Converted the forward and inverse transforms to integer forms.

Modify #define TEST_INT 1/0
in the code to call integer/float version of transforms.

The tests showed that average OVERALL PSNR loss was less than 0.1%.

Previously, in evaluating reference motion vectors, MVs are always
rounded to integer pixel position and SADs are calculated.  This
commit takes into account the subpixel portion of the mvs, and uses
bilinear interpolation to produce reference pixel values in subpixel
postions. In addition, SSE is used in place of SAD. Pixels used are
16x2 above and 2x16 to the left.

This commmit intends to test the potential of this line of work in
term of compression improvement, obviously, the change would increase
decoder complexity significantly.

Coding and costing of mv reference signal.

Issues in updating MV ref with COMPANDED_MVREF_THRESH
to be resolved. Ideally the MV precision should be defined based
on absolute MV magnitude not as now the MV ref magnitude.

Update to mv counts moved into bitstream.c because otherwise
if the motion reference is changed at the last minute the encoder
and decoder get out of step in terms of the counts used to update
entropy probs.

Code working on a few test clips but no results yet re benefit vs
signaling cost and no tuning of red loop to test lower cost alternatives
based on the available reference values.

Patch 3. Added check to make sure we don't pick a reference
that would give rise to an uncodeable / out of range residual.

Patch 6-7: Attempt to rebase. OK to submit but best to leave flag off for now.

Patch 9. Remove print no longer needed.

Refactor per-transform copy & paste into a common function
update_coef_probs_common() and read_coef_probs_common(). The dry-run and
bit-writing loops in the encoder are still obvious candidates to be made
common, but they start to diverge a bit in the next commit, so are left
as-is for now.

There is a macro DEFAULT_INTERP_FILTER defined in encoder/onyx_if.c that
is set as EIGHTTAP for now - so SWITCHABLE is not really used. Ideally,
this should be SWITCHABLE but that would make the encoder quite a bit slower.
We will change the default filter to SWITCHABLE once we find a faster way to
search for switchable filters.
