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.

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%.

  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

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%

Skip checking obmc when regular inter predictor is not so good (the
rd-cost for Y residual is greater than the total rd of the best mode
so far.)

Performance change compared to full rd search:
  +0.006% lowres, -0.056% midres
Encoding time :
  1.14X baseline (was 1.42X)

This will make the code change for a pure ANS experiment manageable.

After porting tile coding from VP9 to VP10, some performance
degradation was seen because of the difference between VP9 and
Vp10 baseline. This patch disabled some features in VP10 while
tile coding is turned on. Also, an encoder control API was added
back for this use case.

Skip filtered intra modes search in inter frame when DC mode is
worse than the best mode so far.

With ext-intra enabled, the overall speed is increased by 20~40%;
performance drop is 0.03% on lowres and 0.05% on midres.

- Added function fidtx4_sse2().
- Turned on vp10_fht4x4_sse2() for these tx types.
- Updated 4x4 unit test for speed/accuracy.
- 4x4 Unit test passed.
- Running 20K times with random numbers for tx type from
  V_DCT to H_FLIPADST, SSE2 against C, speed improves ~46%.

This was broken due the leakage between consecutive CLs.

If configured with --enable-ext-tile, the codec uses an alternative
tile coding syntax in the bitstream. Changes include::
 - The maximum number of tile rows and columns is extended to 1024
   each.
 - The minimum tile width/height is 64 pixels (1 superblock).
 - A tile copy mode is added where a tile directly reuse the coded
   data of a previous tile
 - The meaning of the tile-columns and tile-rows codec parameters are
   overloaded to mean tile-width and tile-height in units of 64
   pixels.
 - All tiles should now be independent, including rows within the
   same columns, so large scale parallel, or independent decoding is
   possible.
 - vpxdec also gained the options to decode only a particular tile,
   tile row, or tile column.

Changes without --enable-ext-tile:
 - All tiles should now be independent, including rows within the
   same columns, so large scale parallel, or independent decoding is
   possible.
 - vpxenc default tile configuration changed to use 1 tile column.
