5b5e8f78fe NSMenuItem/NSMenu - set the submenu properly
... in case the submenu is set from a slot, attached to the aboutToShow()
signal. Normally, with a 'statically' pre-populated menu, we set 'submenu'
property on a menu item from 'updateItem' callback in our menu delegate.
After that, AppKit calls our delegate's willOpen call back and this is
where we emit 'aboutToShow'. Unfortunately, if an application tries to
create a nested menu 'dynamically' at this point, it never becomes 'submenu'
of the item, since 'updateItem' was already handled at this point.

We catch this case in QCocoaMenuItem and call setAttachedItem if needed.

b6ded193ee QHighDpi::fromNativePixels: use correct screen
Calls like
	QHighDpi::fromNativePixels(point, window)

would return device independent coordinates outside any
screen in cases where the window is spanning multiple
screens and the native point was not on the main screen.

Correct this by looking up the correct screen and use
its scale factor and origin when scaling coordinates.

0f3f143f6d Fix window shortcuts when a completer popup has focus
The completer popup has focus, making QShortcut direct to it's window
rather than to the window the completer belongs to. As QShortcut handles
the case for Tool windows that have a parent, but doens't do the same
for popups. And they shouldn't be treated the same way, as a context
menu popup for a e.g. text edit should in fact block the text edit's
shortcuts while open.

However, the completer popup is special, in that it explicitly makes the
widget completes for its focusProxy, which is what we can use to fix
this issue.

859eb2467d Add qmake config for controlling LTCG behavior for static libs
Static libraries may get installed and used by other builds, which may
be done with a different version or build of the compiler. So this
commit introduces two new flags:
 - no-static-ltcg: disables LTCG completely for static libraries
 - fat-static-lto: forces static libraries to produce fat LTO objects

fat-static-lto is useful for Linux distributions, since installed static
libraries should not carry LTO information, but that information is
useful during Qt's own build. This feature should be used alongside some
compiler-specific method of removing the LTO information from the
static libraries prior to installation, so only the regular part
remains.

For current GCC versions, this command suffices:
  strip -R '.gnu.lto*' -R '.gnu.debuglto*' libname.a

Otherwise, distributions can use "no-static-ltcg" to disable it
completely.

cbdc9a7786 RCC: Change the default compression to Zlib
Codebases using QResource::isCompressed() and assuming it is Zlib break
if zstd is enabled. So change the default back to Zlib until Qt 6.0.

[ChangeLog][Important Behavior Changes] RCC's default compression
algorithm was changed back to Zlib, as it was in all previous releases
until 5.13.0. The default will remain Zlib for all Qt 5.x releases but
will change in Qt 6.0. To activate Zstd compression for your resources,
either pass the --compress-algo=zstd option to the rcc tool or add the
XML attribute compression-algorithm="zstd" to the <file> tags in the
.qrc file.

cdfe8c76af checkOcspResponse - remove unneeded locking
and also plain wrong comments: since we don't set verification callback
on a store - we don't have to lock (our q_X509Callback never gets called).
This change should simplify the merge with change I have in 5.12 (where
I completely got rid of locking). Since I don't care about exact errors
found (relying on the fact it's the same chain of certs we check in
SSL_connect/SSL_accept), for now we don't try to extract them from
OCSP_basic_verify. In fufure, if these chains are different, we
can create a temporary store (see how it's done in 'verify', for example)
and set a VF callback on this store.

82da8306bc Deal with multi-display scenarios when positioning menu popups
This is to support rare setups involving an X11 server with multiple
independent displays ("zaphod heads" on which the DISPLAY env var
is different), possibly with multiple outputs forming a virtual desktop
on each display.

QMenu::popup() has been assuming that it should show on the screen where
the mouse cursor is.  That's good most of the time; but with multiple
independent screens, QGuiApplication::screenAt(pos) cannot tell us which
screen to use (it's ambiguous), but rather will choose the first screen
that _could_ contain that position (as documented).  In the example in
QTBUG-76162, the QMenu has been constructed with a QDesktopScreenWidget
as its parent specifically for the purpose of telling it which screen to
pop up on; so we need to respect that.  But QWidgetPrivate::init() sets
the QObject::parent() to null (because the widget isn't actually shown
as a child of the QDesktopScreenWidget), and QWidgetPrivate::create_sys()
sets initialScreenIndex back to -1 to provide freedom to change the
screen later; so QMenu has to remember the screen index for itself.

QMenuBarPrivate::popupAction() searches the siblings of the screen on
which the menubar is claiming to be (rather than all screens on all
displays), to find the screen containing the point at the middle of the
bottom edge of the clicked menubar item.  It then sets initialScreenIndex
so that QMenu::popup() will respect it rather than trying to decide for
itself.

73a19a3a10 Stabilize tst_qsplitter
This is the worst fix ever, adding one more qWait. The test has been
updated in the 5.13 branch, so there a different fix will be needed. For
now this is in line with the rest of the code.
This test is currently one of the worst offenders when it comes to flaky
tests.

fe6e54fb1f TLS socket: make verification callback lock-free (OpenSSL)
When our QSslSocketBackendPrivate (OpenSSL backend) was developed,
the ancient versions of OpenSSL did not have an API needed to pass
an application-specific data into verification callback. Thus the
developers resorted to the use of global variables (a list with errors)
and locks. Some of our auto-tests use QNAM and in-process server.
Whenever the client (essentially qhttpthreadeddelegate) and the server
live in different threads, any use of 'https' is dead-lock prone,
which recent events demonstrated and which were previously observed
but not understood properly (rare occasions, not always easy to
reproduce). Now we fix this for good by removing locking.

There are two places (in 5.12) where these locks are needed:

1. Before calling SSL_connect/SSL_accept (handshake) - here
   we reuse the same trick we do in PSK callback ('SSL' has
   an external data set, and it's 'this', meaning an object
   of type QSslSocketBackendPrivate).

2. The static member function 'verify', here we do not have
   'SSL', but we have our temporary 'X509_STORE', to which
   we can directly attach an external data - a pointer to
   a vector to collect verification errors.

Note, this change assumes that OpenSSL Qt is build/linked
against is at least of version 1.0.1 - we set external data
on SSL unconditionally (no version checks).
