Description: Backport of TLS 1.3 related fixes from 3.7. Misc fixes and workarounds for compatibility with OpenSSL 1.1.1 from git master and TLS 1.3 support. With OpenSSL 1.1.1, Python negotiates TLS 1.3 by default. Some test cases only apply to TLS 1.2. OpenSSL 1.1.1 has added a new option OP_ENABLE_MIDDLEBOX_COMPAT for TLS 1.3. The feature is enabled by default for maximum compatibility with broken middle boxes. Users should be able to disable the hack and CPython's test suite needs it to verify default options Signed-off-by: Christian Heimes christian@python.org (cherry picked from commit 2a4ee8a) https://bugs.python.org/issue32947
