Directly call c functions, otherwise when EXT_TX is enabled, hybrid
transform other than combination of DCT/ADST has not been implemented, thus
will cause assertion failures in the switch loops in vp10_fhtnxn_msa() and
vp10_ihtnxn_nxn_add_msa().

The combination of the two experiments improves the compression
performance gains:

lowres 2.5%
midres 2.1%

When the prediction residuals are all zero, reset the coeff rate
cost and the distortion value to be zero. This change doesn't affect
lowres set significantly, but improves several clips in the midres
set, like sintel_480p and mobisode2_480p, by a few percents. The
average performance for midres set is improved by 0.2%.

Use int64_t type for distortion. This avoids integer overflow
issues in the trellis optimization function in high bit-depth
settings.

- Use int32_t instead of int in vpx_obmc{variance,sad} functions
- Remove weigthed_src and obmc mask strides and assume contiguous
  buffers. These inputs can always be packed as contiguous arrays.

Originally we need to send the refresh flag and the virtual indices
mapping for the reference frame buffer update for show_existing_frame to
have the BWDREF_FRAME replace the LAST_FRAME.

To remove sending this information, we update the the virtual indices
of the reference frame buffer after the last_bipred_frame is encoded,
and therefore the decoder will receive the updated reference mapping
at the next non-show-existing frame.

As a result, we can save 4 bytes per show-existing frame, and get 0.12,
0.2, and 0.07 BDRATE improvement in lowres, derf, and midref test set
respectively.

Reject ext-inter compound modes before doing full rate distortion
evaluation, if the corresponding single reference modes had a lower
modelled RD.

ext-inter speedup up to TBD.

Coding performance: TBD
