Bug fixes and new features



Many changes in this release, including:



- The new RawSerial class is a simple wrapper over the serial HAL that can

be safely used from an interrupt handler.

- Interrupt chaining code was removed from InterruptIn, Serial and Ticker

because it caused lots of issues with the RTOS. Interrupt chaining is

still possible using the InterruptManager class.

- InterruptIn has two new methods (enable and disable irq)
