    Fix memory leak if chan_misdn config parameter is repeated.
    
    Memory leak when the same config option is set more than once in an
    misdn.conf section.  Why must this be considered?  Templates!  Defining a
    template with default port options and later adding to or overriding some
    of them.
    
    Patches:
          memleak-misdn.patch
