a lot of muxers already do the flushing explicitly.

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.

Also try to document the rational behind it.

"analyzeduration" is not used to detect the input duration, but to
specify the max probe data duration. Fix option description and related
doc entry accordingly.

The metadata muxer/demuxer belongs to the formats documentation.

In particular, make "See Also" chapter rendered in HTML output.

Factorize.
