Fix the backdoor server error on PyPy: there is a weakreference somewhere keeping socket objects alive or a finalizer is involved so a judicious GC fixes the hangs...but ideally the dangling reference gets found and fixed.

Under PyPy, make the main greenlet look like the MainThread. This fixes many of the threading related tests.

Work around missing sslwrap in Python 2.7.9 (fixes #477) #481

Bug/ py3k acquire. See gevent/gevent#496

Handle server_hostname and _context in SSLv2 SSLSocket

With the backport of SNI code from Python 3 to Python 2.7.x, Python's
ssl.py is now passing server_hostname and _context into SSLv2's
SSLSocket, rather than just SSLv3's SSLSocket, so we need to handle
those arguments.
