      Fix and enable I_PCM macroblock support · 6b4ad5f5
      Fiona Glaser authored 
      In RD mode, always consider PCM as a macroblock mode possibility
Fix bitstream writing for PCM blocks in CAVLC and CABAC, and a few other minor changes to make PCM work.
PCM macroblocks improve compression at very low QPs (1-5) and in lossless mode.

      Convert NNZ to raster order and other optimizations · ec3d0955
      Fiona Glaser authored 
      Converting NNZ to raster order simplifies a lot of the load/store code and allows more use of write-combining.
More use of write-combining throughout load/save code in common/macroblock.c
GCC has aliasing issues in the case of stores to 8-bit heap-allocated arrays; dereferencing the pointer once avoids this problem and significantly increases performance.
More manual loop unrolling and such.
Move all packXtoY functions to macroblock.h so any function can use them.
Add pack8to32.
Minor optimizations to encoder/macroblock.c

      2x faster quant. 2% overall. · 10265a0c
      Loren Merritt authored 
      side effects:
not bit-identical to the previous algorithm.
while the new algorithm covers a wider range of cqms than the previous one did,
I couldn't find a good way to fallback to a general version for the extreme
cqms. so now it refuses to encode extreme cqms instead of just being slower.
lays a framework for custom deadzone matrices, though I didn't add an api.
