[issue4438] Add an easy way to __import___ submodules

Corrections and clarifications:

 * I'd say labeling the patch naive and "breaking things" was misleading
(there was a breakage that resulted from stale files with incorrect
permissions from my previous build of Python 2.6; after a make distclean
all tests passed as described above). The patch is correct and
backwards-compatible in Python level, but it introduces a change in the
C API:

 PyAPI_FUNC(PyObject *) PyImport_ImportModuleLevel(char *name,
-       PyObject *globals, PyObject *locals, PyObject *fromlist, int level);
+       PyObject *globals, PyObject *locals, PyObject *fromlist,
+       int level, char submodule);


 * The patch was made against Python 2.6 release source.

 * The argument is named 'submodule' instead of 'toplevel' to avoid
confusion with 'level'.
