* add support for parts with just 'fuse' memory
* if any fuse memories are altered, reflect those changes in the
post-programming safemode check so that safemode no longer
complains about fuses which were intentionally altered; this
eliminates the need to completely disable safemode using -u in
order to program fuses.
* provide -s option which will not ask to restore fuses, it will
just do it

His addition has been implemented by means of a generalized bit-bang
interface that contains the common part between serial and paralle
bit-bang devices, and specialed backends for the serial and parallel
port connections.

avr910 programmer.
Original Submission: The attached patch against avrdude 4.4.0 fixes
the following problems with paged writes in avr910.c:
- failure to re-set address after page writes;
- no polling or delay after page writes;
- no page writes when not using auto-increment;
- an extraneous page write when data ends on page boundary.

Do not rebuild the docs again if they are up-to-date. This avoids as
well that they are rebuilt during "make install".
Use mv -f instead of plain mv in order to install the docs into the
respective subdirs, in order to avoid silly questions for non-writable
destination files.

This fixes EEPROM access using the STK500V2 programmer, partially
undoing part of a previous general fixup commit. Choose the correct
read/write operations with the stk500v2 program function - the correct
one depends on the memory type. EEPROM is byte addressable so uses
read/write. FLASH is word addressable and so uses read_lo/write_lo.

to 'i' (input). Even though this bit should be ignored, it should not
be changed. The 'x' setting sets the bit to zero which programs it
and could cause undefined behaviour. Setting to 'i' enables it to be
rewritten to its old value.
A better solution might be to read the fuse byte, apply the new value
while leaving the 'x' bit alone, then writing the value back. The
current fix is a workaround which allows the developer to change the
bit.

#13693, #13871, and #14212.
This provides bug fixes to the STK500V2 programmer type. From the
patch information:
- incorrect token used from avrdude.conf.in
- wrong command sent to programmer, hence no write to eeprom.
- programmer was said to start writing at 0x0000 and continue page
by page and was not repositionned when a gap was found in the
hex file, or when the hex file start address was not
0x0000. Hence the verify procedure was correct, not the write
procedure.
- speed up of flash write to skip empty pages (full of 0xFF) by
re-enabling a dedicated function for that task.
- stk500v2_paged_load() was not returning the number of byte read,
so empty hex files were generated when reading memory.

changes to butterfly.c include:
. do not exit for unsupported devices but return -1 from the init function
instead; that way the -F option can be used to continue anyway
. honor the -b option as arbitrary bootloaders could be implemented with
any baud rate, not just the fixed 19200 Bd used by the butterfly
. implement functionality to read the fuse and lock bits, and write the
(boot) lock bits, resp.
. fix the signature byte order
The remaining files document the new functionality.

mkII.
The serial transport methods have been moved out into a record of
function pointers for that purpose, defaulting to the actual serial
connection that natively applies to the hosting system. Iff inside
the JTAG ICE mkII handler a port name starting with "usb" has been
detected, the record of function pointers is switched to USB.
Optionally, a serial number might be specified, so only the JTAG ICE
mkII matching the given serial number will be opened. The match is
done right-to-left, so only the least significant bytes of the serial
number need to be given.
In order to make the change as least intrusive to existing drivers as
possible, the entire naming scheme of the serial_foo() function entry
points has been maintained as access macros that encapsulate these
into the respective indirect function calls via serdev->foo().

number.
When discarding a packet for being overly long, restart the state
machine instead of attempting to drop a preposterous amount of data.
It is unlikely in that case that preposterous amount of data would
ever arrive, so rather attempt to re-align the reading algorithm
(supposedly resulting in a timeout and retransmit).
