    sys/netinet          udp_usrreq.c 
  In in_pcbconnect_setup() jailed sockets are treated specially: if local
  address is not supplied, then jail IP is choosed and in_pcbbind() is called.
  Since udp_output() does not save local addr after call to in_pcbconnect_setup(),
  in_pcbbind() is called for each packet, and this is incorrect.
  So, we shall treat jailed sockets specially in udp_output(), we will save
  their local address.
  This fixes a long standing bug with broken sendto() system call in jails.
