core: Add 'is_mime' flags to the verify and decrypt results.

* src/op-support.c (_gpgme_parse_plaintext): Add arg r_mime.
* src/decrypt.c (_gpgme_decrypt_status_handler): Ser mime flag.
* src/verify.c (_gpgme_verify_status_handler): Ditto.
* src/gpgme.h.in (gpgme_op_verify_result_t): Append fields 'is_mime'
and '_unused'.
(gpgme_op_decrypt_result_t): New field 'is_mime'.  Shrink '_unused'.

* tests/run-decrypt.c (print_result): Print MIME flag.
* tests/run-verify.c (print_result): Ditto.
--

Note that this flag (Liternal Data packet's 'm' mode) is only
specified in RFC-4880bis.  To use it you currently need to add
"rfc4880bis" to the the gpg.conf.
