• fix memory leak which occured with explicit stop_SSL in connection with non-blocking sockets or timeout - https://rt.cpan.org/Ticket/Display.html?id=125867 Thanks to Paul Evans for reporting
• fix redefine warnings in case Socket6 is installed but neither IO::Socket::IP nor IO::Socket::INET6 - https://rt.cpan.org/Ticket/Display.html?id=124963
• IO::Socket::SSL::Intercept - optional 'serial' argument can be starting number or callback to create serial number based on the original certificate
• new function get_session_reused to check if a session got reused
• IO::Socket::SSL::Utils::CERT_asHash: fingerprint_xxx now set to the correct value
• fix t/session_ticket.t: it failed with OpenSSL 1.1.* since this version expects the extKeyUsage of clientAuth in the client cert also to be allowed by the CA if CA uses extKeyUsage

Passed the make tests. Installed and run 'youtube-viewer'.
