This PR allows kamailio to duplicate messages to Homer using HEPv3 [0]. An optional correlation ID (which can contain PVs) can be passed to `sip_trace()`.

The packing macros in hep.h are authored by @camilleoudot and I've just used them.

An example of formats:

``` modparam("siptrace", "duplicate_uri", "sip:127.0.0.1:9062") ... sip_trace("sip:127.0.0.1:9060", "123"); // duplicate URI + correlation ID sip_trace("", "345"); // default URI + correlation ID sip_trace("", "$fU-678"); // default URI + correlation ID with PVs sip_trace(); // default URI + no correlation ID ```
