* removed pp_l2_check (fixed L2 bug in mISDNuser)

* added blocking flag to stack object. A port can be blocked/unblocked from the
  cli
* added EVENT_PORT_ALARM to send alarm infos to the chan_misdn.c layer (later	
  we can add a manager event for that)
* added block_on_alarm option, to block the port whenever a ALARM occurs
* added need_busy flag to indicate if we've sended a CONTROL_BUSY already
* changed a bunch of cb_log(-1,..) to cb_log(0,..) due to funny behaviour in 
  recent asterisk ast_log messages..
* fixed a few ETSI state violations, especially when finishing calls in 
  different seldom states
* changed debug levels a lot to make the log more readable in low debuglevels
* some first fixes for the HOLD/RETRIEVE stuff (doesn't work totally still)
* removed the PRECONNECTED state stuff
* added cause 27 when we get a CLEANUP directly after a outgoing SETUP, this
  creates a CHANISUNAVAIL instead of a NOANSWER
* removed the addr pointer from "misdn show stacks" that's not needed anymore 
  and makes the output more unreadable
* added cause saving on RELEASE/RELEASE_COMPLETE
* set cause to 16 on prepare_bc
* removed stack getting from ph_control functions, we don't really need it 
  there
* added beroec api
