[reSIProcate] Using SipMessage::addOutboundDecorator from within a DUM application

[Scott Godin]

Be careful about threading - make sure you are not modifying the profile in
one thread, when dum might be using it another.

You could create a profile just for that one Invite session - however it
will be called for all messaging within the InviteSession.  The decorator
itself can be smart enough to only act on the initial INVITE (ie. no To
tag).
