  * nta.c: setting the local sequence number of nta_leg_t only when first reques
t is sent.

  Application can now set the initial value of CSeq either in nta_leg_create()
  or in nta_outgoing_*create() (or nta_msg_request_complete()).

  * nua_session.c: fixed session timer negotiation when UAS does refreshing with
 INVITEs

  The session-expires header had "uac" even when uac did not support timer.
  The UAS failed to send re-INVITEs.

  Thanks for Chung Pak Lai for reporting this problem.

  * bnf: added host_cmp().

  * outbound.c: using host_cmp() to check if Via host and received parameter dif
fer

  Bug reported by Marc Blanchet.

  * nua_session.c: fixed leak in incomin INVITE processing.
