bpo-43562: fix test_ssl to skip on unreachable network (GH-24937) (GH-25046)
This test checks result code of the connection directly, so it never raises an exception that can be suppressed by `support.transient_internet`. Directly support skipping the test in case of unreachable network.

bpo-42988: Remove the pydoc getfile feature (GH-25015)
CVE-2021-3426: Remove the "getfile" feature of the pydoc module which
could be abused to read arbitrary files on the disk (directory
traversal vulnerability). Moreover, even source code of Python
modules can contain sensitive data like passwords. Vulnerability
reported by David Schwörer.

It doesn't actually affect whether match_hostname() is called (it

bpo-43577: Fix deadlock with SSLContext._msg_callback and sni_callback (GH-24957)
OpenSSL copies the internal message callback from SSL_CTX->msg_callback to
SSL->msg_callback. SSL_set_SSL_CTX() does not update SSL->msg_callback
to use the callback value of the new context.
PySSL_set_context() now resets the callback and _PySSL_msg_callback()
resets thread state in error path.

bpo-43285 Make ftplib not trust the PASV response. (GH-24838)
bpo-43285: Make ftplib not trust the PASV response.
The IPv4 address value returned from the server in response to the PASV command
should not be trusted. This prevents a malicious FTP server from using the
response to probe IPv4 address and port combinations on the client network.
Instead of using the returned address, we use the IP address we're
already connected to. This is the strategy other ftp clients adopted,
and matches the only strategy available for the modern IPv6 EPSV command
where the server response must return a port number and nothing else.
For the rare user who _wants_ this ugly behavior, set a `trust_server_pasv_ipv4_address`
attribute on your `ftplib.FTP` instance to True.

Fix a race condition of test_stress_modifying_handlers() of
test_signal: only raise signals while we are in the
catch_unraisable_exception() context manager.
Moreover, don't check if we received at least one
signal if at least one signal got ignored.

bpo-43332: Buffer proxy connection setup packets before sending. (GH-24780)
We now buffer the CONNECT request + tunnel HTTP headers into a single
send call. This prevents the OS from generating multiple network
packets for connection setup when not necessary, improving efficiency.

[3.9] bpo-43406: Fix possible race condition where ``PyErr_CheckSignals`` tries to execute a non-Python signal handler (GH-24756) (GH-24761)
We can receive signals (at the C level, in `trip_signal()` in signalmodule.c) while `signal.signal` is being called to modify the corresponding handler. Later when `PyErr_CheckSignals()` is called to handle the given signal, the handler may be a non-callable object and would raise a cryptic asynchronous exception.

This lease on this domain has lapsed. This not only makes these dead links, but a potential attack vector for readers of python.org as the domain can be obtained by an untrustworthy party.
I considered redirecting these links to http://mingw-w64.org/ which is a maintained fork of mingw, but beyond my unfamiliarity with the exact level of compatibility, at the time of this PR that site had an expired cert and so is not much of a vulnerability fix.

There was a typo, we were checking if the "GITHUB_BASE_REF" string
literal was empty instead of the $GITHUB_BASE_REF value. When
$GITHUB_BASE_REF is empty, the action that triggered the run was not a
pull request, so we always run the full test suite.
