- renamed jtag_interface_t.support_statemove to jtag_interface_t.support_pathmove (it is used to indicate jtag_add_pathmove support)
- fixed small bug in str7x.c that printed an address instead of the target number in an error message
- added support for Olimex ARM-USB-OCD. The new ft2232 layout is called "olimex-jtag"
