Subject: Working support for multiple UARTs.

Default behavior (printf, gets, etc.) routes to DEFAULT_UART, set in hal_uart.h. Use fputstr() to print to other UARTs. Bring
fgets() from hal_io.c out in hal_io.h if you want to read data from other UARTs.

Still blocking. No interrupt-driven stuff yet.
