PyErr_NormalizeException(): in the type==NULL test, we should simply
return. Setting an exception can mess with the exception state, and
continuing is definitely wrong (since type is dereferenced later on).
Some code that calls this seems to be prepared for a NULL exception
type, so let's be safe rather than sorry and simply assume there's
nothing to normalize in this case.
Provide access to the import lock, fixing SF bug #580952. This is
mostly from SF patch #683257, but I had to change unlock_import() to
return an error value to avoid fatal error.
Circular reference makes Py_Init crash
Modified to keep _Py_ResetReferences() API, but make it a no-op.
It's not called now (for 2.3 it was completely removed).

Add C API PyUnicode_FromOrdinal() which exposes unichr() at C level.
u'%c' will now raise a ValueError in case the argument is an
integer outside the valid range of Unicode code point ordinals.
Closes SF bug #593581.
patch #617312, both on the trunk and the 22-maint branch.
Also added a test case, and ported the test_trace I wrote for HEAD
to 2.2.2 (with all those horrible extra 'line' events ;-).
