  Make generate_exchange_uuid() always return the passed ast_str pointer.
  
  I changed this code earlier to return NULL if it wasn't able to generate a UUID,
  whereas the earlier code would always return the ast_str that was passed in.
  Switch back to returning the ast_str, only set it to the empty string instead if
  UUID generation fails.  We still do a validity check later which will catch this
  and blow up if necessary.

  confbridge: Fix MOH on simultaneous user entry to a new conference.
  
  When two users entered a new conference simultaneously, one of the callers
  hears MOH.  This happened if two unmarked users entered simultaneously and
  also if a waitmarked and a marked user entered simultaneously.
  
  * Created a confbridge internal MOH API to eliminate the inlined MOH
  handling code.  Note that the conference mixing bridge needs to be locked
  when actually starting/stopping MOH because there is a small window
  between the conference join unsuspend MOH and actually joining the mixing
  bridge.
  
  * Created the concept of suspended MOH so it can be interrupted while
  conference join announcements to the user and DTMF features can operate.
  
  * Suspend any MOH until the user is about to actually join the mixing
  bridge of the conference.  This way any pre-join file playback does not
  need to worry about MOH.
  
  * Made post-join actions only play deferred entry announcement files.
  Changing the user/conference state during that time is not protected or
  controlled by the state machine.
