The default query type for QNetworkProxyQuery is TcpSocket (that's what
our QNetworkProxy::applicationProxy() requests). Unfortunately, this
can result in http_proxy found and QTcpServer::listen() failing
(probably, QUdpSocket is also affected). So now we extract applicationProxy's
logic but modify it to provide the exact query type we need.

There is no need in additional polling, because readyRead() signal of
the inner socket is directly connected to the slot which extracts the
datagrams. Moreover, calling _q_udpSocketReadNotification() from the
engine code might cause the spurious notifications both in the outer
and inner sockets.

Similar to the way datagrams are handled for udp sockets the worker now
takes care of tcp data. Thus we avoid race conditions which stopped data
processing. It could happen that data was read from the socket into the
buffer and before readyRead was emitted the buffer was completely read.
In this case readNotification is set to false and no new data is processed
afterwards.
Additionally the buffer was replaced by a vector of QByteArray. The buffer
kept growing and was never cleared (and there is no obvious way for
clearing the buffer), so that an overflow happened eventually.
pendingReadOperations (and its mutex) could be removed as well. There is
only one situation where they could clash and that's the initial read.
Having two members is preferred over having a list of operations and a
mutex.

When a client connects and sends data immediately it was possible that
initial data was lost as the state was set too late. If the callback was
called before the state was set the socket engine just discarded the
data. So the state has to be set before the callback is registered.
The new implementation needs a list of pending read operations. It can
happen that the "readyRead" callback is triggered directly while
"put_Completed" is called. The callback reassigns readOp which causes a
"function not implemented" exception when it jumps back to the
"put_Completed" call in "initialize"

Instead of calculating the bytesAvailable in place, the value should
be stored and only retrieved in the function itself. Otherwise it is
possible that bytesAvailable is called between the data having been
read and readyRead is emitted. In this case it's possible, that the
client reads all the data before the signal is emitted. Triggering
readyRead without any data being available will stop the socket.

We may only emit the readReady signal once for every event loop
iteration. The previous implementation lead to the situation that the
socket engine stopped reading socket data when bursts of data was
received. In this case several readReady signals were fired. The socket
engine obtained the pending datagrams (not only the first one) and for
the following readReady signal no datagram was present. In this case the
socket engine stops reading and the engine stalls.
The new approach emits the readyRead signal at the most once every event
loop iteration. The list of new pending datagrams is queued to be added
to the "real" pending datagram list at the same time as the readyRead
signal. Thereby we avoid the situation that a client can read all the
datagrams before readyRead is emitted.
One more advantage of having the worker handle the pending datagrams
is that we no longer have to access the socket engine's members inside
the callback. Thus we avoid the situation, where a late callback can
make the application crash when the socket engine has already been
deleted.
