This corrects a formatting error introduced in:
I1e9d548ce445d29002f0c59ebfd3957a6f15e702
where spaces were used as delimiters instead of tabs.

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 values after right shifts should fit into 32bit int. The commit
fixes MSVC build warning when new-quant is enabled.

When the experiment is ON, we use Paeth predictor instead of TM
predictor.
For derf set, this gives about 0.09% improvement overall, and 0.55%
improvement if all frames are forced to be intra-only.
Also, if the EXT_INTRA experiment is also on, the improvement overall
is 0.056%, and improvement if all frames are forced to be intra-only is
0.465%.

Function ans_read_int() takes int as parameter, this commit uses an
explicit conversion to avoid MSVC building warning.

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
