	PR 349/bsps
	* console/console.c, console/uart.c, console/uart.h: implement
	IOCTLs for the serial (UART) console to install/retrieve a BREAK-IRQ
	callback.  The callback routine (if installed) is invoked from the
	UART ISR when a BREAK interrupt is detected.  This can be used
	e.g. to enforce a "hotkey" reboot a la vxWorks Ctrl-X (although we
	use the serial line break condition) NOTE: The callback runs in
	ISR context.
