MDL-43975 Sessions: Should support memcache, not just memcached

This commit adds a session handler which works using memcache (without
requiring the memcached extension), similar to the support for
memcache within MUC.

This may be less reliable than memcached but we have been using a
similar approach on our system without problems. In case, I added a
warning in config-dist.php.
