  SIP support for keep-alive event

  keep-alive events are used by Sipura/Linksys for NAT keepalive.
  There currently don't appear to be any problems with NAT, but
  everytime a keep-alive event is received, Asterisk responds with a
  "489 Bad event".  This error may indicate to a user that NAT
  problems exist just because this even is not supported.  Now,
  rather than respond with an error, the packet is consumed and
  a "200 ok" is sent just to indicate we received the packet.

  (issue #15084)
