use the right tool for the job!
use BITMODE_BITBANG for bulk transfers and BITMODE_BBSYNC for transfers with
interleaved reads

increase programming speed by a factor of 4.
it now takes 5 seconds to program a xc3s400, which is the same time it
takes to program this chip with a parallel cable.

* using synchronous bitbang mode
* handling multi transfers in the jtagkey-driver by combining writes and reads
