cf63b0e1df qsimd: add support for new x86 CPU features
This adds detection for: VAES, GFNI, AVX512VBMI2, AVX512VNNI,
AVX512BITALG, AVX512VPOPCNTDQ, AVX512_4NNIW, AVX512_4FMAPS. These
features were found in the "Intel® Architecture Instruction Set
Extensions and Future Features" manual, revision 30. This commit also
adds support for RDPID (already in the main manual) and the Control-flow
Enforcement Technology, which appears in a separate Intel paper.

This new support was done by adding a new generator script so we don't
have to maintain two tables in sync, one in qsimd.cpp with the feature
names, and the other in qsimd_p.h.

Since we now need a lot more bits, it's no longer worth keeping the two
halves of the qt_cpu_features variable mostly similar to the main two
CPUID results. This commit goes back to keeping things in order, like we
used to prior to commit 6a8251a89b (Qt 5.6)

At the time of this commit, GCC 8 has macros for AVX512VPOPCNTDQ,
AVX512_4NNIW, AVX512_4FMAPS, AVX512VBMI2 and GFNI.

43ea15d01c macOS + FreeType: Properly distinguish memory fonts from file fonts
In recent macOS versions the descriptor created from the function
CTFontManagerCreateFontDescriptorFromData() will contain the
NSCTFontFileURLAttribute with a value such as:

 file://iNmEmOrYcGfOnT_0x101d3c3a0#postscript-name=New

Which means we can't use the presence of the kCTFontURLAttribute to
determine that we're dealing with a file font. Instead we check for
our custom kQtFontDataAttribute first, which is only set for memory
fonts.

fc356a1992 QNX: Move screen event retrieval to the GUI thread
Instead of retrieving screen events itself, the screen event thread
now turns screen event notification into a Qt signal.  In response to
the signal, the GUI thread processes screen events.  Eliminates the
need to coordinate access to a screen event queue.  Also prepares the
way for getting rid of the screen event thread.  This could be done if
the QNX event dispatcher were switched from poll to MsgReceive
(dispatch).

93e0ff037e QJsonDocument: Validate also zero-length objects
The added test case is the binary JSON equivalent of

    {"a":{"š":null}}

with two modifications. First, the length of the string "š" has been corrupted
to 0xFFFFFF00. Second and more import, the Base::size field of the inner object
has been reset to 0.

On its own the first modification would normally trigger a validation error.
However, due to the second modification the Value::usedStorage for the inner
object evaluates to 0, completely disabling all further validation of the
object's contents.

Attempting to convert this binary JSON into standard JSON will lead to the JSON
writer trying to construct a QString of length 0xFFFFFF00.

Fixed by validating also objects with usedStorage == 0.

10b3286313 qpa: improve API to support DnDs from other processes
... instead of using a hack of directly accessing QGuiApplication
members.

The current QPA API was bad for two reasons:

1) It expects platform plugin authors to know about
internals of Qt Gui, particularly that QGuiApplication
uses QGuiApplication::{mouseButtons,keyboardModifiers}
to construct QDragMoveEvent and QDropEvent events. Which
results in the second reason why this is bad.

2) Platform plugins should not directly access member
variables of QGuiApplication, just to make sure that
QDragMoveEvent and QDropEvent events contain correct state.
Platform plugins should instead use QWindowSystemInterface
to communicate with Qt Gui (which is also the solution here).

The solution is to extend QWindowSystemInterface::handle{Drag,Drop}
to require mouse/keyboard state. We already do this for
some of the other methods, so it is nothing extraordinary.
This type of interface is also _required_ to support
drag-n-drops from other processes. We can't use
QGuiApplication::{mouseButtons,keyboardModifiers} when the
drag originates from another process, instead we need to
query mouse/keyboard state from the system.

This patch fixes drag-n-drops from others processes on XCB
platform plugin.

e28ae083d2 macOS: Fix stretch of condensed fonts with NoFontMerging
When showing a condensed font with AnyStretch, we should
not apply any stretch to the font (and if a stretch is
requested, we should calculate the actual stretch based
on how much the font is already stretched or condensed).

This usually works as expected, however, when using
QFont::NoFontMerging as the style strategy, we would
scale the glyph advances by the stretch of the font
since the calculated stretch of the font engine would
be overwritten by the actual stretch. In the case where
we use font merging, this would be done for the multi
engine, so we would not get the same issue, since the
text engine gets the stretch from the actual font engine
and this still has the original, calculated stretch
set.

Note on the test: We can't use testString() for this,
since it contains a space, and the test font does not
have a glyph for this, so we will end up merging a
different font for the space, giving us a slightly
different advance.

[ChangeLog][QtGui][macOS] Fixed display of condensed fonts
when NoFontMerging is in use.

While this parent window won't give us much information from

the main reason we will need this is to check for modality blockage.
Indeed, QApplicationPrivate::tryModalHelper() only cares about the
widget's window since modality blockage is decided at the window level.

the first thought to fix this was to just use $$lower($$TARGET), but
that breaks for testlib (QtTest). while the config file name isn't
public api, it's included by a public header, so changing it is risky.

so instead stay with the original pattern, but make it explicitly

6a39e49a6c Upgrade double-conversion to v3.0.0
This fixes their issue #41, a potential undefined behavior.

We preserve the locally added "__ghs" clause as well as the _M_ARM_FP
clause necessary for winrt in utils.h.

[ChangeLog][Third-Party Code] double-conversion got updated to upstream
version 3.0.0.

fa854f214a Unix print dialog: Properly initialize duplex
In case the user has explicitly selected a value for the
duplex mode in the print dialog before, select this one when
another printer is selected and the newly selected printer
supports it.

Otherwise, always set to the default value of the respective
device that was selected.

This way, default values that the user (or admin) has set for
a CUPS printer (or printer instance) are honored, but an explicit
user choice made in the dialog takes precedence.

Previously, the duplex values was always reset to "None"
every time the printer was changed.

3e001feb4d If the page size is not valid on the new printer, set a custom size
When the page size was not valid on the new printer, it would end up
having the wrong page size name on the new printer. What should happen
in this case is that it should set the originally set page size as a
custom page size on the printer instead.

So that Qt responds correctly when window managers make geometry
changes.

Note: Older versions of screen, such as the screen from the QNX 6.6.0
4036 patch, don't produce SIZE/POSITION property events.
