avformat: AviSynth demuxer rewrite

Directly loads AviSynth through LoadLibrary instead of relying on
Video for Windows, and supports using AvxSynth (via dlopen) to
open scripts on Linux and OS X.

Error messages from AviSynth/AvxSynth are now reported through
av_log and exit, rather than the traditional behavior of generating
an error video that the user would need to watch to diagnose.

The main rewrite was authored by d s <avxsynth.testing@gmail.com>
from the AvxSynth team, with additional contributions by

vp9: implement top/left half (4x4) sub-8x8-IDCT.

For that specific case (eob>3&&eob<=12), runtime of idct8x8 goes from
668 to 477 cycles. For all idct8x8, runtime goes from 521 to 490 cycles.

vp9: split pre-load of 11585x2 out of 1d idct macro.

This allows us to load it only once, instead of twice, in this function.

vp9: minor refactorings in idct ssse3 assembly.

Make register usage in macros explicit; change mulsub_2w_4x to use 2
instead of 3 temp registers.

vp9: split x86 assembly in two files.

doc: add script to compute texi files dependencies

Replace the inline awk script with a Perl script which tracks the

This allows to correctly track dependencies for files including files
with a second level include (for example: ffmpeg-devices.texi ->
devices.texi -> outdevs.texi).

This also adds a dependency on perl for computing the dependencies, which
should not be a problem since perl is already required all the way for
building documentation.

This is a variant of commit 628ceac6526724d35cb390cc1f88344f4ea22eb4

webp: add a special case for a huffman table with only 1 symbol

The vlc reader cannot handle 0-bit huffman codes. For most
situations WebP uses the "simple" huffman coding for this case,
but that will only handle symbols up to 255. For the LZ77 distance
codes, larger symbol values are needed, so it can happen in rare
cases that a normal huffman table is used that only has a single
symbol.

webp: do not call av_frame_free() on the user-provided frame

Fixes double-free on error.
