optimize VP6 decoding for ARM

Registered by Alexander Sack on 2010-10-20

 * Review VP6 open-source decoders
 * Define test cases and ensure requirements are taking account in free test content spec
 * document performance hot spot identification mechanisms
 * create test-harness and keep track of performance numbers over time
 * hand optimize VP6 decoders working together with upstream community
