Bug description:wrong use efree(NULL) in intl

Description:
------------
intl_convert_utf8_to_utf16() is wrong used in a multiple points. Example

165	    intl_convert_utf8_to_utf16(&uhaystack, &uhaystack_len, (char *)
haystack, haystack_len, &status );
166
167	    if ( U_FAILURE( status ) ) {
168	        /* Set global error code. */
169	        intl_error_set_code( NULL, status TSRMLS_CC );
170
171	        /* Set error messages. */
172	        intl_error_set_custom_msg( NULL, "Error converting input
string to UTF-16", 0 TSRMLS_CC );
173	        efree( uhaystack );
174	        return -1;
175	    }

efree() call to uhaystack => (efree(NULL)). sometime 'uhaystack' may be
NULL. It's a multiple problem in intl. Then efree() print error
