1. Changed buffer_alloc_sz and frame_size type to size_t.
2. Added a TODO for video resolution limits. On 32 bit systems, the maximum
resolution supported in the encoder is 4k(3840x2160). The malloc() would
fail if encoding >4k video on a 32 bit system.

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%

Frame can be split into rectangular tiles for application of separate
bilateral or Wiener filters per tile. Some variable names changed for
better readability.

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.

This commit separate the frame index of EXT_ARFs' from other frame
types in the ext-refs setting.

It improves the average RD performance by

0.206% in the lowres, and
0.173% in the midres.

The overall gains for the ext-refs compared to the baseline are

5.665% in the lowres, and
4.883% in the midres.

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.
