			OpenSSL can be build without support for TLS 1.0 and 1.1. The ssl module now correctly adheres to OPENSSL_NO_TLS1 and OPENSSL_NO_TLS1_1 flags. Also update multissltest to test with latest OpenSSL and LibreSSL releases. Signed-off-by: Christian Heimes <christian@python.org> Automerge-Triggered-By: @tiran

| """Run Python tests against multiple installations of OpenSSL and LibreSSL
 | |
| 
 | |
| The script
 | |
| 
 | |
|   (1) downloads OpenSSL / LibreSSL tar bundle
 | |
|   (2) extracts it to ./src
 | |
|   (3) compiles OpenSSL / LibreSSL
 | |
|   (4) installs OpenSSL / LibreSSL into ../multissl/$LIB/$VERSION/
 | |
|   (5) forces a recompilation of Python modules using the
 | |
|       header and library files from ../multissl/$LIB/$VERSION/
 | |
|   (6) runs Python's test suite
 | |
| 
 | |
| The script must be run with Python's build directory as current working
 | |
| directory.
 | |
| 
 | |
| The script uses LD_RUN_PATH, LD_LIBRARY_PATH, CPPFLAGS and LDFLAGS to bend
 | |
| search paths for header files and shared libraries. It's known to work on
 | |
| Linux with GCC and clang.
 | |
| 
 | |
| Please keep this script compatible with Python 2.7, and 3.4 to 3.7.
