DrZiplok@gmail.com 22c9ed317e Change the way that FastSerial ports are created, so that we can avoid 
creating port drivers for ports that aren't used.

This lets us save the RAM (~200 bytes per port) that would otherwise
have been used for buffers.  It also frees up the port's interrupt
vectors so that on Mega we can use the ports for other things
(e.g. SPI Master mode).

Better to fix this now than later when we have more consumers.

DrZiplok@gmail.com b4a840a336 Add 'extern' definitions to legitimise clients that want to assume that Serial* always exists.

DrZiplok@gmail.com 6074c410d9 "Fast" serial driver that fully overrides the Arduino-provided HardwareSerial/Serial* driver. 
The receive side is basically a copy of the HardwareSerial driver, whilst the transmit side
uses the same algorithm as the APM_FastSerial driver.

See the example sketch for usage details.
