The debugger wire handler is implemented similarly to the io event handler. A dedicated thread monitors the debugger port for incoming connection requests. When a debugger is connected, the VM sends events messages over the wire and handles debugger requests. To start the VM with a debugger connection, use the option --debug:<portnumber>. The VM pauses at the beginning of main() and waits for a debugger to connect. Subsequent changes will implement debugger commands one by one. With this change, the VM only understands "resume" commands.
