Fix mime creation and Sieve reject/redirect actions.

* examples/mta.c (finalize_option): New variable.
(message_finalize): Don't modify the message if finalize_option
is 0.
* include/mailutils/sys/message.h (_mu_message)
<orig_header_size>: New member.
* include/mailutils/sys/mime.h (_mu_mime) <part_stream>: New member.
* libmu_sieve/actions.c (mime_create_reason)
(mime_create_ds): Use mu_body_get_streamref.
(mime_create_quote): Use mu_body_get_streamref/mu_message_get_streamref.
(sieve_action_reject): Set the To: header.
* mailbox/message.c (mu_message_get_header): Set orig_header_size.
(mu_message_get_body): Use orig_header_size instead of relying
on mu_header_size.
* mailbox/mime.c (_mime_part_size): New static.
(_mime_body_stream_size): New method.
(_mime_body_seek): Rename to _mime_body_stream_seek.
(_mime_body_read): Rewrite and rename to _mime_body_stream_read.
(_mime_body_ioctl): Rename to _mime_body_stream_ioctl.
(create_mime_body_stream): Take mu_mime_t as the 2nd parameter.
Initialize sp->stream.size and sp->mime.
(_mime_body_size): Rewrite using _mime_part_size.
(mu_mime_destroy): Destroy part_stream.
* sieve/testsuite/Redirect: Reflect new mta behavior.
* sieve/testsuite/Reject: Likewise.
