	* gpgme.h: Add prototype for gpgme_get_key.
	* key.c (gpgme_get_key): New function.
	* verify.c (gpgme_get_sig_key): Rewrite using gpgme_get_key.

	* gpgme.h: Add prototypes for new interfaces
	gpgme_key_sig_get_string_attr and gpgme_key_get_ulong_attr.
	(enum GpgmeAttr): New attribute GPGME_ATTR_SIG_CLASS.
	* gpgme.c (gpgme_set_keylist_mode): Allow GPGME_KEYLIST_MODE_SIGS.
	* key.h (struct certsig_s): New members ALGO, NAME_PART,
	EMAIL_PART, COMMENT_PART, NAME, SIG_STAT and SIG_CLASS.

	* conversion.c (_gpgme_decode_c_string): Add new parameter LEN.
	Use that to determine if allocation is desired or not.
	* util.h: Adjust prototype of _gpgme_decode_c_string.
	* keylist.c (keylist_colon_handler): Adjust caller of
	_gpgme_decode_c_string.

	* key.h (struct gpgme_key_s): New member last_uid.
	* key.c (_gpgme_key_append_name): Rewritten using
	_gpgme_decode_c_string and the last_uid pointer.
	(my_isdigit): Macro removed.
	(ALLOC_CHUNK): Likewise.
	* keylist.c (set_userid_flags): Use last_uid member of KEY.

	* context.h (struct user_id_s): New member last_certsig.
	* key.h: Add prototype for _gpgme_key_add_certsig.
	* key.c (_gpgme_key_add_certsig): New function.
	(set_user_id_part): Move function before _gpgme_key_add_certsig.
	(parse_user_id): Change first argument to SRC, add new arguments
	NAME, EMAIL and COMMENT.  Change code to use these arguments
	instead going through UID.  Move function before
	_gpgme_add_certsig.
	(parse_x509_user_id): Likewise.
	(_gpgme_key_append_name): Adjust arguments to parse_x509_user_id
	and parse_user_id invocation.
	(one_certsig_as_xml): New function.
	(one_uid_as_xml): Print signatures.
	* context.h (struct gpgme_context_s): New member TMP_UID.
	* keylist.c (keylist_colon_handler): Rewritten, implement "sig"
	record entries.

	* key.c (get_certsig): New function.
	(gpgme_key_sig_get_string_attr): Likewise.
	(gpgme_key_sig_get_ulong_attr): Likewise.

	* keylist.c: Include <ctype.h>.
	(my_isdigit): Macro removed.
	(set_mainkey_trust_info): Use isdigit, not my_isdigit.
	(set_userid_flags): Likewise.
	(set_subkey_trust_info): Likewise.
	(set_ownertrust): Likewise.
	(finish_key): Move function up a bit and remove prototype.

	* rungpg.c (gpg_keylist_ext): Correct precedence of signature
	listing mode.
	(gpg_keylist_ext): Implement signature listing mode.
