* trustdb.c (clean_uids_from_key): Don't keep a valid selfsig around

Browse Source 
when compacting a uid.  There is no reason to make an attacker's job
easier - this way they only have a revocation which is useless in
bringing the uid back.

* keydb.h, kbnode.c (undelete_kbnode): Removed.  No longer needed.

* import.c (chk_self_sigs): Allow a uid revocation to be enough to
allow importing a particular uid (no self sig needed).  This allows
importing compacted uids.
