  usrloc/nathelper: Compute and report ping latencies

This patch adds a new nathelper branch flag, "sipping_latency_flag", to
enable ping latency computation. Also, a new usrloc event is now available,
E_UL_LATENCY_UPDATE. All contact-related usrloc events now include a new
parameter, "latency", which holds the latency of the last successful
ping if any, or 0 otherwise. If available, the ping latency can also be
accessed via MI, using the "Ping-Latency" key of the contact data.
