5b53d20c68 Put progressive JPEG AC decode logic back the way I wrote it originally (I changed it to match jpgd when I was trying to figure out why it didn't work); 
add STBI__ prefixes to internal SCAN_ enum;
strip unused function arguments for progressive funcs;
tweak release notes;
forget to git commit frequently so these would all be in their own commits;

support using inline asm for cpuid

YCbCr:
  switch SSE code to constants that match old C;
  create C version that is same as SSE;

c6a3235995 stb_image: IDCT kernel func ptr in stbi__jpeg 
I want to support SSE2 kernels that auto-detect. If implemented
using globals, this would trigger thread race checkers if stb_image
was used in multiple threads. Just make the kernels be explicitly
per-stbi__jpeg to avoid this.

(This commit is the first step in replacing existing STBI_SIMD
functionality.)

518306517c stb_image: JPEG dequant in decode_block not IDCT. 
Inside decode_block, we're still sparse, and we can use that
sparsity pattern without doing extra work to discover it.
