options: rename -lavdopts to -vd-lavc, -lavfdopts to -demuxer-lavf
Also change manpage so that top-level options are documented instead of suboptions. Suboptions still work, but might go away eventually.

---lavdopts=<option1:option2:...>
- Specify libavcodec decoding parameters. Separate multiple options with a
- colon.
-
- *EXAMPLE*: ``--lavdopts=gray:skiploopfilter=all:skipframe=nonref``
-
- Available options are:
-
- bitexact
- Only use bit-exact algorithms in all decoding steps (for codec
- testing).
-
- fast (MPEG-2, MPEG-4, and H.264 only)
- Enable optimizations which do not comply to the specification and
- might potentially cause problems, like simpler dequantization, simpler
- motion compensation, assuming use of the default quantization matrix,
- assuming YUV 4:2:0 and skipping a few checks to detect damaged
- bitstreams.
-
- o=<key>=<value>[,<key>=<value>[,...]]
- Pass AVOptions to libavcodec decoder. Note, a patch to make the o=
- unneeded and pass all unknown options through the AVOption system is
- welcome. A full list of AVOptions can be found in the FFmpeg manual.
-
- Some options which used to be direct options can be set with this
- mechanism, like ``bug``, ``gray``, ``idct``, ``ec``, ``vismv``,
- ``skip_top`` (was ``st``), ``skip_bottom`` (was ``sb``), ``debug``.
-
- *EXAMPLE*: ``o=debug=pict``
-
- skiploopfilter=<skipvalue> (H.264 only)
- Skips the loop filter (AKA deblocking) during H.264 decoding. Since
- the filtered frame is supposed to be used as reference for decoding
- dependent frames this has a worse effect on quality than not doing
- deblocking on e.g. MPEG-2 video. But at least for high bitrate HDTV
- this provides a big speedup with no visible quality loss.
-
- <skipvalue> can be one of the following:
-
- :none: Never skip.
- :default: Skip useless processing steps (e.g. 0 size packets in AVI).
- :nonref: Skip frames that are not referenced (i.e. not used for
- decoding other frames, the error cannot "build up").
- :bidir: Skip B-Frames.
- :nonkey: Skip all frames except keyframes.
- :all: Skip all frames.
-
- skipidct=<skipvalue> (MPEG-1/2 only)
- Skips the IDCT step. This degrades quality a lot of in almost all
- cases (see skiploopfilter for available skip values).
-
- skipframe=<skipvalue>
- Skips decoding of frames completely. Big speedup, but jerky motion and
- sometimes bad artifacts (see skiploopfilter for available skip
- values).
-
- threads=<0-16>
- Number of threads to use for decoding. Whether threading is actually
- supported depends on codec. 0 means autodetect number of cores on the
- machine and use that, up to the maximum of 16. (default: 0)
-
-
---lavfdopts=<option1:option2:...>
- Specify parameters for libavformat demuxers (``--demuxer=lavf``). Separate
- multiple options with a colon.
-
- Available suboptions are:
