hweisbach 8b4c54e37f avrftdi: Set guard time to fixed 2 bits. 
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().

hweisbach d61242c19c avrftdi_tpi.c: Adds avrftdi_tpi_disable() 
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().

hweisbach a29fc23148 Adds initial avrftdi TPI support. 
Device identification is possible tested under OS X 10.6.8 with an
FT4232H and ATtiny10.
