* buspirate.c: Turn the "cmd" argument of the various methods into
a "const unsigned char *"; while doing this, declare all arrays being
passed as arguments to be pointers rather than arrays, as the latter
obfuscates the way arrays are being passed to a callee in C.

* avrftdi*.*: changed include check for libftdi/libusb, deactivate 232H if not available
* ft245r.c: changed include check for libftdi/libusb

* avrdude.conf.in: fixed buff pins of avrftdi programmers (low active buffer need now inverted numbers)
* avrftdi*.*: accept also old libftdi (0.20 still works with it), added powerup to initialize
* ft245r.c: accept libftdi1, code cleanup and make it more similar to avrfdti (os they might be merged someday)

Generic function enabling external programming on TPI devices. This
function sets the required guard time (which is passed in as parameter),
checks the TPI identification register, writes SKEY command + SKEY, and
finally polls the NVMEN bit in TPISR.
avr.h: Add prototype definitions of avr_tpi_program_enable() and
avr_tpi_chip_erase().
avrftdi_tpi.c: Removes tpi_skey_cmd array, containing the SKEY command
and the SKEY bytes.
tpi.h: Adds tpi_skey_cmd array, containing the SKEY command and the SKEY
bytes, but in the reverse order of tpi_skey.

This is not necessary any more, because the "frame" ends in logic 1, so
the pin is high anyway and the MPSSE keeps the pin value as long as it
is idle. Setting the pin low would cause the TPI physical layer in the
AVR part to detect a collision.

All I/O of avrftdi_tpi is done in terms of pgm->cmd_tpi() calls instead
of calling avrftdi_tpi_[read,write]_byte() functions directly.

avrftdi_private.h, avrftdi.c: remove pdata->guard_bits refernces, since
they are no longer needed
avrftdi_tpi.c: Use fixed guard time of 2 bits, this gives 16 bits per
frame. tpi_byte2frame() and tpi_frame2byte() functions are now
symmetrical and extraction of received data in avrftdi_read_byte is less
complicted. Write the new guard time to the TPI in
avrftdi_tpi_program_enable().

In this function the NVM enable bit in TPISR is written to zero, like
described in AVR918. The reset line is released in avrftdi_close().

Device identification is possible tested under OS X 10.6.8 with an
FT4232H and ATtiny10.
