Fix build with LibreSSL 2.7

LibreSSL 2.7 added a large part of the OpenSSL 1.1 API.
 - Rename LIBRESSL_IN_USE to LIBRESSL_1_0_API (LibreSSL with
   OpenSSL 1.0 API)
 - Add LIBRESSL_1_1_API for ifdef blocks where the 1.1 API in
   LibreSSL is incomplete
 - Use OPENSSL_NO_PSK to detect missing PSK feature (not LibreSSL
   specific)
