/* NAME: addfixdata
*
* DESCRIPTION: Filter fixdata stanzas.  
*
* PRECONDITIONS: fixdataDB exists (may be empty, but must be
*		 present).  This is to ensure we update what we
*		 intend to update. The format of fixdata stanza is:
*
*                fix:
*	               name = IX12345
*	               abstract = Apar abstract text
*	               type = f
*	               filesets = "foo.bar.fileset 04.01.0001.0003\n\
*                              foo.bar.second_fileset 04.01.0002.0001\n\
*                              "
*	               symptom = "Some symptom string which can be arbitrarily\n\
*                              short or long or absent.\n\
*                              "
*
* POSTCONDITIONS: output: writes stanzas that do not already exist in the
*		  database to stdout.
*
* INPUT PARAMETERS: stdin is fixdata stanzas
*	            argv[1] is the name of the database file
*
*                   The input is the output of buildfixdata
*	            (a set of fix database stanzas such as:)
*
* DATA STRUCTURES: None
*
* RETURNS:

* RETURNS: Returns 0 if a fixdata stanza was not found in the database file
