Show 'Required By' in -Sii output
Just as we do in -Qi, we can compute required by information for sync database packages. The behavior seems sane; for a given package, the -Sii required by will show all packages in *any* sync database that require it. Implements FS#16244. Signed-off-by: Dan McGee <dan@archlinux.org>
