Use CONFIG_INTERINTRA to properly separate interintra from the basic
ext_inter experiment.
When macro REDUCE_INTERINTRA_MODES is 1, only 4 ii modes are enabled
so as to reduce the complexity overhead.
(Right now the flag is off)

This experiment extends ALT_INTRA by adding two new modes:
smooth horizontal and smooth vertical.

1) block_raster_idx is actually raster order only when tx_size
is TX_4x8.
It's very specific, so we should put it near to the place it's
actually used.

2) Sync the meaning of block_idx on encoder/decoder sides

A simpler interface for intra block prediction

Now that https://aomedia-review.googlesource.com/#/c/6729/
has been merged, build_intra_predictors_for_interintra() is
now redundant, so replace it by a direct call to
av1_predict_intra_block() and remove the old function.

Reset rect_interintra back to 1.

To do this, we need to make the intra predictor take a
BLOCK_SIZE instead of a TX_SIZE. This is because we need to
be able to predict 32x64 and 64x32 blocks, but there is no
TX_32X64 or TX_64X32.

No effect on output or performance.

The word 'pick' is usually used in functions that make decisions where
the bitstream allows multiple legal choices, and not to limit the
bitstream format itself.

BD-rate performance improvement (on top of ext-intra):
derflr  0.22%
hevclr  0.36%
hevcmr  0.48%

Average speed impact on some derf clips is about 40% slower (on
top of ext-intra). Speed improvment is a to-do.

sizes whenever available (for d45/d63), and adds bottom/left edges for
d207.

1. remove prediction mode conversion
2. unified bmode, same for key and non-key frame
3. set I4X4_PRED count for pdf to 0, as I4X4_PRED is no longer
coded ever. It is determined by ref_frame and block partition

This commit changed the encoding and decoding of intra blocks to be
based on transform block. In each prediction block, the intra coding
iterates thorough each transform block based on raster scan order.

This commit also fixed a bug in D135 prediction code.

TODO next:
The RD mode/txfm_size selection should take this into account when
computing RD values.
