  Fix the ability to specify an OSP token for an outbound IAX2 call.
  
  When this patch was originally submitted, the code allowed for the token to be
  set via a channel variable.  I decided that a cleaner approach would be to
  integrate it into the CHANNEL() function.  Unfortunately, that is not a suitable
  approach.  It's not possible to get the value set on the channel soon enough
  using that method.  So, go back to the simple channel variable method.
