[debian-mysql] Bug#787118: Bug#787118: mariadb-server-10.0: Compile with OpenSSL (instead of YaSSL)

[Otto Kekäläinen]

CYaSSL cannot be used until MariaDB core developers confirm that it is
feature complete enough to work with MariaDB (and vice versa MariaDB
is compatible with the CYaSSL API).

OpenSSL cannot be used unless OpenSSL users give an explicit
permission for the OpenSSL and MariaDB server process combination
(according to Clint Byrum in #761911).
