If DllMain is used, rely on it working as expected. The old code seemed to attempt to free global state of other threads if, for some reason, the DllMain mechanism didn't work. In a static build, register a destructor with RegisterWaitForSingleObject. Make public functions xmlGetGlobalState and xmlInitializeGlobalState no-ops. Move initialization and registration of global state objects to xmlInitGlobalState. Lookup global state with xmlGetThreadLocalStorage which can be inlined nicely. Also cleanup global state when using TLS. xmlLastError must be reset.
