Another case where we just search for : to separate host and port

---------------------------------------------------------------------- 
This problem is quite a bit deeper than the problem reported here. The
problem is that the use of SIP domains has had a big behavior change here.

Prior to the IPv6 merge, SIP domains were purely either host names or IP
addresses. Now, there are several cases in the code where domains are added
with a port appended to them. Examples include the auto_sip_domains section
in reload_config(). Another example is in most cases where the
refer_to_domain is set. In most of these cases, the port is not stripped
off at all before setting the value. This value is then used as an argument
for check_sip_domain(). In the case oej found, the port is attempted to be
stripped off, but the method is flawed when dealing with IPv6 addresses.
