MULTIPART_MIXED_SEEN.
(decrypt_data): Add --no-options.
(verify_signature): Ditto.
(new_part): Check for Wks-Draft-Version header.  Take care of text
parts.
(wks_receive): Set Parser and pass a flag value to RESULT_CB.
* tools/gpg-wks-client.c (read_confirmation_request): New.
(main) <aRead>: Call read_confirmation_request instead of
process_confirmation_request.
(command_receive_cb): Ditto.  Add arg FLAGS..
(decrypt_stream_status_cb, decrypt_stream): New.
(command_send): Set header Wks-Draft-Version.

DRAFT_VERSION_2.
(sign_stream_status_cb, sign_stream): New.
(command_receive_cb): Set draft flag.
(send_confirmation_request): Rework to implement protocol draft
version 2.

* tools/gpg-wks.h (DBG_MIME_VALUE, DBG_PARSER_VALUE): New.
(DBG_MIME, DBG_PARSER, DBG_CRYPTO): New.  Use instead of a plain
opt.debug where useful.
* tools/gpg-wks-client.c (debug_flags): Add "mime" and "parser".
* tools/gpg-wks-server.c (debug_flags): Ditto.

If a client supporting the version 2 of the protocol is used, it will
tell this the server using a mail header.  An old server will ignore
that but a recent server will use the new protocol.  Next task is to
actually write draft-02.

There are still a lot of FIXMEs - take care.
