967372c975 sanitize qt rpath handling, in particular on mac
the addition of qt's rpath belongs into qt.prf - even on mac.
so consolidate the two implementations.
as a nice "side effect", we get relative rpaths also on linux.
another "side effect" is that we don't unnecessarily add the qt rpath to
qt modules also on linux.

the qt rpath addition mechanism should not be responsible for setting
the policy who gets a relative rpath, so move the logic to higher-level
callers.

f58e95f098 remove some mac multiarch vestiges
ppc/ppc64 and 32-bit x86 have been dead for a while.

consequently, the legacy macx-g++-64 spec was most probably not used.

which in turn meant that NATIVE_64_ARCH was never set (in particular on
windows hosts ...), which means that the android ndk host auto-detection
was effectively broken.

the arch code in mac/default_post.prf was also never triggered, so nuke
it as well.

f8cc0164db Android: Always queue calls from Qt to Android.
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.

e15e5b1d37 Bypass connectSignal() for receiving the NameOwnerChanged signal
This is an optimization but is required. Instead of going through the
entire (dis)connectSignal() stack to add/remove matching rules for the
NameOwnerChanged bus signal and call into our serviceOwnerChangedNoLock
slot, create a static hook that will match the signal and simply add/
remove the rules as needed.

The required part is that this avoids a recursion into connectSignal().
The next commit will move this code to the QtDBus manager thread and we
won't be able to call connectSignal() from there (it would create a
deadlock).

186d881440 Remove the event callbacks in QDBusConnectionPrivate
They were used when we called the libdbus-1 message-sending functions
from any thread, which meant that the callbacks could be triggered on
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.

[*] exception: the callbacks are first called in the thread that invoked
QDBusConnection::connectTo{Bus,Peer}, before we've done the
moveToThread.

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.

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)

939b7c630d Implement the blocking QtDBus call in terms of the non-blocking one
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).

The cost of connecting a signal may be a bit high, but it's comparable
to looking up the invokable method. However, QMetaMethod::invoke has a
higher cost than a signal-slot emission -- though in any case they're
both dwarfed by the cost of allocating the QMetaCallEvent and the
posting of it.

This is much more readable, though.

f3fd7b3d96 winrt: Move EGL surface to window.
Fixes GPU memory leak when window is created/deleted dynamically and
repeatedly. EGL context used to own EGL surface, but the context
outlives the surface if window is created/deleted dynamically. The
EGL surface is now owned by the window and destroyed with it.

fe1ba87961 Fix QMAKE_CXX/CROSS_COMPILE verification with ccache
The use of ccache leads to QMAKE_CXX definitions of the form:

    QMAKE_CXX = $${CCACHE} $${CROSS_COMPILE}g++

The previous test required QMAKE_CXX to be a single valid (absolute or
QMAKE_PATH_ENV-relative) path to an existing file, which was not
compatible with definitions of QMAKE_CXX like the one above.

Fix this by using only the first value in QMAKE_CXX, which usually
points to the compiler executable, or to the ccache executable in the
above case.

65efeb6f9d QImage: Inline constScanLine call in pixel()
Calling constScanLine() is an extra function call, just for doing
"data + y * width". Also, we are checking d again, even though we
already know it's there.

The constScanLine() call is responsible for up to 15% of the total
CPU time spent in pixel().

6774157d8b WinRT: Deployqt version/copyright information to dlls
If no_generated_target_info is not set, VERSION is set, and
there is no .rc file that belongs to the project, qmake creates a
.rc file that contains information about the target's version
and copyright, for example. This resource handling is also
supported by WinRT and we can add this information to the target.

On Windows Phone, winresrc.h (which is needed for resource
handling) is not available though. When trying to add a .rc file
to a project in Visual Studio, it also complains about winres.h
not being available. Instead of hacking around the issue, we
just should not support this behavior on Windows Phone.

6de8c0aa09 Add a qt_version_tag symbol to QtCore that uses ELF versions
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.

72ba0079c3 Add a linker version script to Qt libraries
This linker script is only enabled for systems with GCC or GCC-like
compilers, though technically it should work on the BSDs too (will
enable after testing). For regular modules, this declares one ELF
version "Qt_5" and places all QtCore symbols inside, then it declares
unused ELF versions "Qt_5.x" for each older minor release. For modules
declared "internal_module", all symbols are placed in version
Qt_5_PRIVATE_API.

The big advantage of an ELF version is that, when we do Qt 6, both
versions of QtCore could be loaded in memory without conflicts and all
symbols would be resolved to the correct library. No module can talk to
both at the same time, but this avoids mistakes of loading them
indirectly by plugins.

The extra Qt_5.x versions will be used in the next commit.
