[Users] NEW FEATURE: support for multiple RTPproxies

[Bogdan-Andrei Iancu]

Hi,

thanks to Ancuta Onofrei, a new member of Voice System's team, NATHELPER 
module now supports multiple rtpproxies - actually you can define 
multiple sets of rtpproxies - nathelper performs load-balancing over a 
set and the user can select the set.

For more details, see:
    http://www.openser.org/docs/modules/devel/nathelper.html#AEN76


The definition of the rtpproxy socket was extended to allow definition 
of multiple sets. See:
    http://www.openser.org/docs/modules/devel/nathelper.html#AEN140

Also, a new function was added to set from script what set of rtpproxies 
is to be used. See:
    http://www.openser.org/docs/modules/devel/nathelper.html#AEN298


Example:

# multiple sets of multiple rtproxies
modparam("nathelper", "rtpproxy_sock", "1 == udp:localhost:12221 udp:localhost:12222")
modparam("nathelper", "rtpproxy_sock", "2 == udp:localhost:12225")

.....
set_rtp_proxy_set("2");
force_rtp_proxy();
.....
