update parallel code for py3k...

update parallel code for py3k This is primarily tweaks of bytes/unicode, but other fixes include: * some integer division * added co_kwonlyargcount to code objects * a few places to handle map/range being objects non-copying numpy is disabled on py3k, because arrays are not reconstructed properly on the other side. This is because pyzmq always receives a byte array (memoryview.itemsize=1), which confuses numpy. With these changes, almost all parallel tests pass. Notable exceptions are: sync_imports, and MUX engine death.
