* rework reference counting in the client libraries: now refcounting goes

Browse source 
strictly "one-way" - the "bigger" object refcounts the "smaller" one, never the
  other way round. 

* when registering for a reply packet in pdispatch, specify a function that is
  called when the pdispatch object is destroyed but the reply hasn't yet been
  recieved.

* move prototype of pa_free_cb from stream.h to def.h
