tile_col in the decoding modules.

This value is a global frame-level flag, not a macroblock-level.

That makes decoder and encoder (only bitstream writing part) a little bit
simpler and faster. Moving get_sb_index() function to the encoder.

This should make parallel tiles decoding easier to implement.

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

We already have itxm_add member in MACROBLOCKD structure. Both
inv_txm4x4_1_add and inv_txm4x4_add are just its special cases for
different eob values. But eob logic is already implemented in
vp9_iwht4x4_add and vp9_idct4x4_add (that's why also removing
inverse_transform_b_4x4_add).

Moving INTERPOLATIONFILTERTYPE enum and subpix_fn_table struct to
vp9_filter.h. Adding convenient typedef for subpel kernels.

Function vp9_setup_interp_filters() besides setting xd->subpix.filter_x &
xd->subpix.filter_y has a side effect of also setting scale factors. This
is not required inside decode_modes_b() because scale factors have been
already set by set_ref() calls. That's why replacing
vp9_setup_interp_filters() call with newly created vp9_get_filter_kernel()
call. The behavior of vp9_setup_interp_filters() is unchanged (it
is used from the encoder).

This commit defines b_mode_info as a struct type. This will allow

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 macro block mode info context originally contained an
entry for each 16x16 macroblock. In VP9 each entry refers
to an 8x8 region not a macro block, so the naming is misleading.

This first stage clean up changes the names of 3 entries in the
structure to remove the mb_ prefix.

TODO clean up the nomenclature more widely in respect of
mbmi and bmi.
