reported in the response packet, rather than full 512 byte which
are always reported by the CMSIS-DAP layer. Miscalculations

* usbasp.c (usbasp_spi_paged_write): Remove USBASP_BLOCKFLAG_LAST.
It is no longer needed, as we always write full pages now in paged
write mode.
This prevents each flash page from being written twice, where the
second attempt on older devices (ATmega64/128) signalled an immediate
"ready" condition when polling (likely a silicon bug) even though they
were still in progress. This caused the USBasp firmware to proceed,
and fill the page buffer anew which eventually caused the data
corruption.

t861, t88): In efuse (or hfuse for t26) read operation, turn all
bits in byte 3 from "x" to "o" (output); this is a first step
towards fixing the symptoms mentioned in the bug, by unifying the
behaviour between different AVRs. Not touched are the historic

and their respective AVR device support for doc/avrdude.texi.
* avrdude.1: Document all the STK600 stuff.
* doc/avrdude.texi: Ditto. Added a new chapter for
Programmer Specific Information.
Thanks to Eirik Rasmussen from Atmel Norway for his support in
getting this code running within that short amount of time!

the programmer backend.
jtagmkII.c: Implement the extended parameter jtagchain=
to support JTAG daisy-chains.
avrdude.1, doc/avrdude.texi: Document all of the above.

and link main.c against that library.
Add AC_PROG_RANLIB to configure.ac as we are building a library now.

* avrdude.conf.in (frank-stk200): Fix syntax error.
* ser_avrdoper.c: Make #ifdef for Win32/libhid
consistent with the initial check: use the HID driver
only iff found, otherwise use libusb.
