* misc.c (pull_in_libs): Dead code. Removed.

* sig-check.c (check_revocation_keys): Comments.

* getkey.c (merge_selfsigs_main): Don't bother to check designated revoker
sigs if the key is already revoked.

* packet.h, getkey.c (merge_selfsigs_main): New "maybe_revoked" flag on
PKs.  It is set when there is a revocation signature from a valid
revocation key, but the revocation key is not present to verify the
signature.

* pkclist.c (check_signatures_trust): Use it here to give a warning when
showing key trust.

* compress-bz2.c: Include stdio.h.  Solaris 9 has a very old bzip2 library
and we can at least guarantee that it won't fail because of the lack of
stdio.h.

* tdbio.c: Fixed format string bugs related to the use of DB_NAME.
