resides above the last non-0xff data value in the address space. Only
do this for flash memory since writing a 0xff to flash is a no-op.
This has the affect of creating smaller output files when dumping
memory contents from flash if the program in flash does not consume
the whole memory space. It also results in shorter programming times
when avrdude is asked to load a file into flash that has lots of 0xff
filled data past the last non-0xff data value.
I think this is basically where Alexey was going with his s-record
routine, but this should have a similar affect for all the I/O
routines. The main difference is that Alexey's also optimized 0xff
from the beginning of the address space and was not limited to flash.
I think that these optimizations should be limited to the flash since
it is currently the only memory that treats 0xff as special.

all on non-paged-memory parts. The problem was that the page size was
defaulting to 256 (maximum for the stk500), but the timeout for a
response from the stk500 before declaring it dead was only 0.5
seconds. But it takes much longer than 0.5 seconds to program 256
bytes, so we just weren't waiting long enough.
Fix this in two ways - increase the timeout to 5 seconds, and decrease
the page size to 16 bytes for non-paged parts. The programming time
for 16 bytes is short enough to provide the user with some feedback
that something is happening.

This change represents a name change only. There is currently an
effort to port AVRPROG to other platforms including Linux and Windows.
Since Atmel's programmer binary that's included within their AVR
Studio software is named AVRPROG.EXE on the Windows OS, there is the
chance for confusion if we keep calling this program AVRPROG as well.
Up until now the name hasn't really been a problem since there was no
chance to confuse 'avrprog' on Unix with Atmel's AVRPROG because
Atmel's tools only run on Windows. But with the Unix 'avrprog'
possibly being ported to Windows, I felt a name change was the best
way to avoid problems.
So - from this point forward, my FreeBSD Unix program formerly known
as AVRPROG will subsequently be known as AVRDUDE (AVR Downloader/UploaDEr).
This change also represents a time when the AVRDUDE sources move from
my own private repository to a public repository. This will give
other developers a chance to port AVRDUDE to other platforms and
extend its functionality to support additional programming hardware,
etc.
So goodbye AVRPROG, welcome AVRDUDE!

Fix setting of status LEDs under various write-fail conditions.
Add a flag to indicate that a memory type requires the device to
possibly be powered off and back on after a write to it. This is due

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.

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.
