Adding xd->up_available as additional check for above context.

Also some further simplification following removal
of top node code.

There is an issue in regards to the shared file vp8cx.h
in regard to the roi_map as this interface assumes that
there are only 4 segments. I have left the value here as
4 for now meaning that the roi_map interface is broken
for VP9.

Note that this change would have been easier if I hadn't
had to search for hard wire instances of the number 4
and <= 3.

Remove top node optimization.
The improvement this gives is not sufficient to justify
the extra complexity.

This data is fixed at the MB level, so move it to the common part
of MACROBLOCK.

Quantizers can vary per plane, but not per block. Move these values to
the per-plane part of MACROBLOCK.

Lookup the data per-plane from the MACROBLOCK struct.

This commit moves the coeff storage from the MACROBLOCK struct to its
per-plane part. The next commit will remove the coeff member from the
BLOCK structure so that it is consistently accessed per-plane.

Also refactors vp9_sb_block_error_c and vp9_sb_uv_block_error_c to be
variable subsampling aware.

This commit enables rectangular block prediction of compound
inter-intra mode. It combines the mb/sb32/sb64 prediction functions
into a unified version with configurable block width and height.
This fixes the enc/dec mismatch of the codebase when
comp-interintra-pred is enabled.

* changes:
  Make some sb_type comparisons independent of literal enum values.
  Make loopfilter aware of rectangular blocks.

The variable gf_active_ptr is not used anywhere, hence is removed.

Also use explicitely named enum values in sb_type comparisons, rather
than relying on absolute integer values, because enum values may
change in the future.

First in a series of commits making certain MACROBLOCK members
addressable per-plane. This commit also refactors the block subtraction
functions vp9_subtract_b, vp9_subtract_sby_c, etc to be
loops-over-planes and variable subsampling aware.

Removing this experiment for now, since it has been broken with
the latest code changes.
