Per
https://codereview.chromium.org/994743003/diff/1/net/socket/ssl_server_socket...,
don't forward-declare this type.

[pneubeck (no reviews), 2015/08/20 07:18:23]

Done. I think we should fix all such existing forward declarations, as they give
the wrong impression to new developers that this is the correct way of doing it.
