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.
