Subject: [PATCH] Add new error category and constant for
 ssl::error::stream_truncated.

This error replaces uses of SSL_R_SHORT_READ, and indicates that the
SSL stream has been shut down abruptly. (I.e. the underlying socket
has been closed without performing an SSL-layer shutdown.)

Subject: [PATCH] Add compatibility with OpenSSL 1.1 - SSLv2 has been
 completely removed from OpenSSL, even without OPENSSL_NO_SSL2 - there is a
 new threading API without locking callbacks - struct SSL_CTX has been made
 opaque and must be used via accessor functions - some cleanup functions have
 been removed

Subject: [PATCH] Fix compilation with OpenSSL 1.1 API

With OPENSSL_API_COMPAT=0x10100000L, SSL_library_init, SSL_load_error_strings, and OpenSSL_add_all_algorithms are removed.
With OPENSSL_API_COMPAT=0x10000000L, these are function-style macros mapping to OPENSSL_init_ssl, which is called automatically anyway.
