Hash :d96457e1 Message :listener: Preserve last error in evconnlistener_new_bind() before close
In function evconnlistener_new_bind() after go to "err:", The
evutil_closesocket() would clear the error code( I found this under
Windows ). User can not use EVUTIL_SOCKET_ERROR() to get the
evconnlistener_new_bind()'s failing error.
I add a err_code variable to store and restore the last error code.
v2: rebased by azat to make the patch simpler
