Laszlo Agocs ffa578faf0 Add sRGB capable default framebuffer support for WGL
Not that it changes much since one tyically gets sRGB capable by default
on AMD and NVIDIA at least, but let's handle the QSurfaceFormat flag

Laszlo Agocs f9f9bea370 Compose renderToTexture widgets with sRGB when needed
Just requesting an sRGB texture for a QOpenGLWidget does not lead to
anything useful when it comes to the end result, the content will just get
darkened. For proper operation the target window's default framebuffer
must be sRGB capable and linearization during blending must be enabled.

Cédric Cabessa f971a0d65c Fix proxy when changing only the password
QHttpThreadDelegate doesn't take into account the password to compute the
key of the networkconnection hash. So if only the password for a proxy has
changed, the wrong data gets used for the connection.

This patch simply adds proxy->password() to the key.

Here are the steps to reproduce the bug:
 * Use an authentified proxy and provide the correct username but a wrong
password

```
 QNetworkAccessManager networkAccessManager;
 QNetworkProxy proxy(QNetworkProxy::HttpProxy, PROXY_HOST, PROXY_PORT,
                     "goodusername", "badpassword");
 networkAccessManager.setProxy(proxy);
``

 * As expected, the reply returns ProxyAuthenticationRequiredError

 * Using the same QNetworkAccessManager, setup a new proxy with the
correct credential:

```
 QNetworkProxy proxy(QNetworkProxy::HttpProxy, PROXY_HOST, PROXY_PORT,
                     "goodusername", "goodpassword");
 networkAccessManager.setProxy(proxy);
```

 * The reply still returns ProxyAuthenticationRequiredError

has been used, when supplying the right password.

Thiago Macieira 0f1b6acab7 x86: Add detection of the AES and SHA New Instructions
The AES instructions were first introduced with the Westmere shrink
(22nm) of the Nehalem architecture. The SHA instructions are still
pending on Intel architecture, but is available on AMD family 17h (gcc
argument -march=znver1).

Both features operate on SSE registers, so that's why the MSVC command-
line argument is the SSE2 one and the configure-time tests depend on
features.sse2.

The qmake feature names end in "ni" because "aes" and "sha" are too
simple and could clash with other uses. The QT_COMPILER_SUPPORTS_ macro
doesn't have the "NI" suffix because it has to match the GCC/Clang
predefined macro.

Timur Pocheptsov de225ccdf9 QNetworkSession - register types before connecting slots
QNetworkSession's ctor has a race condition: it 1) connects signals/slots
and also 2) registers meta-types (but after these connects). Our users apparently
have a lot of per-thread QNAMs in multiple threads (and implicitly
many QNetworkSessions on different threads too). From error logs it appears
that while one thread tries to connect signals/slots and evaluates the types
of signal and slot arguments, another thread can register this type.
If the first thread extracted signal argument types, then the second
registered this type, we can end up in a 'type mismatch' error on the first
thread with seemingly the same types in a debug message (something like
"type mismatch A::Some <-> A::Some") - they have the same name, but one
has type() == 0 and another - some non-zero type().

Now we call qRegisterMetaType before connect.

making window state handling work for foreign windows as well, and
also allows us to re-evaluate the state in more places, such as
when moving a window, which may bring it out of maximized state.

The full screen state is tracked by a helper category that doesn't
just rely on the styleFlag, but also on the full screen notifications.
This is needed as macOS will complain if you try to go in or out of
fullscreen while a transition is in effect.

The differentiation between performFoo: and foo: has been removed,
as the latter works in both cases and doesn't rely on the button
being visible/enabled.

These changes fixes many observed quirks in the window state handling
that also resulted in making it hard to write tests that relied on
the fullscreen/maximized operations always working.

Marc Mutz f05d2764b0 QJNIHelpers: unbreak runnables counter
Adding 0 each time will obviously not produce a new identifier each
time...

Also use static initialization for QBasicAtomicInt.

A default-constructed static QBasicAtomicInt at function scope
will be dynamically initialized. It will still be zero-initialized,
but at least GCC adds guard variables for such objects.

When using aggregate initialization, the guard disappears.

Amends 265db5ad9b.

Allan Sandfeld Jensen 925a3c6529 Use native support for fp16 where available
Use F16C or ARM FP16 if available at compile time.

Configure check added because older clang compilers have F16C defines
and flags but not all the intrinsics.

Alexander Volkov bee82432eb xcb: Allow to disable XInput 2 support by setting QT_XCB_NO_XI2 env var
Use of XInput 2 may result in regressions. For example we call
XISelectEvents for each window every time a device plugs/unplugs.
It causes significant delays when there are many native windows.

Marc Mutz 5486882b52 Android: De-duplicate vtables of exported private classes
By making the destructor (usually the first non-inline, non-pure,
virtual function, and therefore the trigger for most compilers to emit
the vtable and type_info structures for the class in that TU)
out-of-line, vtables and, more importantly, type_info structures for
the class are pinned to a single TU. This prevents false-negative
dynamic_cast and catch evaluation.

Since the classes are already exported, users of these classes are
unaffected by the change, and since it's private API, we don't need to
avoid adding code to the out-of-line destructor until Qt 6.

While at it, de-inline also the empty default implementations of
virtual (non-dtor) functions.

Tor Arne Vestbø ee0edf1b0a QWindow: prevent window reparenting into Qt::Desktop windows
Qt::Desktop exists to support QDesktopWidget, which predates the QScreen
API. QWidget internally has checks that prevents you from reparenting a
QWidget into a QDesktopWidget, so we should have the same limitations on
the QWindow level. This allows platform plugins to implement Qt::Desktop
as simple (possibly shared) wrappers around QScreen without having to
allocate native window resources for each desktop window.

Marc Mutz bf2160e72c Clean up QStringLiteral definition
We require lambda support in the compiler since Qt 5.7, so drop
the guard macro.

Apart from MSVC 2013, all our supported compiler also support
char16_t:

- VxWorks uses GCC 4.8, which supports char16_t since 4.5.
- ICC supports char16_t since v12.1; we require v14+.
- ONX uses a GCC which supports char16_t in the compiler,
  but is equipped with a stdlib that does not sport char16_t
  support, which is why we revoke its Q_C_UNICODE_STRINGS in
  qcompilerdetection.h. But we don't need stdlib support, we
  only need the core language feature.
  This is the only platform where this patch actually changes
  something. It removes the, rather unfair, pessimization of
  the platform which could have supported the static-storage-
  duration implementation of QStringLiteral instead of the
  fallback, which uses dynamic memory (QString::fromUtf8()).
- GCC and Clang support char16_t since 4.5 and 3.0, resp.,
  which is far below our minimum compiler requirements in
  effect since Qt 5.7.
- On Windows, MSVC supports char16_t since 2015 only, and we
  still support 2013, but on Windows, wchar_t is the same size
  as char16_t, so instead of u"str" we can fall back to L"str".

So simplify the implementation of QStringLiteral by assuming
that all these feature are present, adding noexcept to the
lambda to make noexcept() queries return true.

This allows us to guarantee:

[ChangeLog][QtCore] QStringLiteral is now guaranteed to be
evaluated at compile-time. The last platform (QNX) to use the
QString::fromUtf8() fallback has been ported to allocate the
string data statically, too.
