ZOOM_query_cql2rpn translates the CQL string, client-side, into RPN which may be passed to the server. This is useful for servers that don't themselves support CQL, for which ZOOM_query_cql is useless. 'conn' is used only as a place to stash diagnostics if compilation fails; if this information is not needed, a null pointer may be used. The CQL conversion is driven by option cqlfile from connection conn. This specifies a conversion file (e.g. pqf.properties) which must be present.

ZOOM_query_ccl2rpn translates the CCL string, client-side, into RPN which may be passed to the server. The conversion is driven by the specification given by config. Upon completion 0 is returned on success; -1 is returned on failure. On failure error_string and error_pos hold the error message and position of first error in original CCL string.
