Bug#12897501 REPLICATION DOES NOT SUPPORT WINDOWS AUTH PLUG-IN

Browse source 
Connection of slave to master using a replication account which authenticates
with an external plugin was not possible.

Fixed by making sure that the CLIENT_PLUGIN_AUTH capability is set when client connects using mysql_real_connect(). Also, a plugin-dir path used by client library to locate authentication plugins is set based on the analogous server setting. This is done in connect_to_master() function before a call to mysql_real_connect().
