  Deadlock between dahdi_request() and pri_dchannel() processing an incomming call.
  
  The sig_pri_new_ast_channel() is called with the channel private lock held
  when pri_dchannel() calls it and no channel private lock held when
  dahdi_request() calls it.  The use of pri_grab() in
  sig_pri_new_ast_channel() could leave the channel private lock held when
  it returns if the lock was not held before calling it.
  
  Make sig_pri_new_ast_channel() just lock the PRI span lock instead of
  using pri_grab().  It is safe to do this because dahdi_request() does not
  have the channel private lock and the deadlock potential with the PRI span
  lock is only between pri_dchannel() and other threads.
