[2.0.x] Arduino Due XON/XOFF implementation

Alos includes emergency parser and configurable TX/RX buffers for Arduino Due.

This is the ONLY way to be able to override ISRs stolen by the Arduino Runtime, such as Serial or USB device interrupts. This feature is needed so Arduino modules can be replaced and enhanced.

Instead of using const char, it is better to use uint8_t

Although this is an external contribution, clean up anyway to stop seeing it in global searches for typical flaws.
