The counts didn't take usehp into account, which means that if the
scope of the refmv is too large for the hp bit to be coded, the value
(always 1) is still included in the stats. Therefore, the final
counts will not reflect the entropy of the coded bits, but rather the
entropy of the combination of coded bits and the implied value (which
is always 1). Fix that by only including counts if the hp bit is
actually coded.

See issue 1060.

See issue 1030. The value of frame_parallel_decoding_mode was ignored
in vp9 if refresh_frame_context was 0, so instead make it a 3-member
enum where the dependency is obviously stated.

In vp9, [0] and [1] had identical meaning, so merge them into a
single value. Make it impossible to code RESET_FRAME_CONTEXT_NONE
for intra_only frames, since that is a non-sensical combination.
