Add PageData C type

This adds the C type PageData and makes the existing type Page a
pointer to it.  This follows the usual PostgreSQL C type naming scheme
of Foo/FooData pairs.  (Prior to commit ddbba3aac86, PageData existed
as an unrelated type.)  The type definitions are compatible, so this
doesn't change anything except some of the naming.
