Support arrays of composite types, including the rowtypes of regular tables

and views (but not system catalogs, nor sequences or toast tables).  Get rid
of the hardwired convention that a type's array type is named exactly "_type",
instead using a new column pg_type.typarray to provide the linkage.  (It still
will be named "_type", though, except in odd corner cases such as
maximum-length type names.)

Along the way, make tracking of owner and schema dependencies for types more
uniform: a type directly created by the user has these dependencies, while a
table rowtype or auto-generated array type does not have them, but depends on
its parent object instead.
