This commit fixes the 2x2 transform system setups for high bit-
depth setting. It enables the cb4x4 mode to support high bit-depth
process. The coding performance is improved over high bit-depth +

lowres  2.5%
midres  1.2%

This commit allows the dynamic motion vector referencing system to
scale its search range according to the coding block size. This
provides higher search resolution for smaller size coding unit.

The cb4x4 mode improves the compression performance across all the
test sets:

         avg     low    mid    high
lowres   2.8%    2.4%   3.1%   3.0%
midres   1.3%    0.3%   1.8%   2.7%
hdres    0.9%    0.5%   1.4%   1.5%

Use the proper scaling factor to decide if a block is sitting on
the frame border. This refactor does not change the coding
statistics of the code base. It fixes an enc/dec mismatch issue
due to out of boundary memory access in the cb4x4 mode.
