92436e8ad9 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.

b2045c44a9 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.

f9a0d4c6e0 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.

8729964b99 vp9: split x86 assembly in two files. 
(And in future, loopfilter or intra pred could be put in their own
respective files also.)

d085f80fa1 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.

56572787ae Add Windows resource file support for shared libraries 
Originally written by James Almer <jamrial@gmail.com>

With the following contributions by Timothy Gu <timothygu99@gmail.com>

* Use descriptions of libraries from the pkg-config file generation function
* Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
  file is distributed" [1].
* Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
* Only build the .rc files when --enable-small is not enabled.

24abd806ea ljpegenc: deMpegEncContextize 
The encoder uses almost none of the mpegvideo infrastructure, only some
fields from MpegEncContext.

The FATE results change because now an all-zero quant matrix is written
into the file. Since it is not used for anything for ljpeg, this should
not be a problem.

66499f34b5 mpegvideo: do not set current_picture_ptr in decoders 
This code was originally added in
5f1948111a to h263 to set decoded frame
pts to some random numbers (removed in
a1c5cc429d) and then cargo culted to other
decoders.

The code is left in h263dec for now, since some part of the decoder
(apparently OBMC) relies on the specific previous frame to be reused.

Original decoder seems to always use 176x128 tiles anyway and this helps
avoiding lots of issues with odd tile sizes in fuzzed files.

The check for (prim_channels > 2) before calling dca_downmix made these

Having dual mono, Lt/Rt and sum-difference layouts print errors when
regular Stereo doesn't seems pointless.
