Redesign XDS110 JTAG Debugger

I have redesigned the XDS110 debugger with isolated pinout. The connector is also redesigned. Now a cable is used so that it is more flexible for different applications. Btw, instead of using the TI standard 14-pin header, a 10-pin 1.27mm pitch header is used. The smaller pin header is more easy to use for smaller PCB.
