This code assumes that the 'logical_port' column in Bindings is always
a UUID.  I guess maybe that's what we're using in OpenStack, but it
would be more general if we did not assume a particular format.  I
don't think that's really harder--it's just a matter of hashing and
comparing strings instead of UUIDs.  I don't think you even need to
xstrdup() and free() the string values since you're not keeping them
across an ovsdb_idl_run().
