bug #30559 Ft232 bit-bang support 

* ft245r.[ch]: new programmer type implementation
* configure.ac: add pthread as link library
* avrdude.conf.in: added some new programmers
* Makefile.am: added new source files to compile
* pindefs.h: change PIN_MASK, PIN_INVERSE to highest bit of unsigned int
* pgm.[ch]: added generic function to print pin assignments (taken from par.c)
* par.c: moved pin assigment print function to pgm.c

/*
The ft232r is very similar, or even "identical" in the synchronous
bitbang mode that we use here.
This allows boards that have an ft232r for communication and an avr
as the processor to function as their own "ICSP". Boards that fit
this description include the Arduino Duemilanove, Arduino Diecimila,
Arduino NG (http://arduino.cc/it/main/boards) and the BitWizard
ftdi_atmega board (http://www.bitwizard.nl/wiki/index.php/FTDI_ATmega)
The Arduinos have to be patched to bring some of the control lines
to the ICSP header. The BitWizard board already has the neccessary
wiring on the PCB.
How to add the wires to an arduino is documented here:
http://www.geocities.jp/arduino_diecimila/bootloader/index_en.html
