bpo-38659: [Enum] add _simple_enum decorator (GH-25285)
add:

_simple_enum decorator to transform a normal class into an enum
_test_simple_enum function to compare
_old_convert_ to enable checking _convert_ generated enums
_simple_enum takes a normal class and converts it into an enum:

@simple_enum(Enum)
class Color:
    RED = 1
    GREEN = 2
    BLUE = 3

_old_convert_ works much like _convert_ does, using the original logic:

# in a test file
import socket, enum
CheckedAddressFamily = enum._old_convert_(
        enum.IntEnum, 'AddressFamily', 'socket',
        lambda C: C.isupper() and C.startswith('AF_'),
        source=_socket,
        )

test_simple_enum takes a traditional enum and a simple enum and
compares the two:

# in the REPL or the same module as Color
class CheckedColor(Enum):
    RED = 1
    GREEN = 2
    BLUE = 3

_test_simple_enum(CheckedColor, Color)

_test_simple_enum(CheckedAddressFamily, socket.AddressFamily)

Any important differences will raise a TypeError

bpo-36076: Add SNI support to ssl.get_server_certificate. (GH-16820)
Many servers in the cloud environment require SNI to be used during the
SSL/TLS handshake, therefore it is not possible to fetch their certificates
using the ssl.get_server_certificate interface.

This change adds an additional optional hostname argument that can be used to
set the SNI. Note that it is intentionally a separate argument instead of
using the host part of the addr tuple, because one might want to explicitly
fetch the default certificate or fetch a certificate from a specific IP
address with the specified SNI hostname. A separate argument also works better
for backwards compatibility.

bpo-41282: (PEP 632) Load install schemes from sysconfig (GH-24549)
With this patch, `distutils.command.install.INSTALL_SCHEMES` are loaded from
`sysconfig._INSTALL_SCHEMES`.

The distutils module is deprecated and will be removed in 3.12 (PEP 632).
This change makes the `sysconfig._INSTALL_SCHEMES` the single point of truth
for install schemes while keeping `distutils.command.install.INSTALL_SCHEMES`
exactly the same. If we, during the transition to the sysconfig, change
something, this makes sure that it also propagates to distutils until the
module gets removed.

Moreover, as discussed [on Discourse], Linux distros need to patch
distutils/sysconfig to make sure the packages will land in proper locations.
This patch makes it easier because it leaves only one location where install
schemes are defined which is much easier to patch/adjust.

[on Discourse]: https://discuss.python.org/t/pep-632-deprecate-distutils-module/5134

The implementation is slightly different than the plan but I think it's the
easiest way how to do it and it also makes the downstream patch simple,
flexible and easy to maintain.

It's also necessary to implement this before setuptools starts bundling
the distutils module so the default install schemes stay in the standard library.

The removed code from sysconfig does not seem to have any negative effect
because, honestly, it seems that nothing actually uses the install schemes
from sysconfig at all. There were many big changes in these modules where
they were trying to include packaging in stdlib and then reverted that.
Also, the test of distutils install command does not count with the different
locations which is good evidence that the reason to have this piece of code
is no longer valid.
