Add support for using OpenSSL.
2001-05-04 Jeffrey Stedfast <fejj@ximian.com> * providers/smtp/camel-smtp-transport.c (connect_to_server): Add support for using OpenSSL. * camel-remote-store.c (remote_connect): Add support for using the OpenSSL implementation. * camel-tcp-stream-ssl.c (ssl_bad_cert): Hmmmm, don't pass in a NULL as the last argument to alert_user - prototype doesn't take that argument anymore? * camel-tcp-stream-openssl.c (camel_tcp_stream_openssl_finalize): (ssl_verify): Use a global hash table to try and lookup the CamelTcpStreamOpenSSL object given the ssl context since OpenSSL doesn't think one needs to pass data around, we should all be living in a world of global variables, duh! svn path=/trunk/; revision=9697
