This new coding tool is targeted to complete following two tasks:
(1) Remove the inter mode NEWFROMNEARMV;
(2) Add new inter coding modes that provide compound prediction but
    using single reference frame - initially NEAREST_NEARMV from
    single reference.

The resizing functions in resize.h and resize.c are useful for the
frame super-res experiment. These functions will be needed in both the
encoder and decoder, so the files have been moved into av1/common.

The SSE3 convolve functions do not work when scaling is involved. If
either x_step_q4 or y_step_q4 is not 16 scaling will occur and an assert
fails.

This patch creates a C version of av1_convolve, av1_convolve_c. This
function in turn calls all C versions of what av1_convolve calls. New C
versions of these called functions have been created where needed and
the same for the functions they call. This means that when scaling is
enabled no asserts fail. av1_convolve_c is called instead of
av1_convolve when x_step_q4 or y_step_q4 is not 16.

1) block_raster_idx is actually raster order only when tx_size
is TX_4x8.
It's very specific, so we should put it near to the place it's
actually used.

2) Sync the meaning of block_idx on encoder/decoder sides

The loop filter parameters change due to many experiments. The
multi-thread loop filter is built on certain assumptions that would
require changes in many table contents. Temporarily disable the
multi-thread loop filter pass and only maintain the single frame
reference during the development process.

Adds an option to disable warp when obmc is used with a
warped motion neighbor.
This change will reduce the line buffer requirement for
mode/mv information since the warping parameters no longer
need to be stored.

Instead of using inter/intra to determine the dst buffer has
residue or not, we use dst_has_residue.

This will provide us more flexibility to do experiment.

This CL actually makes the code more complicated but it will allow
us to break the framework of searching tx_size with fixed tx_type

I will find a way to simplify the code later.

This function was incorrectly using transform width instead of height.
The bug wasn't caught yet, because all calls to this function currently
use square transform sizes only.
