Takes advantage of Linux's and Android's support for abstract namespace
when binding sockets, which is independent of the filesystem (see man
entry for unix domain sockets).
To make QLocalServer and QLocalSocket use an abstract socket address,
one needs to set the socket options to QLocalServer::AbstractNamespaceOption.

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.

To read data from a named pipe, QWindowsPipeReader uses the ReadFileEx()
function which runs asynchronously. When reading is completed and the
thread is in an alertable wait state, the notified() callback is called
by the system, reporting a completion status of that operation. Then the
callback queues a readyRead signal and starts a new sequence. The latter
is skipped if the pipe is broken or the read buffer is full.
Thus, if an application does not run the event loop, the next call to
QWindowsPipeReader::waitForReadyRead() should emit the queued signal
and report true to the caller even if no new read operation was started.
