   #  Do an ssi with retries:
   #  While I'd love to factor out this with the vesrion in lonprintout,
   #  that would either require a data coupling between modules, which I refuse to perpetuate
   #  (there's quite enough of that already), or would require the invention of another infrastructure
   #  I'm not quite ready to invent (e.g. an ssi_with_retry object).
   #
   # At least the logic that drives this has been pulled out into loncommon.
   
   
   #
   #   ssi_with_retries - Does the server side include of a resource.
   #                      if the ssi call returns an error we'll retry it up to
   #                      the number of times requested by the caller.
   #                      If we still have a proble, no text is appended to the
   #                      output and we set some global variables.
   #                      to indicate to the caller an SSI error occured.  
   #                      All of this is supposed to deal with the issues described
   #                      in LonCAPA BZ 5631 see:
   #                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
   #                      by informing the user that this happened.
   #
   # Parameters:
   #   resource   - The resource to include.  This is passed directly, without
   #                interpretation to lonnet::ssi.
   #   form       - The form hash parameters that guide the interpretation of the resource
   #                
   #   retries    - Number of retries allowed before giving up completely.
   # Returns:
   #   On success, returns the rendered resource identified by the resource parameter.
   # Side Effects:
   #   The following global variables can be set:
   #    ssi_error                - If an unrecoverable error occured this becomes true.
   #                               It is up to the caller to initialize this to false
   #                               if desired.
   #    ssi_last_error_resource  - If an unrecoverable error occured, this is the value
   #                               of the resource that could not be rendered by the ssi
   #                               call.
   #    ssi_last_error           - The error string fetched from the ssi response
   #                               in the event of an error.
