so that we can do Python scripting like this:
target = self.dbg.CreateTarget(self.exe)
self.dbg.SetAsync(True)
process = target.LaunchSimple(None, None, os.getcwd())
process.PutSTDIN("Line 1 Entered.\n")
process.PutSTDIN("Line 2 Entered.\n")
process.PutSTDIN("Line 3 Entered.\n")
Add TestProcessIO.py to exercise the process IO API: PutSTDIN()/GetSTDOUT()/GetSTDERR().
