Avoid buffer overflow in case of such new experiments as
128 x 128 superblock size.

Change-Id: Ib775f3925a85fc87227c0ddd9b6a6110a12ef196

Fixes an issue with rectangular inter-intra blocks.
Includes various other refactoring and cleanups to enable fast mixing
of inter and intra predictors.
Uses only the best single inter reference so far for the inter-intra
search.

About 30% speed-up with a 0.1% hit in performance.

This is part one of overhauling on the ext-inter experiment. To be
continued in subsequent patches.

If --enable-ext-partition is used at build time, the superblock size
(sometimes also referred to as coding unit (CU) size) is extended to
128x128 pixels.

Compute the rate-distortion cost for sub8x8 blocks with integer
motion vectors.

Change-Id: I7dc034fcc4bec3850f26d1f9ae0595c91df1137e

Improve the readability in the related rate-distortion optimization
search control function of sub8x8 blocks.

Change-Id: I7f7456bf40a98aa5146abfe0488cda745b84d899

This commit makes the sub8x8 block to use its nearest neighbor's
motion vector as predicted motion vector for NEWMV mode. It improves
the coding performance by 0.12%.

* changes:
  Add pluggable bitwriters.
  Add pluggable bitreaders.

Moved the API patch from NextGen to NextGenv2 and also added this
API to VP10. An example was included. To try it, for example, run
the following command:
$ examples/vpx_cx_set_ref vp10 352 288 in.yuv out.ivf 4 30

breaks Android build and causes valgrind failures in the examples

Change-Id: Ie13ceed2f9f8970af87339b807032a52083f27fe

This patch fixes 2 issues in Palette mode:
1. More memory is needed in PALETTE_BUFFER for 444 video format.
2. A merge issue caused by

No need to do avoid shortcuts when all we are testing is the superframe
syntax. Decreases the run time up the VP10 version of the test from 22
seconds to 3 seconds on my machine.

- Wrote function: fidtx8_sse2() and fidtx16_sse2().
- Turned on vp10_fht8x8_sse2()/vp10_fht16x16_sse2() for new types.
- Updated 8x8/16x16 unit tests for accuracy/speed.
- Running 20K times with random numbers and getting through
  tx type from V_DCT to H_FLIPADST, SSE2 speed improvement:
  8x8: ~131%
  16x16: ~66%
