24f770ba24 Add qtdbusglobal.h and qtdbusglobal_p.h
The new modular configuration system requires one global
header per module, that is included by all other files in
this module.

QtDBus already had such a header, but its name (qdbusmacros.h) was
not in line with what's being used in all other modules. So
add a qtdbusglobal.h header, and turn qdbusmacros.h into a a forwarding
header to that new global header file.

1f6fa1f37a Suspend processing of some messages in the default busses by default
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).

68964b1023 Merge two Q_GLOBAL_STATICS into another and solve memory leak
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.

ea01d7784a And move the creation of connections to the thread
Now we know that all timers and socket notifiers get created only in the
QDBusConnectionManager thread.

Incidentally, this reduced code duplication.

c2049f67e4 Use a dedicated thread for handling incoming libdbus-1 events
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)

83a5694dc2 Update copyright headers
Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

Outdated header.LGPL removed (use header.LGPL21 instead)

Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)

Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination
