Implement CREATE/DROP OPERATOR CLASS. Work still remains: need more

documentation (xindex.sgml should be rewritten), need to teach pg_dump
about it, need to update contrib modules that currently build pg_opclass
entries by hand.  Original patch by Bill Studenmund, grammar adjustments
and general update for 7.3 by Tom Lane.
