    Use interrupts to capture Serial UART data, not polling (#393) · dc1198bd
    Earle F. Philhower, III authored 
    PR #379 was an ugly hack which works only if you poll the Serial port more
frequently than ~8 byte times.

This PR replaces the polling with an IRQ based lockless writer/reader queue
so that even if you only read every 32 byte times, the Serial1/2 port should
not lose data.  It also should use less CPU and allow for somewhat higher
throughput.
