Jean-Marc Valin 01b7780154 Deringing line buffer no longer depends on holding OD_DERING_VERY_LARGE 
The OD_DERING_VERY_LARGE values are now explicitly copied to the buffer instead
of being read from the line buffer when we're on the edge of the frame. This
will make it possible to make the line buffer 8-bit for non-high-bitdepth.

Urvang Joshi 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
