Bitstream syntax:
For a rectangular inter block, 'rect_tx' flag is sent to indicate if
the biggest rect tx is used. If no, continue to decode regular
recursive tx partition.

Uses an array to map block sizes, y tx sizes, and subsampling
factors to various transform sizes for UV.

This patch completes the global motion experiment
implementation. It modifies the format of the motion
parameters to use the mv union to facilitate faster
copying and checks for parameters equal to 0 that occur
frequently in rdopt. The rd decisions for the global motion experiment
have also been added to rdopt.

The previous ext-refs experiment did not consider the cost of the 2nd
reference frame on mode decision in the compound mode. With the fix,
using Overall PSNR, compared to the previous ext-refs RD performance
before the bug fix, all against the baseline, the improvements are:

"ext-refs" before fix: lowres -5.665%  midres: -4.833%
"ext-refs" after fix:  lowres -5.776%  midres: -5.000%
Improvement by the fix: lowres -0.111%  midres: -0.167%

For rectangular blocks between 8x8 and 32x32, we can now code the
transform size as one bigger than the largest square that fits in
the block (eg, for 16x8, we can code a transform size of 16x16
rather than the previous maximum of 8x8), when this oversized
transform is coded in the bitstream, the codec will use the full
size rectangular transform for that block (eg 16x8 transform in
the above example).

Also fixes a scaling bug in 16x8/8x16 transforms.

rd_pick_palette_intra_sby() method is called only when,
cpi->common.allow_screen_content_tools is on. So, no need to check that
again. We just use an assert() instead to still be safe.

Mostly refactoring, but a very tiny functional change:
Do all rounding in calc_centroids() itself, instead of rounding in two
places inside palette.c

This gives a slight performance improvement for screen content:
0.078% on average.

(1) Key frame: skip filter intra modes whose directional pred
    version is relatively bad (rd >= 1.125 * best_rd)
(2) Inter frame: do not check filter intra modes if best_intra_rd
    >= 1.25 * best_rd

Encoding time overhead is reduced by:
4.9% (9.2%->4.3%, soccer_cif)
Coding gains drop by 0.021% on lowres and by 0.076% on midres

We have renamed following Macros to avoid name confusion:

REFS_PER_FRAME --> INTER_REFS_PER_FRAME
(= ALTREF_FRAME - LAST_FRAME + 1)
MAX_REF_FRAMES --> TOTAL_REFS_PER_FRAME
(= ALTREF_FRAME - INTRA_FRAME + 1)

INTER_REFS_PER_FRAME specifies the maximum number of reference frames
that each Inter frame may use.
TOTAL_REFS_PER_FRAME is equal to INTER_REFS_PER_FRAME + 1, which
counts the INTRA_FRAME.

Further, at the encoder side, since REF_FRAMES specifies the maximum
number of the reference frames that the encoder may store, REF_FRAMES
is usually larger than INTER_REFS_PER_FRAME. For example, in the
ext-refs experiment, REF_FRAMES == 8, which allows the encoder to
store maximum 8 reference frames in the buffer, but
INTER_REFS_PER_FRAME equals to 6, which allows each Inter frame may
use up to 6 frames out of the 8 buffered frames as its references.
Hence, in order to explore the possibility to store more reference
frames in future patches, we modified a couple of array sizes to
accomodate the case that the number of buffered reference frames is
not always equal to the number of the references that are being used
by each Inter frame.
