std::vector is all that the Array original author dreamed about,
and more: never shrinks capacity, non CoWed, ...

Appart from append(), the Array API was modeled after std::vector
(size_t size_type, etc) already, so the port to std::vector is
minimal. The only change besides append() -> push_back() was not
assuming const_iterator being const T*.

Remove now-unused Array.

Laszlo Agocs 101a6bda45 Fix GL_VERSION parsing when using WGL
Unlike other platforms and the EGL path, this one tries to parse
GL_VERSION on its own. Unfortunately it breaks for certain version
strings: we cannot assume more than major.minor in the beginning
and so looking for a second dot is wrong.

For example, "2.1 Mesa 7.11-devel" is parsed as major "2", minor
"1 Mesa 7" (result in 0), leading to a version of 2.0 instead of 2.1.

To overcome this, use the common helper function in
QPlatformOpenGLContext.

Laszlo Agocs da2b3c4479 Prevent current context from becoming inconsistent upon create()
Platform plugins have a tendency to make the newly created native
context current with a temporary surface. This is usually needed to
query some information related to the new context. Afterwards most of
them just reset to having nothing current.

This has two issues:

It unexpectedly changes the current context/surface. A call into
QOpenGLContext::create() does not imply that the current context will
get changed. This is the minor issue and we could probably live with
it (at least if it had been documented).

However, the real issue is that QOpenGLContext::currentContext() will
become inconsistent: it will still report whatever was current before
the create() even though on the EGL/WGL/GLX level that's not the case
anymore.

To prevent all this confusion the platform plugins can easily be
changed to restore whatever context/surface was current before they
altered it.

Laszlo Agocs 32e2d8e58c Do not show warning on null result in getProcAddress
Other platforms do not do this either. What is more, some of the
extension handling code will try to resolve functions that are not
necessiarly present, and this is not an error.

Laszlo Agocs e7056a8969 Add context adoption support for WGL
This is trickier than the GLX and EGL implementations due to the
way pixel formats, windows and contexts work. Apart from some
restrictions, it should be fully functional nonetheless.

Add also some proper documentation.

Laszlo Agocs 39e0607825 Load winsys and gl dynamically in the windows plugin
The dynamic builds (-opengl dynamic) are now functional on Windows.

In such a build no components in Qt link to any OpenGL libraries directly
and qmake will not automatically add any such libraries to the
applications' makefiles. Instead, the libraries are chosen and loaded
during runtime and applications are expected to use QOpenGLFunctions
instead of direct OpenGLfunction calls.

Set the environment variable QT_OPENGL to desktop or angle to skip testing
and force the given implementation. The application attributes (AA_UseOpenGLES
and such) are also taken into account.

The testing logic is same as before: We try to load opengl32 and
resolve a shader related function. If this fails, ANGLE is chosen. This
allows utilizing full desktop OpenGL on systems that have proper drivers,
while a transparent fallback to ANGLE will be done automatically for
systems that don't. The latter includes also remote desktop connections.

Software rendering via Mesa llvmpipe is supported too. The fallback is
automatic on systems where the desktop test fails and ANGLE fails to load
or initialize (e.g. due to missing libs like d3dcompiler), as long as a
suitable patched build of Mesa is available.

[ChangeLog][QtGui] Dynamic OpenGL implementation loading is now supported
on Windows. This requires Qt to be configured with -opengl dynamic.
