738621d047
This patch changes the `ScriptedThread` initializer in couple of ways: - It replaces the `SBTarget` parameter by a `SBProcess` (pointing to the `ScriptedProcess` that "owns" the `ScriptedThread`). - It adds a reference to the `ScriptedProcessInfo` Dictionary, to pass arbitrary user-input to the `ScriptedThread`. This patch also fixes the SWIG bindings methods that call the `ScriptedProcess` and `ScriptedThread` initializers by passing all the arguments to the appropriate `PythonCallable` object.
