It seems this example never worked as expected.
It has a 'multiple' option which should show extra
windows with rendering taking place in different
thread, however although render is moved to other thread
render() function was never called in that thread.
Fix following things:
* make rendering in other thread
* stop requestUpdate if nothing is exposed
* add timer so animation works at the same speed despite
of number of windows (renderer B renders two windows)
* wait for render to finish before triggering requestUdpate
* remove mutex where not needed
Pick-to: 5.15

Use M_PI (and friends), where possible, in favor of hand-coded
approximations of various (in)accuracies. Where that's not available
(e.g. fragment shaders), use the same value that qmath.h uses for
M_PI, for consistency. Replaced math.h with qmath.h in places that
defined a fall-back in case math.h omits it (it's not in the C++
standard, although M_PI is in POSIX); or removed this entirely where
it wasn't used.
Reworked some code to reduce the amount of arithmetic needed, in the
process; e.g. pulling common factors out of loops. Revised an
example's doc to not waste time talking about using a six-sig-fig
value for pi (which we no longer do) - it really wasn't relevant, or
anything to be proud of; nor did the doc mention its later use.

Platforms like eglfs allow a single window per screen. Thus the behavior of
--multiple is not suitable since it tries to open multiple windows on the
primary screen. Instead, introduce --multiscreen.
Add also --timeout to quit the app after 10 seconds. This is essential on
platforms that do not have windows with decorations that can be used to
close windows.
With eglfs' kms/drm hooks, starting with --multiscreen will now show a
rotating logo on all connected displays, with some random background color.

Change them to use QOpenGLWidget and QOpenGLTexture.
Advocate also the usage of VBOs.
Hopeless examples, that rely on the fixed pipeline and will
not compile or work in ES and dynamic builds, are moved to
a "legacy" directory. The documentation pages for these are
removed. This long due change avoids the confusion newcomers
experience when trying to get started with Qt 5 and OpenGL.
hellowindow's behavior is changed to open a single window only
by default. The old default behavior, that opened three windows
on platforms that supported both MultipleWindows & ThreadedOpenGL,
can be requested by passing --multiple. --single is removed since it
is the default now. This plays much nicer with drivers that have
issues with threading.
In addition, say hello to hellogl2.
This is the old hellogl example updated to use QOpenGLWidget and
OpenGL 2. It also has a mainwindow with multiple (un)dockable widgets
containing the OpenGL widgets. This helps testing the behavior when
the top-level of the QOpenGLWidget changes and provides a very
important example of how to do proper resource management in this case.
(must use aboutToBeDestroyed() of the context, since the context goes
away and is replaced by a new one on every dock/undock)
As a bonus, the logo is now real 3D, no more orthographic nonsense.
Launch with --multisample to request 4x MSAA.
Launch with --coreprofile to request 3.2 Core. In this particular example
the shaders are present in both versions and there is a VAO so the application
is functional with core profile contexts.

This introduces the ability to indirectly invoke all common GL1-GLES2
functions via QOpenGLFunctions. The GL1 functions are not yet resolved,
since this would not work anyway when linking to an OpenGL implementation
directly. However this may change later but that will be a completely
internal change without affecting any public APIs.
Also migrate some of the opengl examples to use QOpenGLFunctions for
everything. Once dynamic GL loading becomes available on some platforms,
these examples should continue to function without any changes since they
do not anymore invoke any OpenGL functions directly.

windowTitle, windowModality, windowIcon and so on are named that way
to be similar to the ones in QWidget. However QQuickWindow inherits
all of the declared properties, and we would like to have shorter
property names in QML. If you are working with a Window then it's
obvious the title property is the window title. Unfortunately,
there must be patches in many other modules which depend on this one.
In order to avoid the need to merge them all at the same time,
there is also patch https://codereview.qt-project.org/#change,39001
which temporarily adds backwards-compatible accessors, which can be
removed after the other modules are able to build without them.
We should not rename windowState to state, because in QML, state
usually drives the state machine for animation transitions etc.
(although QWindow is not an Item, a user might get confused about it).

The main reasons for doing this are:
1. _qpa.h end up in the master QtGui include file. QtGui is meant for
userland applications. qpa code is neither binary nor source compatible.
Inadvertant use of QPA api makes the user code binary-incompatible.
2. syncqt creates forwarding headers for non-private header files. This
gives people the impression that this is public API.
As discussed on the mailing list, even though QPA api is internal and subject
to change, it needs to treated differently from private headers since they
will be used by in-qtbase and out-of-qtbase plugins.
This commit does the following:
1. The _qpa in QPA header files is dropped.
2. syncqt now treats any file with qplatform prefix as a special file and
moves it to qpa/ directory. The recommended way of using QPA API in plugins
is: #include <qpa/qplatformfoo.h>. This allows the user include QPA API
from multiple modules (for example, qplatformfoo might be in QtPrintSupport)
3. The user needs to explicitly add QT += <module>-private to get access to
the qpa api.
4. Creates compat headers for the olden style qplatformfoo_qpa.h and QPlatformFoo
includes.
This commit does not change the cpp filenames. This requires a more careful
merging of existing non qpa cpp files and existing cpp files on a case by
case basis. This can be done at anytime.
The following files are not renamed as part of this changed but will be fixed
as part of a future change:
src/gui/kernel/qgenericpluginfactory_qpa.h
src/gui/kernel/qgenericplugin_qpa.h
src/gui/kernel/qwindowsysteminterface_qpa.h

includes were renamed using script
