timeline support is disabled.

x86: ac3dsp: Remove 3dnow version of ff_ac3_extract_exponents

The function requires increasing the fuzz factor for the ac3/eac3 encode
tests and even so makes fate fail. It only provides a slight encoding
speedup for legacy CPUs that do not support SS2. Thus its benefit is not
worth the trouble it creates and fixing it would be a waste of time.

doc/filters: put vidstab filters documentation in a sensible order

It was removed in 62447248f3e5eb95dbd9f123696321903d4d0921.

doc: remove all-components.texi, include its content verbatim

Force re-generation of the manuals when an included file is modified.
The current dependency generation system is enable to track nested
inclusions.

The drawback is that the files will be generated even when there is no
strict need (for example if filters.texi is modified, ffmpeg.1 is
rebuilt), thus it trades a false negative with a false positive.

lavf: introduce AVFMT_TS_NEGATIVE

Most formats do not support negative timestamps, shift them to avoid
unexpected behaviour and a number of bad crashes.
