add WebPWorkerExecute() for convenient bypass
This is mainly for re-using the worker structs without using the
thread.

* changes:
Use a separate MODE_INFO stream for each tile column
Get rid of "this_mi", use "mi_8x8[0]" everywhere instead
Make the static_segmentation feature work again
The only case where they were intentionally pointing to different
structures was in mbgraph, and this didn't have the expected behavior
because both of these pointers are used interchangeably through the code

Moving code that gets band_translate array from get_scan_and_band()
function to get_band_translate() function. Renaming get_scan_and_band() to
get_scan().

This should be similar to what x264 does with --aq-mode 1.
It works well with clips like parkjoy and touhou
(http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv).
At low bitrates, the segmentation signaling overhead may negate the
benefits of this feature.
(PGW) Default changed to feature OFF to allow provisional merge.

Updated the encoder to handle frames that are coded
intra-only. Intra-only frames must be non-showable,
that is, the "show frame" flag must be set to 0 in
the frame header.
Tested by forcing the ARF frames to be coded intra-
only.
Note: The rate control code will need to be modified
to account for intra-only frames better than they
are currently handled.

Remove the semicolon in the definition of vp9_zero macro. Make all
the use cases of vp9_zero of consistent format.

The commit added check to make sure no invalid memory access even when
the decoder instance is never initialized.
Change-Id: I4da343d0b3c78c27777ac7f5ce7688562c69f0c5
For bad input data, the decoder may access the array out of bounds. The
commit added clamp to prevent such out of bound access

Use the zcoeff_blk buffer of PICK_MODE_CONTEXT to store the indexes
of all-zero-coeff block of the current best mode. Remove the temporary
buffer best_zcoeff_blk defined in the rate-distortion optimization
loop. This improves the speed performance by about 0.5% in all speed
settings.
