helper module _ssl.

The support for the RAND_* APIs in _ssl is now only enabled
for OpenSSL 0.9.5 and up since they were added in that
release.

Note that socketmodule.* should really be renamed to _socket.* --

and compiles don't give errors or warnings.

WARNING: This patch does *not* include changes to the various
non-Unix build process files.

Fix exit races in test_thread.py and test_threaded_import.py.
I suspect the bug is provokable only under Linux (where child threads
seem to get lots of cycles before they get killed after the main thread
exits), or on multi-processor machines running other OSes.

- Override existing symlinks in the framework.

Ensure we also build on VC7.  Involves replacing largeint.h helper functions with msvc's native 64 bit integers.
