Always use '__thread' for Thread local storage except on MSVC

Use the GCC extension '__thread' [1] for Thread local storage on all C
and C++ compilers except MSVC.

While C11 and C++11 respectively offer '_Thread_local' and
'thread_local' as potentialy faster implementations, they offer no
guarantees of compatibility when used in a library interface which might
be used by both C and C++ client code.
