Log:
  openssh: cherry-pick OpenSSL 1.1.1 compatibility
  
  Compatibility with existing OpenSSL versions is maintained.
  
  Upstream commits:
  482d23bcac upstream: hold our collective noses and use the openssl-1.1.x
  48f54b9d12 adapt -portable to OpenSSL 1.1x API
  86e0a9f3d2 upstream: use only openssl-1.1.x API here too
  a3fd8074e2 upstream: missed a bit of openssl-1.0.x API in this unittest
  cce8cbe0ed Fix openssl-1.1 fallout for --without-openssl.
  
  Trivial conflicts in sshkey.c and test_sshkey.c were resolved.
  
  Connect libressl-api-compat.c to the build, and regenerate config.h
