Epoxy automatically fetches the extension functions on demand, including
the GLX context creation functions. This means that you can't test the
function pointers for NULL anymore, because they're always set to a
resolver function until the first call. Instead, you have to check for the
availability of an extension by the extension's name. Thanks to Isilkor for
catching these.
On windows, epoxy invalidates all extension function pointers when the
GL context changes. This means we need to have an active context at all
times we call an extension function (like wglGetPixelFormatAttribivARB)
or else the code will jump to an invalid pointer. On the other hand, we do
not need to make it reinitialize the pointers ourselves.
Epoxy automatically uses an alias for a function if the requested name is
not available, like glDebugMessageCallbackARB instead of
glDebugMessageCallback. It also does not have the problem with varying
parameter types for that function. So switch to it while removing
GLDEBUGPROCARB_USERPARAM_IS_CONST.
This employs a rather ugly hack to make CMake do what we want. CMake
doesn't allow us to add items directly to the solution (as opposed to
one of the projects inside it), and thus requires us to abuse its lack
of parameter validation to manually add the file.
Currently, all music pieces are kept in memory to avoid random group access, which is a bit excessive for the larger music pack. This change will allow runtime music loads without too much delay.
f897e95071 broke this by reusing the macro with the path to the binary
as the binary name, which doesn't work if the path contains directories.
Also, 0dcfe72148 moved the binaries, but the LOCATION property still
pointed to the old location. Luckily, CMake also has a non-broken option to
pass target file paths to custom commands.
Apparently, the Games Explorer is a failed experiment. Players don't expect
a game to only appear there, lots of games do not bother with it, and
future windows versions don't include it.

Since the name of the game is OpenClonk, having the binary named
differently is at least confusing. At worst it conflicts with the
trademark license granted by RedWolf Design.
The Mac build will still have to be fixed because the installer
template .dmg file is not editable on non-Macintosh systems.
This makes it possible to ship the bundle stand-alone. Also
note that CMake will automatically pack the game data for
release builds, but sym-link the game data for debug builds.
Note this means you will only see the parts of planet/ that
are mentioned in OC_C4GROUPS in CMakeList.txt! This is equivalent
to the behaviour of the shipped build, so I don't see this as
a problem.
