joerg_wunsch b991041fe3 * butterfly.c (butterfly_initialize): when sending the 'T'
command (which is ignored by current AVR109 bootloaders),
send the first reply from the list of supported device
codes back rather than using avrdude.conf's idea about
an AVR910 device code.  Apparently, this solves disagreements
between different versions of at least the ATmega8 AVR910
device code.

Closes bug #18727: Writing flash failed

joerg_wunsch 31fa98b708 Make the code compile warning-free:
- declare a dummy "struct timezone" for some Win32 systems (MinGW)
- fix a few printf() argument types
- get rid off the prevailing "all filedescriptors are of type int"
  attitude

The last item required a large sweep across the code, in order to
replace all "int fd"s by "struct filedescriptor *fd"s, and pass
pointers (as we cannot pass a union directly).  In return, the
code is now supposed to be fully 64-bit safe, rather than relying
on a 64-bit pointer being converted to a (32-bit) int and back
to a pointer as we did previously.

joerg_wunsch 351f329ec8 Replace the fallback of avr_read_byte() and avr_write_byte() to
avr_read_byte_default() and avr_write_byte_default (resp.) by directly
calling the latter functions from within all programmers that don't
implement their own read_byte()/write_byte() methods.  In turn, make the
read_byte() and write_byte() methods mandatory, and the cmd() method
(direct ISP command) optional instead (it's effectively mandatory for
any programmer using avr_read_byte_default()/avr_write_byte_default()
though).  Remove all the pointless cmd() method stubs from those programmers
that don't need it.

Eliminate avr_read_byte() as it was now completely identical to
pgm->read_byte().

joerg_wunsch 83b162593f * butterfly.c: Remove the device support decision based on
the old AVR910 device codes; we've got signature verification
now so better rely on that.

* avr910.c: Revert the signature bytes returned, as it already
happened in butterfly.c.  This closes bug #14998: Signature Bytes
read in wrong order (avr910 mode)

it is beyond 0x80.

to synchronize with the device.

bdean 20f3be439c Eliminate compiler warnings. GCC 4.x elicits many signedness warnings
when passing unsigned char * when char * is in the prototype and vice
versa.  Clean these up along with a few others.

joerg_wunsch eed121e91f Extend the butterfly code to fully support AVR109 boot loaders. Notable
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.

joerg_wunsch d2825e00fd Revert the serial_recv() timeout handling as it used to be before my
yesterday's changes (i.e. before rev. 1.10 of ser_posix.c), that is,
exit(1) in case of a timeout.  Previously, the upper layers didn't see
the timeout at all.

Quite possible that some of these drivers could handle a timeout more
intelligently though.  At least for the rather sophisticated STK500v2
protocol, I think it should be possible to retry the request.
