With this patch affine or homography models can be enabled
by simply changing the value of the GLOBAL_TRANS_TYPES
macro in common/mv.h to 4 and 5 respectively. Currently
it is left at supporting only rotzoom. There is a small
gain with enabling affine.
Also refactors costing to change based on the model type.

Improves results for videos that have a strong global motion.

This fixes a rare encode/decode mismatch due to inconsistent
rounding of NEARMV/NEARESTMV vs. ZEROMV motion vectors when both
global motion and ref-mv are enabled.

Replace the int_mv storage in the ref_mv_stack struct with unit8_t
integer to indicate the prediction difference level.

To facilitate further experiments.
Fixes border, uses standard interpolation filters for
translation only global model, and some refactoring.

After https://aomedia-review.googlesource.com/#/c/5589/ ,
the Global_Motion_Params and GLOBAL_MOTION_TYPE types
are redundant, and can be removed in favour of
WarpedMotionParams and TransformationType respectively.

This allows for a clean subtraction of 1 along the transform
matrix diagonal and also makes the order of the parameter list
a little more intuitive.

This patch completes the global motion experiment
implementation. It modifies the format of the motion
parameters to use the mv union to facilitate faster
copying and checks for parameters equal to 0 that occur
frequently in rdopt. The rd decisions for the global motion experiment
have also been added to rdopt.
