[OpenSER-Devel] New mediaproxy module

[Dan Pascu]

I will come back the next days with some more details about mediaproxy 
2.0, for them moment I will only highlight some of the most important 
changes:

- New design based on linux kernel connection tracking which is much more 
scalable and can fill up a network interface using very little resources.
- New interface based on the dialog module that allows one to trigger the 
use of mediaproxy on the first INVITE, after which all messages that 
belong to the session and have an SDP body will be automatically modified 
without a need to call any function anymore in the script. When the 
dialog ends the media session is also closed automatically without the 
need to call end_media_session()
- Encrypted communication between the dispatcher and the relays.
- T.38 fax support.
- Handle SDP with a mix of supported and unsupported streams.
- Be able to change the IP/port of caller/caller after a re-INVITE or 
UPDATE request in mid-dialog.
- No longer use a single port for relaying a stream, which makes detecting 
the caller/callee deterministic.
- Graceful shutdown capability for the media relay
- Removed support for asymmetric clients
- Improved and made accounting modular
- Discontinued support for DNS based specification of the relay addresses
- Discontinued support for per domain specification of the relays. One can 
still chose to use a certain relay, using $avp(s:media_relay)

In addition I fixed all bugs and shortcomings of the old design that were 
reported or I was aware of. If something is still not fixed or not 
working properly please report back.
