Convert assorted internal-ish datatypes, namely aclitemin, int2vectorin, oidin, oidvectorin, pg_lsn_in, pg_snapshot_in, and tidin to the new style. (Some others you might expect to find in this group, such as cidin and xidin, need no changes because they never throw errors at all. That seems a little cheesy ... but it is not in the charter of this patch series to add new error conditions.)
