Merge 975c65c33f into c859b25da0

changes to the function:
static cJSON_bool print_value(const cJSON * const item, printbuffer * const output_buffer)

The function: strcpy((char*)output, "false") causes memory crashes in ThreadX(at least in my case). The modification delivers the same results, but without the crash.
