  This contains a number of things:

  1) Improve the documentation of the SSL module, with a fuller
     explanation of certificate usage, another reference, proper
     formatting of this and that.

  2) Fix Windows bug in ssl.py, and general bug in sslsocket.close().
     Remove some unused code from ssl.py.  Allow accept() to be called on
     sslsocket sockets.

  3) Use try-except-else in import of ssl in socket.py.  Deprecate use of
     socket.ssl().

  4) Remove use of socket.ssl() in every library module, except for
     test_socket_ssl.py and test_ssl.py.

Certificates in general are part of a public-key / private-key system. In this system, each *principal*,

time period over which it is valid. This is expressed as two fields,
called "notBefore" and "notAfter".
The underlying system which is used in the Python SSL support is
called "OpenSSL". It contains facilities for constructing and
validating certificates. In the Python use of certificates, the other
side of a network connection can be required to produce a certificate,
and that certificate can be validated against a file filled with
self-signed *root* certificates (so-called because the issuer is the
same as the subject), and and "CA" (certification authority)
certificates assured by those root certificates (and by other CA
certificates). Either side of a connection, client or server, can
request certificates and validation, and the connection can be optionally
set up to fail if a valid certificate is not presented by the other side.
In the Python use of certificates, a client or server
can use a certificate to prove who they are. The other
side of a network connection can also be required to produce a certificate,
and that certificate can be validated to the satisfaction
of the client or server that requires such validation.
The connection can be set to fail automatically if such
validation is not achieved.
Python uses files to contain certificates. They should be formatted
as "PEM" (see :rfc:`1422`), which is a base-64 encoded form wrapped
with a header line and a footer line::
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
The Python files which contain certificates can contain a sequence
of certificates, sometimes called a *certificate chain*. This chain
should start with the specific certificate for the principal who "is"
the client or server, and then the certificate for the issuer of that
certificate, and then the certificate for the issuer of *that* certificate,
and so on up the chain till you get to a certificate which is *self-signed*,
that is, a certificate which has the same subject and issuer,
sometimes called a *root certificate*. The certificates should just
be concatenated together in the certificate file. For example, suppose
we had a three certificate chain, from our server certificate to the
certificate of the certification authority that signed our server certificate,
to the root certificate of the agency which issued the certification authority's
certificate::
-----BEGIN CERTIFICATE-----
... (certificate for your server)...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
... (the certificate for the CA)...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
... (the root certificate for the CA's issuer)...
-----END CERTIFICATE-----
If you are going to require validation of the other side of the connection's
certificate, you need to provide a "CA certs" file, filled with the certificate
chains for each issuer you are willing to trust. Again, this file just
contains these chains concatenated together. For validation, Python will
use the first chain it finds in the file which matches.
Some "standard" root certificates are available at
http://www.thawte.com/roots/ (for Thawte roots) and
http://www.verisign.com/support/roots.html (for Verisign roots).

# socket isn't closed until they are all closed.
