- Remove rpmquery and rpmverify manuals for now, the functionality
didn't get split to separate binaries afterall and the manpages
were in a rather bad shape afterall.
- Add some missing options, remove no longer existing options
- Remove rpmdb, rpmkeys, rpmsign and rpmspec related switches from
man rpm manual, add them to the "see also"-section instead
- Adjust database file list on main rpm manual, remove it from rpmbuild man.
