For some strange reason "-t" option was only implemented
for input files while both "-t" and "-to" were available
for use for output files. This made extracting a range from
input file inconvenient.

This patch enables -to option for input so one can do

    ffmpeg -ss 1:23:20 -to 1:27:22.3 -i myinput.mkv ...

The -map option allows for a trailing ? so that an error is not thrown if
the input stream does not exist.
This capability is extended to the map_channel option.
This allows a ffmpeg command not to break if an input channel does not
exist, which can be of use (for instance, scripts processing audio
channels with sources having unset number of audio channels).

This only supports one device globally, but more can be used by
passing them with input streams in hw_frames_ctx or by deriving new
devices inside a filter graph with hwmap.

(cherry picked from commit e669db7610)

(cherry picked from commit 303fadf596)

add a per-stream option for setting the encoder timebase.
the following values are allowed:
0 - for video, use 1/frame_rate, for audio use 1/sample_rate (this is
  the default)
-1 - match the input timebase (when possible)
>0 - set the timebase to provided number

The examples used to drop frames in most cases which
was probably not what users expected.

Fix double UTF-8 encoding on output files.
makeinfo / texi2any does not seem to provide a way of setting
it globally for toplevel files.

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.
