f40cf96ec0 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.

9db706206d doc: Consistently use 'filtergraph'
We used to use 'filtergraph' or 'filter graph' randomly.

'filtergraph' was chosen due to having 57 occurrences in
the documentation, whereas 'filter graph' had only 19.

18f43de964 doc/ffmpeg,ffmpeg-formats: avoid to mention ffmpeg options from formats.texi
Also extends documentation for timestamp related ffmpeg options, in order
to make more apparent the fact that muxer processing may change the

cb2bd91413 ffmpeg: add the -canvas_size option.
Allows, amongst other things, to override the size guessed
by the sub2video hack.

Note: the -s option could have more or less the same semantic,
but it receives a special treatment by the options system.

f185a040b0 doc/ffplay,ffmpeg: mention the corresponding negated option for -stats
This helps lazy users who didn't read the part about boolean options, in
case they grep for "-nostats".

-stdin and -stats are the only booleans option enabled by default. This
is a partial fix for Trac ticket #2332, a complete overhaul of boolean
options documentation is probably overkill.

b448677e6e doc: remove inclusion of libav* documentation in tools
This shrinks the tool manuals to a manageable size. Relevant manuals are
referenced in the "See Also" chapter.

Overall documentation inclusion should still be possible through the use
of a conditional variable set during configuration time, if someone feels
the need for a huge-wall-of-text-fashioned manual.
