Summary:                    [patch] SIP over TCP project
Description: 
I added TCP support to asterisk SIP channel. I put all my changes under
#ifdef SIP_TCP_SUPPORT and left the original code. So if you search
SIP_TCP_SUPPORT, you can find my changes very easily.

My changes
-Added TCP listening socket, siptcpsock.
-Added securechannel, sockfd, transport field to struct sip_pvt.
-Added transport, tcpsockfd field to struct sip_peer.
-Added TCP read in sipsock_read().
-Added siptcp_accept() to accept an incoming TCP connection request.
-Added transport, q parameter processing in Contact header parsing.
-Changed the hard-coded "UDP" in Via header to copy sip_pvt.transport.
-Added tcp_conenct() to make a TCP connection for outgoing message.
-Added TCP transmit in __sip_xmit().
-Saved TCP connecton socket to sip_peer.tcpsockfd, copied it to
sip_pvt.sockfd when OPTIONS or INVITE is sent to the peer that is using
TCP.

I tested it mainly xlite(UDP only free version) and Jain-SIP communicator.
call signal is working well. One problem I am having is Jain-SIP
communicator doesn't receive any audio, I don't know why. If any one has
xlite-pro(TCP supported commercial version) or TCP supported SIP clients, I
am looking forward to hear the test result.

Welcome any comment.
Thanks

alphaque: Can you provide a patch against current svn trunk ?
As serge-v stated several times this is a new feature and should be
developed for trunk, not a release (1.2 or 1.4)
