19987dcbfa Faster vp8_default_coef_probs
Copies from a generated table instead of building the
default coeff probabilities during runtime.

a25f6a9c88 Moved vp8_encode_bool into boolhuff.h
allowing the compiler to inline this function.  For real-time
encodes, this gave a boost of 1% to 2.5%, depending on the
speed setting.

b32da7c3da Use MAX_ENTROPY_TOKENS and ENTROPY_NODES more consistently
There were many instances in the code of vp8_coef_tokens and
vp8_coef_tokens-1, which was a preprocessor macro despite the naming
convention. Replace these with MAX_ENTROPY_TOKENS and ENTROPY_NODES,
respectively.

4cb0ebe5b2 Adding support for independent partitions

contexts.

825adc464f shrink TOKENEXTRA and vp8_extra_bit_struct
Per John's previous change, shrink TOKENEXTRA from 20 to 8 bytes
original: b7b1e6fb
reverted: 41f4458a

Also drop unused field from vp8_extra_bit_struct

Update ARM ASM to deal with this change. In particular, Extra is signed
and needs to be sign-extended when loaded.

additional pushing and popping of registers that was not needed.

94c52e4da8 cosmetics: trim trailing whitespace
When the license headers were updated, they accidentally contained
trailing whitespace, so unfortunately we have to touch all the files
again.
