mpegvideo: increase edge_emu_buffer size for VC1

The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma
and needs more space. That was not a problem before f1d8763a02b5fce
since the size for edge_emu_buffer was always calculated with 2 byte per
pixel since the linesize was not known.

Fixes occasionally fate errors in vc1_sa10143.
doc/texi2pod: rework man inclusion logic

Ignore @c man begin ... @c man end comments, rely on @chapter for marking
the beginning of the various manual top level sections.

This allows us to write markup which is not dependent on the specific
texi2pod.pl implementation.

This change causes a few rendering issues, which will be fixed in further
patches.
doc: use a common authors.texi file blurb

Factorize.
doc: rework synopsis section for ff* tools

Fix syntax, remove pointless introductory sentence, improve overall
consistency.
doc: extend "See Also" chapter rendering for ff* tools

Add more references, and generate alternative variants for HTML and POD
output. In particular, this allows to render a "See Also" chapter in the
HTML output.
doc: extend "See Also" chapters in component manuals

In particular, make "See Also" chapter rendered in HTML output.
doc: extend "See Also" chapters in library manuals

In particular, make "See Also" chapter rendered in HTML output.
Show underscores in av_get_codec_tag_string().
lavfi/setpts: enable debug logs, and improve/extend debug messages
doc: remove mention of fifo filter in the introduction.

It's confusing and not necessary, especially in the introduction.

mov: handle h263 and flv1 for codec_tag 'H','2','6','3'

The sample in https://bugzilla.libav.org/show_bug.cgi?id=393 and
samples/F4V/H263_NM_f.mp4 both have codec_tag H263 for different
codecs. H263 is apparently used by Flash Media Server for Sorensen
Spark videos.

Patch based on commit 5442083b1c541dd166b3adf39131259fc846a62b by
Carl Eugen Hoyos. Fixes bug 393.
