[Python-3000] to be merged

> - SSL changes

I've been maintaining the Lib/ssl.py, Lib/test/test_ssl.py and
Modules/_ssl.c files separately for the two trees.  I think the
underlying changes in socket.py, and the IO subsystem, still make this
a good idea, but I'm willing to be convinced differently.

There's yet a third variant of this code for pre-2.6 in the PyPI
distribution of it.
