    _______________________________________________________

Details:

If there is a subclass of AVRDevice which has not filled in all I/O
registers, any access to an invalid register may cause a segfault.

Segfaults do not give much information and should generally be avoided, so
this patch makes simulavr handle all access to not-implemented I/O as invalid
I/O and makes it therefore more robust.
