Fix Debian package build complaints.

Apply the patches printed out when the Debian package build complains,
and then remove the #MISSING indications that correspond to routines we
don't export outside the library (either because we don't declare them
as exported outside the library, because they've been removed, or
because they've been moved to another library).
