<p>Send and receive functions with timeouts have been added

<p>Accordingly a new compiler option <c>{c_timeout, {SendTimeout, RecvTimeout}}</c> has been added. Timeouts
are specified in milliseconds.</p>
<p>A user that want to implement its own protocols with
function timeouts has to implement the following functions.</p>
<p>For C clients the functions <c>int PFX_send_notification(CORBA_Environment *env, unsigned int send_ms)</c>, and <c>int PFX_send_request_and_receive_reply(CORBA_Environment *env, unsigned int send_ms, unsigned int recv_ms)</c>
have to be additionally implemented, where PFX is the
user defined prefix.</p>
<p>For C servers no additional functions have to be
implemented, but a clone of the <c>int oe_server_receive_tmo(CORBA_Environment *env, oe_map_t *map, unsigned int send_ms, unsigned int recv_ms)</c>
might be handy.</p>
