Fix the way mail accounts for the status of messages.

* mail/mail.h (MAIL_ATTRIBUTE_PRESERVED)
(MAIL_ATTRIBUTE_TOUCHED): New define.
* mail/from.c (mail_from0): Mark with 'R' only those messages that
have been read in this mail session.
* mail/hold.c (hold0): Set MAIL_ATTRIBUTE_PRESERVED
* mail/mbox.c (mbox0): Don't mark message as read.
* mail/quit.c (mail_mbox_commit): Force keepsave on
not system mailboxes.
* mail/touch.c: Use MAIL_ATTRIBUTE_TOUCHED
* mail/undelete.c: Clear MAIL_ATTRIBUTE_PRESERVED and
MAIL_ATTRIBUTE_MBOXED bits.
* mail/testsuite/mail/write.exp: Account for the above changes.
