Some Sort of SIGINT

You do not have always a reset button to restart a hanging console, power cycle is not convenient in most cases. There is now an assert for ^C, UART errors (FIFO, interruption) throw an assert too.

If you want something similar to an SIGINT, replace the assert ASSERT_nonfatal() with osThreadFlagsSet() or osEventFlagsSet() to inform your application thread. uart.c
