[New-bugs-announce] [issue21965] Add support for Memory BIO to _ssl

New submission from Geert Jansen:

The attached patch adds a _MemoryBIO type to _ssl, and a _wrap_bio() method to _SSLContext. The patch also includes tests.

For now I kept _wrap_bio() and _MemoryBIO semi-private. The reason is that it returns an _SSLSocket instead of an SSLSocket and this type has not been exposed before as part of the public API. Changing the result of _wrap_bio to return an SSLSocket is not appropriate IMHO because it should not inherit from socket.socket which would waste a file descriptor and None of the IO methods are relevant.

The patch works for me and gives no errors with --with-pydebug. I've also used it in an experimental branch of Gruvi and all the tests pass there too.
