This move is done to have all compressed header reading functions in one
place. Moved functions:
  read_switchable_interp_probs
  read_inter_mode_probs
  read_comp_pred_mode
  read_comp_pred
  update_mv
  read_mv_probs

This commit uses left_available flag to decide if the left mode_info
struct is available for left_block_mode. As discussed with James
Zern (jzern@), this prevents the codec from fetching mode_info from
blocks in the left tile, which although effectively not used might
present concerns for multi-threaded tile decoding.

This is NOT a bit-stream change.

The only case where they were intentionally pointing to different
structures was in mbgraph, and this didn't have the expected behavior
because both of these pointers are used interchangeably through the code

Updated the encoder to handle frames that are coded
intra-only. Intra-only frames must be non-showable,
that is, the "show frame" flag must be set to 0 in
the frame header.

Tested by forcing the ARF frames to be coded intra-
only.

Note: The rate control code will need to be modified
to account for intra-only frames better than they
are currently handled.

The probability model used to code prediction mode is conditioned
on the immediate above and left 8x8 blocks' prediction modes. When
the above/left block is coded in sub8x8 mode, we use the prediction
mode of the bottom-right sub8x8 block as the reference to generate
the context.

This commit moves the update of mbmi.mode out of the sub8x8 decoding
loop, hence removing redundant update steps and keeping the bottom-
right block's mode for the decoding process of next blocks.

mode_info_context was stored as a grid of MODE_INFO structs.
The grid now constists of pointers to MODE_INFO structs.  The
MODE_INFO structs are now stored as a stream (decoder only),
eliminating unnecessary copies and is a little more cache
friendly.

mode_info_context was stored as a grid of MODE_INFO structs.
The grid now constists of a pointer to a MODE_INFO struct and
a "in the image" flag.  The MODE_INFO structs are now stored
as a stream, eliminating unnecessary copies and is a little
more cache friendly.

For the test clips used, the decoder performance improved
by ~4.3% (1080p) and ~9.7% (720p).

Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p)
and 5.9% (720p).

The segment feature SEG_LVL_SKIP requires the prediction unit size
to be at least BLOCK_8X8. This commit makes the requirement to be
explicit. This is to prevent future encoder implementations from
making wrong choices.
