  Fix parsing error in sip_sipredirect().
  
  The code was written in a way that did a bad job of
  parsing the port out of a URI. Specifically, it would
  do badly when dealing with an IPv6 address. In this
  particular scenario, there was no value from parsing
  the port out, so I just removed that logic. And while
  I was messing around in the function, I changed some
  variable names to be more descriptive.
