Ehm, three unrelated changes. - Add Py_FrozenFlag, intended to suppress error messages fron getpath.c in frozen binaries. - Add Py_GetPythonHome() and Py_SetPythonHome(), intended to allow embedders to force a different PYTHONHOME. - Add new interface PyErr_PrintEx(flag); same as PyErr_Print() but flag determines whether sys.last_* are set or not. PyErr_Print() now simply calls PyErr_PrintEx(1).
