Partial fix for bug #1306 Multiple reinitializations of Python 3.0 failed on a system without a hardcoded default fs encoding. The patch makes sure that the default fs encoding is freed and reset to NULL on e.g. Linux. I've also taken the liberty to increase the debugging in Objects/object.c:_Py_ForgetReference(). The method is used to validate the reference chain. Reinitialization still fails in the 3rd round of my test suite: * ob object : <refcnt 0 at 0x821c840> type : str refcount: 0 address : 0x821c840 * op->_ob_prev->_ob_next object : <refcnt 0 at 0x821c840> type : str refcount: 0 address : 0x821c840 * op->_ob_next->_ob_prev object : bytearray(b'') type : bytearray refcount: 1 address : 0x826b838 Fatal Python error: UNREF invalid object
