QtWebEngine::initialize happens after QGuiApplication instantiation,
so it is too late to simply set the application attribute.
In that scenario, we don't want to override the shared context and risk
a double free when both QGuiApplication and our cleanup handler try
to delete it.

This is done on initialization of the Web Engine as this should
happen before any contexts and Direct 3D devices are created.

It makes D3D9 create a device with the D3DCREATE_MULTITHREADED
flag and makes D3D11 enable multithread protection using the
ID3D10Multithread interface.

Depends on the appropriate counterpart in QtANGLE.

Manually import qt_(set_)gl_global_share_context from QtGui
instead.

The binary compatibility of those symbols should be maintained
in QtGui, allowing us to avoid depending on private API.

This means that widgets application now need to setup the GL context
sharing as well. QWebEngineWidgets::initialize() must be called,
which has the same effect as QWebEngine::initialize().
The QtWebEngineWidgets now depends on the QtWebEngine module to make
this happen.

Since QOpenGLWidget is only available in Qt 5.3, this patch also
disables the webenginewidgets module completely when building using
Qt 5.2.

We now require the user to use QWebEngine::initialize() in main (preferably) and
print out an error message if this wasn't set up accordingly. This limits the use
of private scene graph API to inside QWebEngine and offers public API for users
of the API.

This only move files without adjusting any paths.

This moves:
- lib/quick -> src/webengine/api (API files)
  lib/quick -> src/webengine (other files)
  This contains the main QtWebEngine module library since

- lib/widgets -> src/webenginewidgets
  Also rename this directory to match its module name and rename Api to api.
- lib -> src/core
- process -> src/process
- resources -> src/core/resources

The build directory is spread as follow:
- build/build.pro -> src/core/gyp_run.pro
- build/qmake_extras/* -> src/core/ (for the host and target .pro files)
- build/qmake -> tools/qmake

Make the WebEngine QtQuick plubin library a library only that fetches
the API privatly from the official module.

This will allow an experimental plugin library to also have access to
the API classes, which it currently can't since the plugins aren't
deployed the same way as module to <prefix>/lib.

The module currently only export classes privately but the plan is
to make this library the official linking point of entry for
applications along with the Qt5WebEngineWidgets module.
The WebEngineCore library could eventyally be merged into this module
library if we can get gyp to play well with qmake.

This is the first step to making proper Qt Modules out of QtWebEngine.
The Widgets integration becomes a proper C++ Qt Module while we make
the QtQuick side a QML plugin for now (could probably be promoted if
the need arises).

Code-wise, this means the introduction of a WebContentsAdapterClient
interface that is subclassed by the private implementation of our API
classes for delegation of things that are UI specific. Functionality
from WebContents and the like is exposed via the WebContentsAdapter.

Fix the gyp generator to allow including the moc file directly
in qwebcontentsview.cpp to be able to use Q_PRIVATE_SLOT
instead of having the private object deriving from QObject.

This also removes the use of MOCABLE_SOURCES whose entries were
added to 'sources' without moc being run on them first.

- Rename NativeViewQt to RenderWidgetHostViewQtDelegate to keep the
  context obvious.
- Use an interface to handle the parenting instead of the
  NativeViewContainerQt mechanism that was needed with the Shell.

This layers things properly to be able to implement the UI in the
example application instead of directly in shell_qt.cpp.

This is still using global variables to allow the Shell platform
code to do callbacks to the API classes. This should go away once
we properly implemented a WebContentsDelegate.
