QAbstractSocket: wait with closing until all bytes have been written

only disconnect from host when all bytes have been written; i.e. not
only check whether the write buffer is empty, but also check whether
the socket engine has still bytes to write. This is necessary for
HTTP and SOCKS5 socket engine, because they both contain an inner TCP
socket which also does buffering. For the native socket engine, there
is no difference with this patch.
