This bit appears in the sequence header. At the moment, it does
nothing, but it will mean that we don't encode (or read) chroma
planes.

This patch adds the flag to the sequence header, and also adds an
encoder option (--monochrome) which enables it. At the moment, this
doesn't do anything except cause the bit to be set correctly in the
header.

The previous code cropped the width and height correctly when
CONFIG_FRAME_SUPERRES was enabled and we were doing scaling, but
didn't do so the rest of the time.

While large_scale_tile = 1, no backward CDF update happens during
encoding. So, no need to update frame contexts at end of frame
encoding.

The transform search set is being determined based on the square
transform size one level below the block size. MRC_DCT is not
included in the transform set for 16x16 so it will be skipped in
the transform search for 32x32 blocks. This change allows it to
be included in the search.
