Summary: B2B_LOGIC: completely lumps support

Initial Comment:
Now you can change all parts of message before b2b_init_request call and in b2b_request/b2b_reply routes.

It useful for add additional headers before b2b_init_request to pass through b2b (don't forget custom_headers param) and also for NAT processing in b2b_request/b2b_reply routes.

Instead of patch #3515749. Please, ignore/remove old patch.

Message:
The way we use this patch in our production environment to process NAT via
b2b:

route {
        force_rport();

        # Here are some checks, deny non-invite requests.

        # Fix NATed contact and SDP in client requests
        if (nat_uac_test("19")) fix_nated_contact();
        if ( (has_body("application/sdp")) && (nat_uac_test("8")) )
fix_nated_sdp("10");

        b2b_init_request("top hiding");
        exit;
}

route[B2B_REQUEST] {
        force_rport();

        # Fix NATed contact and SDP in client requests
        if (nat_uac_test("19")) fix_nated_contact();
        if ( (has_body("application/sdp")) && (nat_uac_test("8")) )
fix_nated_sdp("10");
        
        # Also we can add this our custom headers
}

route[B2B_REPLY] {
        # Here we can also add our custom headers
}

onreply_route {
        # Fix NATed contact and SDP in client replies
        if (nat_uac_test("97")) fix_nated_contact();
        if ( (has_body("application/sdp")) && (nat_uac_test("8")) )
fix_nated_sdp("10");
}

Message:
Added v4 patch.
Fixed:
- b2b_request_route called before tm transaction created. Now we can use
force_rport() and change contact header in b2b_request_route. We use it to
process NAT on b2b.
