* Make asf streaming work again. Now uses the output format asf_stream.

Browse Source 
* Add ip address based acls for streams. I recommend adding ACL entries
  for all feeds to control who can submit stuff. You might also want to
  consider who can get to your status page.
* Make logging work again if customlog == "-"
