* main.h, keygen.c (keygen_add_revkey): Add revocation key subpackets to a

Browse source 
signature (callable by make_keysig_packet). (write_direct_sig): Write a 1F
direct key signature. (parse_revocation_key): Parse a string in
algo:fpr:sensitive format into a revocation key. (get_parameter_revkey,
do_generate_keypair): Call above functions when prompted from a batch key
generation file.

* build-packet.c (build_sig_subpkt): Allow multiple revocation key
subpackets in a single sig.

* keydb.h, getkey.c (get_seckey_byfprint): Same as get_pubkey_byfprint,
except for secret keys.  We only know the fingerprint of a revocation key,
so this is needed to retrieve the secret key needed to issue a revokation.

* packet.h, parse-packet.c (parse_signature, parse_revkeys): Split revkey
parsing off into a new function that can be used to reparse after
manipulating the revkey list.

* sign.c (make_keysig_packet): Ability to make 1F direct key signatures.
