update to gpgme-0.9.0

Noteworthy changes in version 0.9.0 (unreleased)
------------------------------------------------

 * The type gpgme_key_t has now a new field keylist_mode that contains
   the keylist mode that was active at the time the key was retrieved.

 * The type gpgme_decrypt_result_t has a new field "wrong_key_usage"
   that contains a flag indicating that the key should not have been
   used for encryption.

 * Verifying a signature of a revoked key gives the correct result now
   (GPG_ERR_CERT_REVOKED error code).

 * Clarified that the error code GPG_ERR_NO_DATA from the decrypt &
   verify operations still allows you to look at the signature
   verification result.

 * Clarified that patterns in keylisting operations have an upper
   limit, and thus are not suited to list many keys at once by their
   fingerprint.  Also improve the error message if the pattern is too
   long for the CMS protocol to handle.
