[git version control]

x264 | branch: master | Jason Garrett-Glaser <darkshikari at gmail.com> | Mon Dec  8 13:44:23 2008 -0800| [77028cd3671de855affb02ffefe6bbd99ac7816e] | committer: Jason Garrett-Glaser 

Much faster CAVLC residual coding
Use a VLC table for common levelcodes instead of constructing them on-the-spot
Branchless version of i_trailing calculation (2x faster on Nehalem)
Completely remove array_non_zero_count and instead use the count calculated in level/run coding.  Note: this slightly changes output with subme > 7 due to different nonzero counts being stored during qpel RD.
