Tor Arne Vestbø 1bc7e9e77b Add QComHelper class for dealing with COM on Windows
Unifies our approach to calling CoInitializeEx and CoUninitialize,
removing a lot of boilerplate in the process, and also fixes a few
bugs where we would incorrectly balance our calls to CoInitializeEx
and CoUninitialize.

The optimistic approach of qfilesystemengine_win.cpp of calling
CoCreateInstance without initializing the COM library explicitly
has been removed, as calling CoInitializeEx should be a noop in
the situation where it's already been loaded.

Volker Hilsheimer 2ffab52a4f Windows: Implement dark mode palette and accent color support
Use the WinRT API to read the basic colors, and construct a usable
palette from those. None of the Windows.UI.ViewManagement.UISettings
APIs returns a full set of usable colors -UIElementColors returns the
old system colors, or useless values. And UISettings::GetColorValue only
gives access to a basic palette, where e.g. the background color is
just black, which doesn't match what Windows itself uses.

However, we know if we want to be dark or light, and can construct a
palette from the basic colors. The most relevant color to read from the
system is the accent color.

In the course of doing that, refactor and clean up the code somewhat to
standardize the handling, and remove hardcoded color values as much as
possible.

This is opt-in: unless the application is started with the QPA darkmode
parameter set to 2, nothing changes.

Morten Johan Sørvig 462b36c3de QIconEngine: move away from virtual_hook usage
Upgrade existing functions to be virtual functions:
  - virtual QString iconName()
  - virtual bool isNull()
  - virtual QPixmap scaledPixmap(...)
  - virtual QList<QSize> availableSizes(...)

Make all of them non-const and remove the const_casts in
the implementation. Keep the default implementation
which calls virtual_hook(), for compatibility.

Note: availableSizes was already virtual, but now loses
the “const”. Port two overrides in the platform themes.

Keep virutal_hook() around for future expansion.

Giuseppe D'Angelo 3e1d03b1ea Port Q_STATIC_ASSERT(_X) to static_assert
There is no reason for keep using our macro now that we have C++17.
The macro itself is left in for the moment being, as well as its
detection logic, because it's needed for C code (not everything
supports C11 yet).  A few more cleanups will arrive in the next few
patches.

Note that this is a mere search/replace; some places were using
double braces to work around the presence of commas in a macro, no
attempt has been done to fix those.

tst_qglobal had just some minor changes to keep testing the macro.

$ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)store\(/$1storeRelaxed\(/g' -i \{\} +

It can be easily improved (e.g. for store check that there are no commas
after the opening parens). The most common offender is QLibrary::load,
and some code using std::atomic directly.

There was actually no reason for these styles being separate
classes in the first place, because both result in the same
appearance for controls on the running version of Windows.
Therefore, the windowsxp style merely appears as a "broken"
version of the windowsvista style, with only minor differences
based on the additional metrics that the vista style provides.
The windowsxp style does NOT, and never did, allow users to get
a Windows XP style appearance on Windows 7 and above (which is
currently Qt's minimum supported platform). Therefore, now that
Qt no longer supports Windows XP, the windowsxp style is unusable.

[ChangeLog][QtWidgets] The windowsxp style is no longer available
as a separate style, because it did not (and cannot) actually
provide an XP-style appearance on currently supported Qt platforms.

Gabriel de Dietrich e1113cae98 QWindowsTheme: Run dedicated SHGetFileInfo() thread
The changes are motivated by the following reasons:

1. SHGetFileInfo() needs to be COM-intialized per thread.
   Microsoft's documentation for CoInitalizeEx() is quite
   unambiguous about this.

2. Following point 1, using a thread from the global thread
   pool means we would taint every such thread with the
   COM-initialization state. This may result in unexpected
   behavior in other parts of the application. Moreover,
   systematic COM-uninitialization can be expensive and
   can't be recommended in this case.

3. Even though the timeout duration is pretty generous, the
   logic is wrong and could lead to serious errors should
   the call to SHGetFileInfo() actually take too long. This
   is because we let the thread run with references to the
   main thread's stack, namely a reference to the file name
   string, and pointers to the result variable and SHFILEINFO
   struct.

Running a dedicated thread allows us to ensure points 1
and 2. Point 3 is ensured by making a local copy of the
file name and using local instances for the info struct
and the result. Then, provided the thread has not been
cancelled, we can copy the info and result values back
into the main thread's stack referenced memory areas.

This also removes all need for QWindowsThreadPoolRunner
which will remain in the code base nonetheless.

Gabriel de Dietrich f9a80e06ac Move Windows font DB and engines to QtFontDatabaseSupport
This allows creating or extending QPA plugins to provide access to QFont
and related types.

It concerns both GDI and DirectWrite engines, as well as the regular and
the freetype based font databases. The qt.qpa.fonts logging category has
been moved together into the QWindowsFontDatabase related files to avoid
depending on the qwindowscontext.h header file. Finally, QwindowsNativeImage
is following pending a future refactor with similar code in qpixmap_win.cpp
and the Windows XP style.

Move the code from QtWidgets/QFileIconEngine into a new class with
virtuals in QtPlatformSupport so that platforms can reuse it.

Prototypically use the class in the Windows and macOS QPA plugins.

Remove QPlatformTheme::fileIconPixmap() and change the type
of the hint QPlatformTheme::IconPixmapSizes from QList<int>
to QList<QSize> so that it fits better with the icon code.

Conflicts:
	configure
5.7 now supports clang on android; but dev re-worked configure

	src/gui/kernel/qevent.h
One side renamed a parameter of a constructor; the other added an
alternate constructor on the next line.  Applied the rename to both
for consistency.

	tests/auto/tools/moc/tst_moc.cpp
Each side added a new test at the end.

	.qmake.conf
Ignored 5.7's change to MODULE_VERSION.

	configure.json
No conflict noticed by git; but changes in 5.7 were needed for the
re-worked configure to accommodate 5.7's stricter handling of C++11.
