The "PEP 8 compliant" API for multiprocessing and threading needs to be
cleaned up before release as per the thread on python-dev. The release
manager gave approval for this change during that discussion [1].

Changes needed:
- remove Py3k warnings from the threading module (old API is going to be
kept around even in Py3k)
- change get_name/set_name into a "name" property
- change is_daemon/set_daemon into a "daemon" property

(Note that changing "is_alive" to be a property is not on that list -
that can be a fairly expensive thing to check for the multiprocessing
library. I also left out active_count(), as I think the underscore adds
clarity in that case)
