Most of these were picked up in the previous commit (prefix change from
vp8_ to vp9_), but I'm pushing this separately so that it's easier to
review.

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%.

As suggested by Paul, this commit separate the subpel refmv selection
into a separate experiment. It also changed a couple variable names
to better reflect the nature of the variables.

Also include the correct header in ratectrl.c so it picks up these
function prototypes.

This way, the code is not compiled in by default, thus decreasing
overall binary size.

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.
