`ssl.wrap_socket()` is deprecated in CPython, so use `SSLContext` instead,
so the example is a good example to copy.

The main changes here are to pass the address family and socket type to
`getaddrinfo()`, and then use the result of the address lookup when
creating the socket, so it has the correct address family.
This allows both IPv4 and IPv6 to work, because the socket is created with
the correct AF_INETx type for the address.
Also add some more comments to the examples to explain what's going on.
Fixes issue #15580.

Non-blocking SSL streams can be difficult to get right, so provide a
working example, of a HTTPS client.

It's better for discoverability to have these examples named `https_xxx.py`
rather than `http_xxx_ssl.py`.

Name recv() based a "simplistic", as it can't work robustly in every
environment. All this is to let people concentreate on proper, read()-
based one (and to turn recv() based into a "negative showcase",
explaining what are the pitfalls of such approach).
Since "read-exactly" stream refactor, where stream.read(N) will read
exactly N bytes (unless EOF), http_server* examples can't any longer do
client_socket.read(4096) and expect to get full request (it will block
on HTTP/1.1 client). Instead, read request line by line, as the HTTP
protocol requires.
