# Creates a database with the given SCHEMA, starts an ovsdb-server on
# that database, and runs each of the TRANSACTIONS (which should be a
# quoted list of quoted strings) against it with ovsdb-client one at a
# time.
#
# Checks that the overall output is OUTPUT, but UUIDs in the output
# are replaced by markers of the form <N> where N is a number.  The
# first unique UUID is replaced by <0>, the next by <1>, and so on.
# If a given UUID appears more than once it is always replaced by the
# same marker.
