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.

46003149e5 Fix a merge bug between dual_filter and sub8x8mc 
The function module in inter_predictor() has been changed to
universally support arbitrary block size inter prediction. Hence
sub8x8mc can be a standalone experiment now.

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.

eb54e0cde8 Revert of "Mark bogus palette color probabilities as zero". 
Reverted commit: f8306bfdc (with some changes).

Reason: This was triggering an assert in debug build because of zero
probability values. So, using an "UNUSED_PROB" macro to replace these to
retain clarity.

Assertion failure can be reproduced as follows:

$ make clean; extra_cflags='-O0 -g -fno-inline' ../../configure
--enable-debug --enable-experimental --enable-palette && make -j 16

$ ./aomenc -D --codec=av1 ~/videos/screen_content_set/gimp.y4m -o
/tmp/foo.webm --tune-content=screen --limit=50
