xdiff: drop XDL_EMIT_COMMONjk/no-diff-emit-common
There are no more callers that use this mode, and none likely to be added (as our xdl_merge() eliminates the common use of it for generating 3-way merge bases). This is effectively a revert of a9ed376 (xdiff: generate "anti-diffs" aka what is common to two files, 2006-06-28), though of course trying to revert that ancient commit directly produces many textual conflicts.
