a4d26cf522 QWindowsPipeWriter: ensure validity of the write buffer
QWindowsPipeWriter uses asynchronous API to perform writing. Once a cycle
has been started, the write buffer must remain valid until the write
operation is completed.

To avoid data corruption and possibly undefined behavior, this patch
makes QWindowsPipeWriter::write() take a QByteArray, which it keeps alive
for the duration of the write cycle.

24411e9743 Add a write buffer to QLocalSocket/Win
Commit 0307c008 removed the buffering of data-to-be-written from
QWindowsPipeWriter, because it was assumed that users of this class
(QProcess and QLocalSocket) already buffer data internally.

This assumption was wrong for QLocalSocket. The following sequence
    localSocket->write(someData);
    localSocket->write(someMoreData);
would not write anything on the second write.

Add a write buffer to the Windows implementation of QLocalSocket.

ac8dae8b5e QLocalServer/Win: Fix race condition in listen().
Suppose a client connects while the QLocalServer is still in the loop
that calls addListener. The connection would SetEvent(eventHandle),
but every call to ConnectNamedPipe would ResetEvent(eventHandle).
Thus, the connection is never detected by the notifier on eventHandle.
  Callers of addListener must check the connection state of every
listener to make sure that no client connected while setting up
listeners.

48f25caac4 Check if socketEngine is set before accessing it.
QTcpServer::addPendingConnection() is protected, so it is possible to
add pending connections from a class derived from QTcpServer. This
derived class can get a QTcpSocket from somewhere else, in which case
d->socketEngine will not be set (or used). Given that it is possible to
add pending connections in this scenario, it would make sense to be able
to retrieve them as well.

294111e25a QHttpSocketEngine: ensure pending EOF triggers a notification
When the remote peer closed the connection, a read notification needs
to always be emitted, otherwise the higher layer does not get the
disconnected signal. From the other side, underlying QAbstractSocket
object could temporarily disable notifications from the engine at
any time. To avoid possible blocking of the socket, take a pending EOF
into account when the read notifications are re-enabled.

To make a bind+connect scenario work properly, disable the read
notifications until a connection is established.

378e26dd14 QUdpSocket: avoid infinite read notifier blocking
There was a small amount of time between the last readDatagram() call
and disabling a read notifier in case the socket had a pending
datagram. If a new datagram arrived in this period, this qualified as
absence of a datagram reader. Do not change the read notifier state
because it is disabled on canReadNotification() entry and always enabled
by the datagram reader.

Thanks to Peter Seiderer, who investigated the same: "Querying
hasPendingDatagrams() for enabling/disabling setReadNotificationEnabled()
is racy (a new datagram could arrive after readDatagam() is called and
before hasPendingDatagrams() is checked). But for unbuffered sockets the
ReadNotification is already disabled before the readReady signal is
emitted and should be re-enabled when calling read() or readDatagram()
from the user."

However, this patch does not completely solve the problem under Windows,
as the socket notifier may emit spurious notifications.

5237b97f26 QAbstractSocket: discard input data when opened only for writing
A buffered TCP socket might be open only for writing purpose. As a
possible use case of the API, this patch avoids accumulation of
unwanted data in the internal read buffer.
