post-proc: deblock filter optimization 1. Algorithm modification: Instead of having same filter threshold for a whole frame, now we allow the thresholds to be adjusted for each macroblock. In current implementation, to avoid excessive blur on background as reported in issue480(http://code.google.com/p/webm/issues/detail?id=480), we reduce the thresholds for skipped macroblocks. 2. SSE2 optimization: As started in issue479(http://code.google.com/p/webm/issues/detail?id=479), the filter calculation was adjusted for better performance. The c code was also modified accordingly. This made the deblock filter 2x faster, and the decoder was 1.2x faster overall. Next, the demacroblock filter will be modified similarly. Change-Id: I05e54c3f580ccd427487d085096b3174f2ab7e86

post-proc: deblock filter optimization 1. Algorithm modification: Instead of having same filter threshold for a whole frame, now we allow the thresholds to be adjusted for each macroblock. In current implementation, to avoid excessive blur on background as reported in issue480(http://code.google.com/p/webm/issues/detail?id=480), we reduce the thresholds for skipped macroblocks. 2. SSE2 optimization: As started in issue479(http://code.google.com/p/webm/issues/detail?id=479), the filter calculation was adjusted for better performance. The c code was also modified accordingly. This made the deblock filter 2x faster, and the decoder was 1.2x faster overall. Next, the demacroblock filter will be modified similarly. Change-Id: I05e54c3f580ccd427487d085096b3174f2ab7e86

nasm: address labels 'rel label' vice 'wrt rip' nasm does not support `label wrt rip', it requires `rel label'. It is still fully compatible with yasm. Provide nasm compatibility. No binary change by this patch with yasm on {x86_64,i686}-fedora13-linux-gnu. Few longer opcodes with nasm on {x86_64,i686}-fedora13-linux-gnu have been checked as safe.
