jim hamblen / Mbed 2 deprecated app-board-RTOS-Threads

This demo uses the mbed RTOS to run eight threads (including main). The threads are using different I/O devices on the application board. Several of the threads output to the LCD and an OS mutex lock is used to control access to the LCD and make the LCD thread safe.
