Eliminate the old JSON parser, implemented in osrf_json_parser.c and

Eliminate the old JSON parser, implemented in osrf_json_parser.c and
the associated header osrf_json_utils.h.

This parser has been completely replaced by a newer one implemented
in osrf_parse_json.c, plus an incremental JSON parser (so far
unused) in jsonpush.c..

The even older parser of JSON-with-comments is not affected.
