Subject: - move lock functions to a full blown module - handle get_exclusive
 and release_exclusive on existing lock,   *but* don't use it for now! (not
 useful) - remove urpmi_db locking from add_medium and update_media - move
 rpm_db locking into _read_cachedir_pubkey - update_media: restrict rpm_db
 exclusive locking to parse_pubkeys - urpmi: move locking rpm_db near its use
 - handle lock directly in urpmi.addmedia, urpmi.update, urpme, urpmf - log
 locking/unlocking
