Bugfixes.

* libproto/mailer/smtp.c (_smtp_set_rcpt): Assign rcpt_to a copy of the
recipient address.
* mail/util.c (util_header_expand): Make sure exp is always initialized.
* mh/send.c (main): Process mtstailor before checking input files, so
its settings affect creation of additional headers and adresses. In
particular, this allows for setting the sender address in mtstailor.
