revlog: use raw revisions in revdiff

See the added comment. revdiff is meant to output the raw delta that will be
written to revlog. It should use raw.

test-revlog-raw.py now shows "addgroupcopy test passed", but there is more
to fix.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
