	* mail-crypto.c (mail_crypto_is_smime_v3_signed): Removed (this
	now exists in camel/camel-smime.c).
	(mail_crypto_is_pkcs7_mime): Same.
	(mail_crypto_smime_part_sign): new
	(mail_crypto_smime_part_verify): new
	(mail_crypto_smime_part_encrypt): new
	(mail_crypto_smime_part_decrypt): new
	(mail_crypto_pgp_mime_part_sign): Added code to set an exception
	if the context fails to be created.
	(mail_crypto_pgp_mime_part_verify): And here...
	(mail_crypto_pgp_mime_part_encrypt): Same.
	(mail_crypto_pgp_mime_part_decrypt): And here too.
