order to minimize the number of interrupts generated, it is possible to
disable the feature and return to the old code which is a bit smaller, see
the configuration parameters in ./ARM7-LPC214x/GCC/lpc214x_serial.h.
- Some more work done on the AVR port, not tested yet.
- Some more work done on the AVR port, it is almost complete but not tested
yet because my JTAG probe broke...
*** 0.3.4 ***
- Fixed a problem in chVTSetI().
