  Message : Fix gl::Context::unMakeCurrent crashes The crash is because Display::makeCurrent() may fail, in that case, egl_stubs.cpp will not update the current context in global_state and Thread accordingly. And then Context::refCount could be reach 0, and be released, however egl_stubs.cpp still thinks the context is current, and then user-after-free happens. This CL fixes the problem by updating current context of Thread in Display::makeCurrent, and reading the current context of Thread in egl_stubs.cpp and setting it to global_state.
