This set of patches is what I am submitting as qualification for the google
summer of code.
I wrote sse2/avx2 versions of several of the postprocessing filters
(namely the accurate deblock filter and all the deinterlace filters), and made
several

Also pulled QP initialization out of inner loop, which removed some redundent
code.
Added some dummy fields to PPContext to allow current code to work while
changing the rest of the postprocessing code to support the arrays.

I did my best to make as few changes as possible to the formatting when
adding new code, so this commit is just a means of making the format
changes that go along with the new code.
Mostly these are just changes in indentation, but I also re-formatted a
few assignment statments (from x= y - x =
This patch contains the code for the avx2/sse2 versions of the new
function, but they are deliberately ignored, since the support for
avx2/sse2 isn't yet present (the next commit fixes this).
This is a temporary measure until full sse2/avx2 implementation is
complete, but it works with sse2/avx2
These patches are updates to patches previously posted to the mailing lists,
with some bugs fixed and the reasoning behind some changes expanded on.
This addes macros in postprocess.c that use inline asm for x86,
__builtin_prefetch if using a recent enough gcc compatable compiler, and

This series of patches makes some changes to libpostproc in preperation for
adding
sse2 and avx2 simd versions of some functions. None of the changes should effect
the library in any major way, but they are necessary for future changes.
I've tested

There's still an if, as QP needs to be modified if isColor=0, but it
still removes a unecessary branch.

I can't actually test it since there's a lot of work to be done in
interfacing the asm code to the c code, changing block sizes, changing
the way QP's are delt with, etc. But it assembles, there are warnings
for section redeclarations, and I'm not sure

This patch set contains implementations of various filters from libpostproc,
translated from inline asm (in postprocess_template.c) into seperate yasm files.
In addition support for sse2 and avx2 has been added via the use of the simd
abstraction layer

This change is to allow support for different sized blocks, which will
be necessary for sse and avx. My plan is for the code to still act on
8x8 blocks, but to process multiple 8x8 blocks in parallel when using
sse/avx.
