Martin Gräßlin ac1dbac8b1 Handle conflicts between epoxy and manually resolved function pointers
For the functions from GL_FOO_robustness we want to resolve it by
ourselves in order to add a custom implementation if it's not available.
Unfortunately once epoxy.h is included this breaks as epoxy defines the
names and so through the preprocessor epoxy always wins.

So we need different names: all functions from robustness get a "kwin"
prefix and the usage is changed everywhere in kwin source code.
