Adding get_uv_tx_size_impl() with tx size selection logic, rewriting
get_uv_tx_size().

In deciding the transform size for a given block in a given TX_MODE.

Adding temporary "typedef BLOCK_SIZE BLOCK_SIZE_TYPE" which will go away
after encoder's patch.

Change-Id: I06ec6a6f079401439843ec981d1496234fd7775c

There will be another change set to rename BLOCK_SIZE_TYPE enum to
BLOCK_SIZE.

Change-Id: I8d1dfc873d6186fa5e554262f5169e929978085e

Removing the old one bsize_from_dim_lookup. Now we have a way to determine
block size for plane using its subsampling values (ss_size_lookup). And
then we can find the number of pixels in the block (num_pels_log2_lookup).

Cons bw/bh parms that should have been const. Additional formatting.

Change-Id: Icd36a5c9dc17dadd7284315ac0d6fef1a565ca16

Adds a function to compute source variance for various
sb_types to be used for pruning mode and partition searches.
[The existing activity measure function is currently specialized
for only 16x16 MBs and needs to be updated].

many structures use bw and bh and they have different meanings.   This cl attempts
to start this clean up and remove unneccessary 2 step look up log and then
shift operations...

also removed partition type multiple operation code in bitstream.c.

Change-Id: I7e03e552bdfc0939738e430862e3073d30fdd5db

Implements some of the helper functions more efficiently with
lookups rathers than branches. Modeling function is consolidated
to reduce some computations.

Also merged the two enums BLOCK_SIZE_TYPES and BlockSize into
one because there is no need to keep them separate (even though
the semantics are a little different).

No bitstream or output change.

About 0.5% speedup

converted to lookup to avoid unnecessary code

Change-Id: I2ee6a01f06984cc2c4ba74b3fffd215318f749d2

    Replace case statement with lookup.
    Small speed gain at low speed settings but at speed 2+ where the
    number of motion searches etc. falls the impact rises to ~3-4%.

Changes 'The VP8 project' to 'The WebM project', for consistency
with other webmproject.org repositories.

Fixes issue #97.

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