  -----------
  dialog PRACK: Fix issues during early-dialog

* work around the fact that r_cseq, Contact, and route-set and not yet
  present in the dst_leg struct.  So the use of send_leg_msg() and
  build_dialog_info() should be avoided here.
* fix outbound ACK CSeq to match the INVITE, rather than +1 due to
  the in-between PRACK
