bsd efb9aaf8aa This is a jajor re-write of the programming algorithms. The Atmel
serial programming instructions are not very orthoganal, i.e., the
"read fuse bits" instruction on an ATMega103 is an entirely different
opcode and data format from the _same_ instruction for an ATMega163!
Thus, it becomes impossible to have a single instruction encoding
(varying the data) across the chip lines.

This set of changes allows and requires instruction encodings to be
defined on a per-part basis within the configuration file.  Hopefully
I've defined the encoding scheme in a general enough way so it is
useful in describing the instruction formats for yet-to-be invented
Atmel chips.  I've tried hard to make it match very closely with the
specification in Atmel's data sheets for their parts.  It's a little
more verbose than what I initially hoped for, but I've tried to keep
it as concise as I could, while still remaining reasonably flexible.

bsd 5abf255801 Fix (again, hopefully) page addressing for the ATMega parts.
Rename the poorly chosen name "bank" to "page" for page addressing.
Atmel calls it "page" in their documentation.

bsd 1426180b07 Try and detect an old-style config file and print an appropriate error
message and a suggestion for correcting it.

bsd f8677f8d4c Use lex/yacc for parsing the config file. Re-work the config file
format using a more human-readable format.

Read part descriptions from the config file now instead of hard-coding
them.

Update usage().

Cleanup unused code.
