The gm parameters need to have WARPED_PRECISION_BITS precision
until they are written to the bitstream because functions in
reconinter use these parameters before they are written to
the bitstream. Previously, the parameters weren't being converted
to WARPED_PRECISION_BITS until they were read from the bitstream
which causes an encode/decode mismatch.

Currently nothing is implemented to compute GM parameters, this
just adds the capability to send them in the bitstream if they
were computed. Still need to implement the reconstruction
based on the parameters in reconinter.

This commit re-works the reference motion vector stack process
and make it support extended context set. It unifies reference
motion vector checking process for row and column scan, as well as
for single block scan.

This commit ports the motion vector stack from motion field
analyzer to the encoding and decoding pipeline.

Adds a new interpolation experiment.
Improves entropy coding to send the filter type only if
the motion vectors have subpel components.
Adds one new 8-tap smooth filter, and tweaks the others.
derflr: +0.695%
hevcmr: +0.305%
About 5% encode slowdown. No visible impact for decoding.
Also makes the interpolation framework flexible to support both
strictly interpolating filters as well as non-interpolating
filters that filter integer offsets. This is mainly for
further experimentation and if not found useful the code will
be removed.
