The equals() method fails, because the parameter "transient_lastDdlTime" is
sometimes off by one. Otherwise, the two objects are entirely equal. I think
the db name, table name, and list of values also ensures equality.

Fixed

The equals() method also fails here, even though the tables are logically
equal. In the case above, "tbl" does not have a PrincipalPrivilegeSet.
"oldTable" has a PrincipalPrivilegeSet, but all of it's fields are set to null.
This discrepancy comes from how we get the tables, but I think they should
still be considered equal.

bq. Summary
bq. -------
bq.
bq. HIVE-2038 introduced the MetaStoreEventListener abstract class that
defines actions to be performed after particular events on a metastore. Improve
upon that class by adding events to be performed on "alter table" and "alter
partition" actions. Also, update the hive metastore to call the appropriate
functions of the listeners when the events happen.

bq. This addresses bug HIVE-2194.
