Consolidate emergency debug output
This removes the duplicate uart_emergency_printf() vs. panic_printf()
/ uart_emergency_puts() vs. panic_puts() implementation and saves
~0.5kb of code size.
The other significant change is that uart_flush_output() is now smart
enough to determine if it's in an interrupt; if so, it will spin-flush
the output buffer instead of waiting on the uart interrupt. This
removes the need for a separate panic_flush().
