Implement "ALTER EXTENSION ADD object". 

This is an essential component of making the extension feature usable;
first because it's needed in the process of converting an existing
installation containing "loose" objects of an old contrib module into
the extension-based world, and second because we'll have to use it
in pg_dump --binary-upgrade, as per recent discussion.

Loosely based on part of Dimitri Fontaine's ALTER EXTENSION UPGRADE
patch.

<para>
The kinds of SQL objects that can be members of an extension are shown in
the description of <xref linkend="sql-alterextension">. Notably, objects
that are database-cluster-wide, such as databases, roles, and tablespaces,
cannot be extension members since an extension is only known within one
database. (Although an extension script is not prohibited from creating
such objects, if it does so they will not be tracked as part of the
extension.) Also notice that while a table can be a member of an
extension, its subsidiary objects such as indexes are not directly
considered members of the extension.
