Summary: socketmodule SSL free calls in wrong order

Initial Comment:
I was examining socketmodule.c and notice the following ordering of 
allocation and deallocation regarding SSL.

    static SSLObject *
    newSSLObject(PySocketSockObject *Sock, char *key_file, char *cert_file)
    {
        ...
        self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */
        ...
        self->ssl = SSL_new(self->ctx); /* New ssl struct */
        ...
    }

    static void SSL_dealloc(SSLObject *self)
    {
        ...
        SSL_CTX_free(self->ctx);
        SSL_free(self->ssl);
        ...
    }

Perhaps it works for now, but I think that the order of free() calls in
SSL_dealloc should be reversed.

I believe it is easy to fix (see attached patch), but I
don't have a way of testing it.  There appears to be no
regression test for SSL support, nor is there documentation,
so I have no idea how to /use/ the SSL support in socket module.

Assigning back to Jeremy to double check the patch.

Barry, This is a memory leak/free problem, right? So you 
get it.  Seriously, sounds like this would be easy to fix.
