(1) USE_GUESS_LEVEL = 0: each superblock search and apply best
deblocking filter level. Filter level is transmitted each superblock.

(2) USE_GUESS_LEVEL = 1: use q to guess a filter level for the whole
frame. Only one filter level is transmitted.

I had done only a partial fix before. But updating the costs seems to
make an even bigger improvement to the baseline.

Instead of applying different offsets for each of quadri-split, horizontal split,
vertical split, store the start addresses of src and dst 8x8 blocks in each of
YUV palnes then pass it to distortion compute function for dist-8x8, dist_8x8_yuv().

Also, don't save decoded pixels for 8x8 block in additinal buffer but directly
access the xd->dst buffer. Thus removed the decoded-8x8[8x8] buffer in struct macroblock.

However, this patch does NOT fix the case where dist-8x8's assert fails with
CfL enabled.

This patch updates also the default cdfs for skip mode. It also remove
the unneeded checking on whether the best obtained RD mode aligned
with the skip mode.

This should give a slight speed-up for streams with CDEF disabled,
since it avoids having to test the same for every filter block.

Also, splits the sub_tx_size_map array into inter and intra
in order to enable the new 4:1 transforms for inter and
intra separately.
Includes refactoring such as removing the intra_tx_size_cat_lookup
array since it is unnecessary, and consolidating the
max_txsize_rect_lookup array for convenience.

Currently 4:1 transforms have max 2 split levels:
4:1 -> 1:1 -> 0.5:0.5.

This refactor enables split levels:
4:1 -> 2:1 -> 1:1,

by simply changing the tables in common_data.h.

The actual switch will be made in a subsequent patch.
