In a blocking application, receiving the results of write operations
must be synchronized with the waitFor...() functions. But, clearing
the buffer in another thread can cause the code
localsocket.write(...);
QVERIFY(localsocket.bytesToWrite() > 0);
to fail unexpectedly, if the socket has been disconnected between
the calls.
So, defer resetting the buffer until checkForWrite() is called.

There were several issues with the socket state checking when the pipe
reader is not running:
- the number of object handles in the WaitForMultipleObjectsEx()
call might have been zero;
- a call to the waitForDisconnected(-1) might have hung;
- we did not perform a loop iteration for the waitFor...(0) calls,
so disconnect detection was unreliable.
These issues are related to the same code, so they don't seem to be
addressable separately.

In the case where we have pending data to write, calling flush() here

the following code to unexpectedly fail on Windows

According to the documentation, calling abort() should immediately
reset the socket to its initial state. This includes:
- closing the file descriptor;
- closing the QLocalSocket as an I/O device;
- canceling a pending outgoing connection, if it exist;
- reseting 'serverName' string.
So, adding a call to close() resets the state entirely.

When a foreign event loop that does not enter an alertable wait state
is running (which is also the case when a native dialog window is
modal), pipe handlers would freeze temporarily due to their APC
callbacks not being invoked.
We address this problem by moving the I/O callbacks to the Windows
thread pool, and only posting completion events to the main loop
from there. That makes the actual I/O completely independent from
any main loop, while the signal delivery works also with foreign
loops (because Qt event delivery uses Windows messages, which foreign
loops typically handle correctly).
As a nice side effect, performance (and in particular scalability)
is improved.
Several other approaches have been tried:
1) Using QWinEventNotifier was about a quarter slower and scaled much
worse. Additionally, it also required a rather egregious hack to
handle the (pathological) case of a single thread talking to both
ends of a QLocalSocket synchronously.
2) Queuing APCs from the thread pool to the main thread and also
posting wake-up events to its event loop, and handling I/O on the
main thread; this performed roughly like this solution, but scaled
half as well, and the separate wake-up path was still deemed hacky.
3) Only posting wake-up events to the main thread from the thread pool,
and still handling I/O on the main thread; this still performed
comparably to 2), and the pathological case was not handled at all.
4) Using this approach for reads and that of 3) for writes was slightly
faster with big amounts of data, but scaled slightly worse, and the
diverging implementations were deemed not desirable.
