For GLVND reasons the client/platform extensions strings should be split. While in the non GLVND case they're one big string. Currently we handle this distinction at run-time for not obvious reason. Adding additional code and complexity. Swap those with a few well placed #if USE_LIBGLVND guards. As a side result this removes a minor memory leak due to the concatenation in the non GLVND case.
