Please disregard this patch. I ended up adding TPI support to ftdi_syncbb instead, so this is no longer needed.

This patch adds a ftdi_bb programmer type. Unlike the ft245r driver, this one does all the heavy lifting through bitbang.c and hence supports TPI. It can be built both using libftdi1 or FTDI's FTD2XX library (which seems to be much easier to install on Windows).

On Linux, a 1KiB flash can be written in about 3 seconds. Windows seems to be about 10 times slower.
