    chan_misdn: Timer primitives must be handled first.
  
    The frm->addr is a different "address space" than the stack/instance
    address of other Lx primitives.  The test for B channel instance address
    could fail.

    chan_misdn: Free memory in error paths and other memory leaks.
  
    The one line commented with BUG is not easily fixable because there is no
    de-init function one can call.

    chan_misdn: ISDN NT L2 de-establish/establish
  
    * An NT-PTMP cannot de/establish L2 since it doesn't know the TEIs.
    * On NT-PTP L2 is started when L1 is finally active in handle_l1.
    * L2 deactivation logging cleanup.
    * L2 aggregate link status is unknown for NT-PTMP, show as "UNKN".
    * Removed unused functions and code for L2 handling.

    chan_misdn: Fix broken upper_id/lower_id usage.
  
    Sending PH prim via lower_id layer (3 or 1) simply does not work.  For TE
    (3) it returns an error (len=-6) which is not evaluated by handle_l1(), so
    the L1 layer status ends up wrong.  Instead PH must be sent via L4, only
    then does it reach L1 without an error message.
  
    And NT PH prims only reach L1 when they are sent to layer 2 id.
    --> use upper_id to send PH primitives.
  
    * Check for errors in PH_(DE)ACTIVATE | CONFIRM.
    * Debug messages are improved.
  
    * The lower_id is now not used for anything, except: Why is lower_id layer
    deleted when it wasn't created?  I removed this code since it looks very
    wrong.

    chan_misdn: Fix loss of B channels if L1 is down.
  
    If you make 2 calls out an NT PTMP port which is not connected to any
    phone, the B channel associated with that call becomes unusable until
    Asterisk is restarted.
  
    The problem is the EVENT_SETUP is queued when L1 is not up in
    misdn_lib_send_event().  If L1 cannot be activated the event won't be
    dequeued.  It gets even worse when the call is hung up.  The queued
    EVENT_SETUP will be overwritten by an EVENT_DISCONNECT.  The reserved B
    channel then will never be freed.  If later someone connects a phone to
    the port, L1 will eventually activate and the queued EVENT_DISCONNECT is
    sent down the stack.  However, it is ignored because it is the wrong call
    state.
  
    The real fix would be that activation and queueing for a new SETUP is done
    by the NT stack.  But since it doesn't, the workaround must be removed
    because it doesn't always work.
  
    Fix: The event is no longer queued but immediately sent to the stack.  If
    L1 cannot be activated, the L3 state machine that was started by the
    EVENT_SETUP will do its work, i.e.  a timeout will release the B channel
    properly.  The SETUP possibly cannot be sent the first time but is resent
    by T303 in case L1 could be activated.

    chan_misdn: Remove some calls to exit().
  
    Try proper cleanup when something goes wrong in misdn_lib_init().
    Especially do not call exit()!
  
    * Fix memory leak because stack_destroy() does not free the stack struct.
