Add support for ATMega163.

Browse Source 
Add support for reading/writing ATMega163 lock and fuse bits.
Unfortunately, in looking at the specs for other ATMega parts, they
use entirely different instruction formats for these commands.  Thus,
these routines won't work for the ATMega103, for example.

Add support for sending raw command bytes via the interactive terminal
interface.  This allows one to execute any programming instruction on
the target device, whether or not avrprog supports it explicitly or
not.  Thus, one can use this feature to program fuse / lock bits, or
access any other feature of a current or future device that avrprog
does not know how to do.

Add in comments, an experimental instruction format in the
configuration file.  If this works out, it would allow supporting new
parts and non-orthoganal instructions across existing parts without
making avrprog code changes.
