SBProcess.PutSTDIN() needs to be properly typemapped when swigging,

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().
