ffmpeg looks for both .ffpreset and .avpreset files depending on whether the
-[avsf]pre or -pre option is used. Added two sections for each type of preset
including the rules according to which files are searched.
(Notably, the lookup order is swapped for avpreset files, because it first
looks for <codec>_<arg>.avpreset and then for <arg>.avpreset.)
This removes the section explaining -pre only, which was under "Examples",
where it did not really make sense.

Replace "frames to record" with "frames to output". The "to record"
makes it seem like an input option, or that it would capture the frames
instead of outputting them.

The first sentence of each of the modified man pages are worded a bit
awkwardly. These minor copy-edits should make them clearer.

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.
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.

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