TODO:
 - Remove assert(PyBytes_Check(opath)); from NullImporter_init() and zipimporter_init()
 - Fix setup_context() (_warnings.c)
 - Reencode module filenames if the system default encoding changes
 - Lib/unittest/runner.py and Lib/test/test_subprocess.py contain hacks to fix tests. It might be rewritten
 - Fix the 3 "FIXME: use _Py_char2wchar" in getpath.c

I restored code setting the system encoding.

The patch fixes also _posixsubprocess.fork_exec() to support undecodable current working directory.
