Adding plane type check condition because it was always used outside of
get_tx_type_{4x4, 8x8, 16x16}.

Counts are separate from frame context. We have several frame contexts but
need only one copy of all counts.

The struct optimize_block_args is defined same as encode_b_args.
Remove this redundant definition, and use encode_b_args consistently.

Several consecutive for loops executed over the same
index range, so I rolled them into one.

All filters are interpolating now, so we don't need this array, all
values from this array are evaluated to true.

The xform_quant() module is only used by inter modes, hence removing
the redundant switches therein conditioned on tx_type.

When all the transform coefficients were quantized to zero, skip
the inverse transform operation. For bus_cif at 1000 kbps, the
runtime goes from 154967ms -> 149842ms, i.e., about 3% speed-up,
at speed 0.

many structures use bw and bh and they have different meanings.   This cl attempts
to start this clean up and remove unneccessary 2 step look up log and then
shift operations...

also removed partition type multiple operation code in bitstream.c.

Renamed:
  MAX_MB_SEGMENTS to MAX_SEGMENTS
  MB_SEG_TREE_PROBS to SEG_TREE_PROBS

The minimum unit for segmentation in the segment map
is now 8x8 so it is misleading to use MB_ as macro-block
traditionally refers to a 16x16 region.

Try and cut down the cycle count by rearranging the instructions
so there are less stalls.

4x4:    163 ->  123 cycles (33% faster)
8x8:    491 ->  399 cycles (23% faster)
16x16: 1889 -> 1763 cycles (7% faster)
32x32: 8311 -> 8180 cycles (1.6% faster)

Overall encoding time of first 50 frames of bus (speed 0) @ 1500kbps
goes from 1min4.33 to 1min3.00, i.e. 2.11% faster.
