a9336328d4 Make recursive txfm encoding process support rectangular tx_size 
This commit makes the encoding process of the recursive transform
block partition support both rectangular and square transform block
sizes as the starting point. If the coding block size is rectangular,
it would allow the transform block size to start from the largest
rectangular transform size, and recursive parse to the selected
coding sizes.

8b5380ac77 Remove redundant config flags from get_entropy_context 
The rectangular transform syntax is by default supported, hence
no need to put it under the experimental flag. This does not change
the coding statistics.

a9e96d4000 Disable upsampled references for resolutions above 1080p. 
Upsampled references currently increase the size of references by
64 times. This patch limits the memory used by the encoder to
about 3GB when encoding high bit depth content.

This should be re-evaluated in the future, if doing 8-tap
resampling in the motion search becomes reasonably fast, or if
the upsampled references are reduced in size (by omitting some
subpel positions and interpolating them instead).
