Passing QDBusUnixFileDescriptors over peer-to-peer connections currently
does not work, because QDBusConnectionPrivate::setPeer() does not set
this->capabilities (unlike QDBusConnectionPrivate::setConnection()
which is executed for bus connections).
Keep track of whether the connection already has been authenticated, and
once the connection does get authenticated, update this->capabilities.
Note that sending a message directly after connecting (before any
message has been received from the peer) might still fail if the message
contains a QDBusUnixFileDescriptor.

This does the analog of 46f407126e for the
methods we care about (signals, slots, Q_INVOKABLEs). In addition to the
actual QMetaType, we store an array with offsets so that we later can do
a mapping from methodIndex to metatype.
The newly added QMetaMethod::{return,parameter}MetaType methods can then
be used to retrieve the metatypes.
This does however require that all involved types are complete. This is
unfortunately not a feasible requirement. Thus, we only populate the
metatype array on a best effort basis. For any incomplete type, we store
QMetaType::Unknown. Then, when accessing the metatype, we fall back to
the old string based code base if it's Unknown.
Squashes "moc: support incomplete types" and "Fix compile failures

This allows us to get rid of two Q_GLOBAL_STATIC in QtDBus, which means
fewer opportunities for screwing up the order of destruction. And since
QDBusConnectionManager now ensures that the types are initialized, we
don't need to re-initialize them everywhere.
The Q_GLOBAL_STATIC for QDBusConnectionManager ensures the proper
thread-safe locking, so we don't need to lock for every type that we're
trying to register. This should make things faster.
But as a side-effect, trying to register a D-Bus metatype will cause the

The Microsoft documentation says _beginthreadex and _endthreadex are
used to initialize the C/C++ runtime and are necessary when linking to
libcmt(d).lib (that is, when using the -MT or -MTd options). For regular
builds linking against the .dll runtime, there should be no impact.
Inspection of the CRT source code which gets installed with Visual
Studio or Windows SDK proves that.
It's preferable to use CreateThread directly as _endthreadex will try to
call FreeLibraryAndExitThread, which can cause a deadlock if we try to
wait for the thread to exit from a global destructor.
For -MT builds, since there can be no DLLs, it's not a problem to
continue to use _beginthreadex and follow Microsoft's recommendation.

To retain a bit compatibility with applications developed in the last 9
years that expect that QDBusConnections won't process their events until
the event loop runs, we now suspend the handling of incoming messages
in the two default buses (and only in them) and resume when the event
loop starts. This is required because the new threaded QtDBus would
otherwise process incoming messages that the application didn't expect
it to.
For example, if the application first acquires names on the bus and only
after that registers objects with QtDBus, there's a small window in
which the name is acquired and visible to other applications, but no
objects are registered yet. Calls to those objects may be received,
would then be processed in the QDBusConnectionManager thread and fail.
The work around is to disable the actual handling of method calls and
signals in QDBusConnectionPrivate::handleMessage. Instead, those
messages are queued until later.
Due to the way that libdbus-1 works, outgoing method calls that are
waiting for replies are not affected, since their processing does not
happen in handleMessage().
[ChangeLog][Important Behavior Changes] QtDBus now uses threads to
implement processing of incoming and outgoing messages. This solves a
number of thread safety issues and fixes an architectural problem that
would cause all processing to stop if a particular thread (usually the
main thread) were blocked in any operation. On the flip side, application
developers need to know that modifications to a QDBusConnection may be
visible immediately on the connection, so they should be done in an
order that won't allow for incomplete states to be observed (for
example, first register all objects, then acquire service names).

The two global statics for the session and system buses aren't necessary
if they can't outlive the global static for QDBusConnectionManager
anyway. So merge them there. The extra mutex is necessary because the
QDBusConnection::connectToBus function will lock the regular mutex.
This solves a potential memory leak at exit as a side-effect. Before
this change, the session and system QDBusConnection object got destroyed
in the main thread during global destruction, so it had to post an event
to the QDBusConnectionManager thread to finish the destruction of the
private. However, QCoreApplication is already gone by this point, so the
QEvent::DeferredDelete event never got delivered.
After this commit, there's no global static to destroy the
QDBusConnection (there is no QDBusConnection holding a reference), so
the object gets destroyed in QDBusConnectionManager::run()'s cleanup
code.

Each application will have one thread dedicated for this, for all
QDBusConnections. I wouldn't mind sharing such a thread with other uses
in Qt, provided none of them ever block (the QProcessManager thread
comes to mind, but it's going away soon).
The cost associated with this change in this commit is so far rather
minimal. All incoming D-Bus calls need to be handled after an event is
posted anyway, to avoid deadlocking on reentering libdbus-1 functions
that acquire locks still held. The cost is the one more thread running
and the cost of synchronizing them when an event is posted.
The benefits far outweigh that cost: no longer will we have problems of
QtDBus failing to run if the main system or session connections are used
before QCoreApplication is run. Moreover, events can be received and
handled in aux threads even if the main thread is blocked on some
operation.
