Implement types regprocedure, regoper, regoperator, regclass, regtype

per pghackers discussion. Add some more typsanity tests, and clean up some problems exposed thereby (broken or missing array types for some built-in types). Also, clean up loose ends from unknownin/out patch.

+
+   <para>
+    Object identifiers (OIDs) are used internally by
+    <productname>PostgreSQL</productname> as primary keys for various system
+    tables.  Also, an OID system column is added to user-created tables
+    (unless <literal>WITHOUT OIDS</> is specified at table creation time).
+    Type <type>oid</> represents an object identifier.  There are also
+    several aliases for <type>oid</>: <type>regproc</>, <type>regprocedure</>,
+    <type>regoper</>, <type>regoperator</>, <type>regclass</>,
+    and <type>regtype</>.
+   </para>
+
+   <para>
+    The <type>oid</> type is currently implemented as an unsigned four-byte
+    integer.
+    Therefore, it is not large enough to provide database-wide uniqueness
+    in large databases, or even in large individual tables.  So, using a
+    user-created table's OID column as a primary key is discouraged.
+    OIDs are best used only for references to system tables.
+   </para>
+
+   <para>
+    The <type>oid</> type itself has few operations beyond comparison
+    (which is implemented as unsigned comparison).  It can be cast to
+    integer, however, and then manipulated using the standard integer
+    operators.  (Beware of possible signed-versus-unsigned confusion
+    if you do this.)
+   </para>
+
+   <para>
+    The  <type>oid</> alias types have no operations of their own except
+    for specialized input and output routines.  These routines are able
+    to accept and display symbolic names for system objects, rather than
+    the raw numeric value that type <type>oid</> would use.  The alias
+    types allow simplified lookup of OID values for objects: for example,
+    one may write <literal>'mytable'::regclass</> to get the OID of table
+    <literal>mytable</>, rather than <literal>SELECT oid FROM pg_class WHERE
+    relname = 'mytable'</>.  (In reality, a much more complicated SELECT would
+    be needed to deal with selecting the right OID when there are multiple
+    tables named <literal>mytable</> in different schemas.)

+    All of the alias types accept schema-qualified names, and will

+    The <type>regproc</> and <type>regoper</> alias types will only
+    accept input names that are unique (not overloaded), so they are
+    of limited use; for most uses <type>regprocedure</> or
+    <type>regoperator</> is more appropriate.  For <type>regoperator</>,
+    unary operators are identified by writing NONE for the unused
+    operand.
