* don't execute OpenGL test app if user selected XRender
* don't execute OpenGL test app if user forces to EGL
If a user selected XRender because OpenGL is failing badly it might not
be the best idea to call an OpenGL application.
If the user enforces EGL it's kind of pointless to call a testapp which
uses GLX.

This was currently basically broken:
* Screen number got always attached
* openGLIsBroken did not check for screen number
-> KCM reported "everything is fine" while it wasn't
Now changed to:
* only attach screen number if it is a multi-head setup
* use same logic in both Composite and CompositingPrefs
Still problematic:
* kcm is not multi-head aware so it will report everything is fine in
case of a broken multi-head setup

Many headers included KLocale to use i18n and co. But those methods are
defined in KLocalizedString and not in KLocale.
With KF5 klocale.h does no longer include KLocalizedString causing lots
of compile errors.
The extension handling is removed from kwinglobals and moved into the
xcbutils in KWin core in namespace KWin::Xcb. The motivation for this
change is that the Extensions are only used in KWin core and are marked
as internal. So there is no need to have them in the library.
What remains in Extensions are the non-native pixmaps. This will be
removed once we are on Qt 5 as QPixmap can no longer reference an XPixmap.
The remaining code in kwinglobals also still initialize the XLib versions
of extensions emitting events. It seems like there are no XEvents emitted
if not done so even if the extension is correctly initialized with xcb.
This needs to be removed once the event handling is ported over to xcb.

Whether creating the OpenGL context succeeds or not
had no influence in any decisions on the used settings
for OpenGL based compositing.
The only valid information CompositingPrefs still detects
is whether direct rendering should be used which is
performed out of process and does not require a context.
So overall the context creation is not needed and can
be removed.

This means the GLPlatform is filled with values from the
context actually used for Compositing and if XRender
compositing is used no OpenGL information is logged.
There is no need to have it driver specific any more.
All drivers seem to support it (only Intel had been
opt-ed out without any apparent reason shown in commit log).
This was the last driver specific setting which means that
the method applyDriverSpecificSettings() got dropped from
CompositingPrefs.
Strict binding follows the driver (GLPlattform) unless
the user has a config value specified in the kwinrc.
For this a new property is added to Options to indicate
whether strict binding is user defined or follows the
driver. In case of driver the strict binding option is
set when OpenGL compositor starts up.
Due to changes in build system we have always either OpenGL or OpenGL ES.
This allows to remove the KWIN_HAVE_OPENGL_COMPOSITING define. In the
effects the define is kept as KWIN_HAVE_OPENGL which can be used in
future to build also an XRender only effect system.
Building the workspaces requires to have all the build dependencies
which were required for KWIN_HAVE_COMPOSITING to be set. This allows
us to remove all the ifdefs for this and gives us a cleaner code.
The advanced compositing option "direct rendering" could only
correctly be honored in the case of proprietary NVIDIA drivers.
In all other cases playing with the setting was most likely
harmful as it could result in inconsistent states and the
option not to be honored at all.
This patch resolves this issue by moving the detection whether
to use a direct rendering context completely into the hands of
the set environment variables or the helper program:
* if LIBGL_ALWAYS_INDIRECT is set, we use an indirect context
* if KWIN_DIRECT_GL is set, we use a direct context
* if none of the two are set, we use the helper program, if it
returns 0 we create a direct context, otherwise we set
LIBGL_ALWAYS_INDIRECT and create an indirect context
If a user really wants to influence the behavior the
environment variables can be used.

Removes the Extension::glxAvailable() from kwinglobals and
implements the functionality in CompositingPrefs, where it
is only needed. There used to be one additional check in
scene_opengl_glx.cpp which is moved into composite.cpp
before the OpenGL Scene is created.

Unknown, unknown just looks bad given that we will have more
nouveau users in future. Neither the vendor, nor the renderer
nor the version string contains a version number. The information
most close to a version number is the gallium number. Other
possible number would be OpenGL version or Mesa version in the
GL version string, but those information is not used in other
Mesa drivers.

I've had missing compositing since about a week on my ATI x1300.
After a bit of debugging with the help of fredrikh and mgraesslin, the version string reported seems to be the culprit. I've special-cased the different version string for the R300 driver and it works again now.
The strings my r300 reports are:
DRI R300 Project
Mesa DRI R300 (RV515 7149) 20090101 x86/MMX/SSE2 TCL
1.4 (1.5 Mesa 7.6)
