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[].

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

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

* Refactor write_inter_mode and cost_mv_ref slightly

* In handle_inter_mode: When discount_newmv_test returns 1,
  ext-inter is enabled, and we're costing up a compound mode,
  we would previously call cost_mv_ref with mode=NEARESTMV and
  comp_pred=1. But this is inconsistent when ext-inter is enabled!

  Fix this by changing the behaviour of cost_mv_ref to (effectively)
  derive comp_pred from the mode passed in, and switch to
  mode=NEAREST_NEARESTMV in the above case.

* Fix incorrect motion vector costing for some compound modes

* Fix a case where compound blocks were mis-costed. This primarily
  affects ext-inter *without* wedge or compound-segment enabled,
  but should still have some small impact when those experiments
  are enabled.

  The cause of this is that we only spend bits to send the
  interinter compound type if is_any_masked_compound_used(bsize)
  returns true. But the rdopt loop forgot to check this condition
  in one case.

1) Check if tx_type is valid in get_tx_type

2) Remove scan_order from rdcost_block_args
When lv_map is on, scan_order depends on tx_type but tx_type is
not decided before entering block_rd_txfm yet. Therefore
assigning a scan_order into rdcost_block_args and then passing it
into block_rd_txfm will cause error.

3) Pass correct index into intra_mode_to_tx_type_context in
get_tx_type

This CL doesn't affect baseline/supertx's stats.
