Replace GlobalLock functions with std::mutex

Browse source 
The usage of GetGlobalLock/ReleaseGlobalLock/InitGlobalLock is replaced
by std::lock_guard which is available as of c++11, and the functions are
removed from the OSDependent ossource.cpp files.
The standalone glslang binary now explicitly depends on OSDependent, as
nothing in in the glslang library uses those functions anymore and they
are not implicitly picked up by the linker.
