Make the driver more flexible and define adapter-specific configurations in Tcl instead of C using the adapter GPIO subsystem. The rework also includes coding style fixes and improvements of the documentation. All modifications are done such that backwards compatibility is ensured. Tested with Olimex ARM-JTAG cable [1] and APM32F103 target device on Linux and FreeBSD. The driver works on Linux using direct I/O and PPDEV. On FreeBSD, only PPDEV works. The build with direct I/O already failed before the patch. This problem will be fixed in a subsequent patch. The patch is not tested on Windows because there is no documentation for it.
