(1) This patch will allow compound predictions from the same 
    reference;

(2) The code from this patch only takes effect when the sign bias
    values of the two references are allowed to be identical;

(3) A further effort will be taken to combine this effort with
    compound-singleref to finalize a new coding tool for the 
    single reference, compound prediction mode.

Stores the reconstructed luma pixels for each transform block inside a
prediction block. Rectangular transform blocks are supported.

As for RDO, after all the modes have been tested for luma, an extra
encoding is perform in order to store the reconstructed pixel values of
the best mode. These values are then used for RDO on the chromatic
planes.

This unit test was ported from VP9. To prevent the motion vector out of
range bug, added a motion vector unit test. In the 4k video encoding,
always forced to use extreme motion vectors and also encouraged to use
INTER modes. In the decoding, checked if the motion vector was valid,
and also checked the encoder/decoder mismatch.

(1) Remove one parameter of the function - single_newmv as all setups
related to this parameter can be done (mostly already have been done)
before calling into the function;
(2) Remove one unneccessary checking on the mbmi->ref_frame[1] as the
line of code right before it indicates it is always a compound ref
scenario;
(3) Replace all mbmi->ref_frame[] that have been declared as refs[].

Missing features:
* RDOPT (Forced on for certain blocks)
* Any form of border extension
* Non MI sized right and bottom edges
* MV prediction

Present features:
* Force intrabc for some blocks
* Carry intrabc in the bitstream
* Validate DV is causal
* Reconstruct intrabc block assuming border extension is unnecessary

Fixes several bugs in daala-dist, sub8x8 inter mode
with --disable-cb4x4.

Changes on BD-Rate are:
(objective-1-fast, high delay mode, --disalble-cb4x4):

   PSNR | PSNR Cb | PSNR Cr | PSNR HVS |    SSIM | MS SSIM | CIEDE 2000
14.0337 | 13.0132 | 14.6055 |  -3.2030 | -2.2092 | -9.3902 |    10.3399

Additionally, BD-Rate change by daala-dist in enforced MSE mode
which can show the correctness of implementation is

  PSNR | PSNR Cb | PSNR Cr | PSNR HVS |   SSIM | MS SSIM | CIEDE 2000
0.0048 |  0.0789 |  0.0209 |   0.0443 | 0.0137 |  0.0411 |     0.0441

Change-Id: I68ec90c6072aa3564522c2b8e87b62a998cec47c

This changes the behavior of the ext-inter compound modes
as follows:
* NEAREST_NEARESTMV, NEAR_NEARMV, NEW_NEWMV, ZERO_ZEROMV
  work the same as the corresponding compound modes without
  ext-inter
* NEAREST_NEWMV and NEW_NEARESTMV keep their current behavior,
  which is to use the first ref-mv candidate pair for their
  particular reference frames
* NEAR_NEWMV and NEW_NEARMV select between the second, third,
  and fourth candidate pairs.
* NEAREST_NEARMV and NEAR_NEARESTMV use the first candidate
  pair for the NEAREST component and the second, third, or
  fourth candidate pair for the NEAR component.

Also do some minor refactoring and fix compile errors
with --enable-ext-inter --disable-ref-mv
