Send search requests to server only after bind succeeded.

There are server implementations that ignore a search request if
it is sent in the same packet as the bind request, apparently
leaving it in some server side buffer. If another search request
is received by the server afterwards, it suddenly discovers the first
search request, handles it, and then proceeds to handle the second one.
So we now buffer all search requests we want to forward to the server
until we received a positive bind response from the server.
