- disabled FT2232 debug output (that code should be fairly stable)

- fixed bug in jtag.c where JTAG command type was wrong for PATHMOVE commands
- added lattice ISP cable (experimental)
- properly initialize parallel port (clear tristate bit)
- fixed jtag/Makefile.am that failed with some versions of autotools
- print error number if read() in gdbserver.c failed on Windows
- fixed handling of opcodes with bits 27-25 b011 (comment was correct, code had a bug)
- added support for AT91SAM7SE internal flash
