DER_cert_to_PEM_cert() used textwrap.fill() to format PEM.
But it's library to wrap lines on word boundary, while PEM is
base64 encoded string.
Additionally, importing textwrap is little slow.
SSLSocket.wrap_bio() and SSLSocket.wrap_socket() hard-code SSLObject and
SSLSocket as return types. In the light of future deprecation of
ssl.wrap_socket() module function and direct instantiation of SSLSocket,
it is desirable to make the return type of SSLSocket.wrap_bio() and
SSLSocket.wrap_socket() customizable.

The SSL module now raises SSLCertVerificationError when OpenSSL fails to
verify the peer's certificate. The exception contains more information about
the error.

* bpo-29136: Add TLS 1.3 support
TLS 1.3 introduces a new, distinct set of cipher suites. The TLS 1.3
cipher suites don't overlap with cipher suites from TLS 1.2 and earlier.
Since Python sets its own set of permitted ciphers, TLS 1.3 handshake
will fail as soon as OpenSSL 1.1.1 is released. Let's enable the common
AES-GCM and ChaCha20 suites.
Additionally the flag OP_NO_TLSv1_3 is added. It defaults to 0 (no op) with
OpenSSL prior to 1.1.1. This allows applications to opt-out from TLS 1.3
now.

* bpo-27340: Use memoryview in SSLSocket.sendall()
SSLSocket.sendall() now uses memoryview to create slices of data. This fix
support for all bytes-like object. It is also more efficient and avoids
costly copies.

* Cast view to bytes, fix typo

The deprecation include manual creation of SSLSocket and certfile/keyfile
(or similar) in ftplib, httplib, imaplib, smtplib, poplib and urllib.
ssl.wrap_socket() is not marked as deprecated yet.
The options OP_NO_COMPRESSION, OP_CIPHER_SERVER_PREFERENCE, OP_SINGLE_DH_USE, OP_SINGLE_ECDH_USE, OP_NO_SSLv2 (except for PROTOCOL_SSLv2), and OP_NO_SSLv3 (except for PROTOCOL_SSLv3) are set by default. The initial cipher suite list contains only HIGH ciphers, no NULL ciphers and MD5 ciphers (except for PROTOCOL_SSLv2).
add private method to enum to support replacing global constants with Enum members:
- search for candidate constants via supplied filter
- create new enum class and members
- insert enum class and replace constants with members via supplied module name
- replace __reduce_ex__ with function that returns member name, so previous Python versions can unpickle
modify IntEnum classes to use new method
ssl.PROTOCOL_SSLv23 protocol by default, not ssl.PROTOCOL_SSLv3, for maximum
compatibility and support platforms where ssl.PROTOCOL_SSLv3 support is
disabled.
