And name the main class QList. That's also the one we document.
This gives less porting pain for our users, and a lot less churn
in our API, as we use QList in Qt 5 in 95% of our API.
In addition, it gives more consistent naming with QStringList and
QByteArrayList and disambiguates QList vs QVector(2|3|4)D.

The recomanded use of QMetaType is to construct an object with
QMetaType::fromType. This does not require any registration.
There is still an id() function which will do some registration
for compatibility with Qt5. Also the patch does not really touch
the other extra things that can be registered (data stream operator,
comparison operator, iteratable, ...) and this still uses the previous
system.
This is only the change in QMetaType, other changes to use it in QVariant

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 explanation is in the code comment. Ever since QDBusConnections
began being processed in a separate thread, we were relying on the fact
that the main thread didn't begin processing its event queue until the
second event got posted (the event loop only exits after it has finished
processing all pending events). We had a race between the main thread
starting its processing, at which point it decides which is the last
event it will process, and the QDBusConnectionManager thread posting the
second event.
This is very fragile code, since it depends on the behavior of
QDBusConnectionPrivate (how it stores the signal relays in a hash) and
that of QHash with duplicate keys. This only works because the hash
key between the two connections is the same (it's only dependent on the
method name and interface name). If we ever begin using something that
isn't the same between "control" and "p", then with QHash's randomness,
we'll be racy again.

accordingly. Usage in qdoc, uic and rcc has been left as is

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.
Note: this commit may not be testable (tst_qdbusconnection may fail)

This simplifies the code a little by having a single code path. More
importantly, we no longer need to call the evil function
dbus_connection_send_with_reply_and_block. That function acquires a lock
on the socket transport inside libdbus-1, which means all threads need
to wait until the one call gets unblocked before they can continue.
To do that, this commit reimplements the QDBus::Block part of
QDBusConnectionPrivate::sendWithReply by reusing the existing call to
sendWithReplyAsync() and then doing a blocking-wait with
QDBusPendingCallPrivate::waitForFinished().
By using (Q)DBusPendingCall and the threaded connection approach (next
commit), now we never block on the socket. That also means the code to
call dbus_pending_call_block() is no longer necessary and the
waitForFinished() function itself can be considerably simplified.
As a side-effect of no longer blocking, a number of pre-existing race
conditions that used to be hidden showed up.
Note: this commit deadlocks without the threading (next commits).
