ffmpeg | branch: master | Martin Storsjö <martin at martin.st> | Fri Jul 27 20:22:51 2012 +0300| [41ecbbc7aa3d491cc9d8d425634c5901eefa088a] | committer: Martin Storsjö

tls: Return AVERROR_EOF if the TLS_read/write functions return 0

OpenSSL returns 0 when the peer has closed the connection. GnuTLS
doesn't return that though, but returns
GNUTLS_E_UNEXPECTED_PACKET_LENGTH if the connection simply is closed
without a clean close notify packet.
