According to MSDN, the zero value of ICONDIRENTRY bHeight and bWidth
fields mean a maximum icon size 256 pixels. So QtIcoHandler::option()
should return 256 instead of 0 pixels for such icons. Also there is
fixed wrong seek offset at the second call on this method.

Calling runOnUiThread() only queues calls that comes from a different
thread then the UI thread. The problem with the current solution is that
we can't promise or rely on the calls being delivered in the same order
they were called. Another consequence of the old behavior is that we
potentially cause long lasting synchronization points, which can cause
the application to become unresponsive or in worst case result in a
deadlock. With this change all calls to runAction() will be queued on
Android's main message queue (aka the UI thread) and return immediately.

They were used when we called the libdbus-1 message-sending functions

any thread. Since we moved the message-sending to one thread only (the
manager's thread), there's no need for the event fallback anymore.
Since they're also always[*] running on an aux thread, there's no point
in checking for the presence of a QCoreApplication instance anymore. I
don't think there has been a need for this for many years, as the event
dispatcher has been decoupled from QCoreApplication for a long time.

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.
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).

This symbol will exist with different ELF versions, allowing us to know
which version of Qt a given library or application was linked
against. When this symbol gets used, automatic packaging tools will
extract the dependency. The trick here is that the application uses
qt_version_tag without knowing which version is current, but the linker
resolves it to the current version and records that.
For example, if this were used with Qt 5.5, RPM's find-requires on an
application using QtCore would print:
libQt5Core.so.5()(64bit)
libQt5Core.so.5(Qt_5.5)(64bit)
libQt5Core.so.5(Qt_5)(64bit)
Whereas find-provides on QtCore would print:
libQt5Core.so.5()(64bit)
libQt5Core.so.5(libQt5Core.so.5)(64bit)
libQt5Core.so.5(Qt_5.0)(64bit)
libQt5Core.so.5(Qt_5.1)(64bit)
libQt5Core.so.5(Qt_5.2)(64bit)
libQt5Core.so.5(Qt_5.3)(64bit)
libQt5Core.so.5(Qt_5.4)(64bit)
libQt5Core.so.5(Qt_5.5)(64bit)
libQt5Core.so.5(Qt_5)(64bit)
Therefore, automatic dependency resolution would have the information it
needs to conclude that the application requires Qt >= 5.5.
