Patch for OpenSSH-7.7p1 to compile with OpenSSL-1.1.0

This is a patch for OpenSSH-7.7p1 to build with OpenSSL-1.1.0 . By default OpenSSH-7.7p1 only supports up to OpenSSL-1.0.x versions. This patch will build and pass all "make tests" regressions using OpenSSL-1.1.0.

This patch breaks support for OpenSSL-1.0.x, so don't use this patch if you need 1.0.x support. This patch doesn't introduce new shim functions to emulate OpenSSL-1.1.x API on 1.0.x .

Some obsolete OS may not pass the last test_utf8 test; use env TEST_SSH_UTF8=no ./configure ... to skip the test.

Since sshd invoked during the tests will try to chown("/dev/ttyp1", user, ttygid), key-options.sh test may fail. Do ssh localhost, then logout, then run make tests on such platforms (obsolete BSD variants).

Similar, but independent approaches
