mkII. The serial transport methods have been moved out into a record of function pointers for that purpose, defaulting to the actual serial connection that natively applies to the hosting system. Iff inside the JTAG ICE mkII handler a port name starting with "usb" has been detected, the record of function pointers is switched to USB. Optionally, a serial number might be specified, so only the JTAG ICE mkII matching the given serial number will be opened. The match is done right-to-left, so only the least significant bytes of the serial number need to be given. In order to make the change as least intrusive to existing drivers as possible, the entire naming scheme of the serial_foo() function entry points has been maintained as access macros that encapsulate these into the respective indirect function calls via serdev->foo(). git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk/avrdude@478 81a1dc3b-b13d-400b-aceb-764788c761c2
