Simon McVittie 17a23d08b5 dbus_threads_init_default, dbus_threads_init: be safe to call at any time
On Unix, we use a pthreads mutex, which can be allocated and
initialized in global memory.

On Windows, we use a CRITICAL_SECTION, together with a call to
InitializeCriticalSection() from the constructor of a global static
C++ object (thanks to Ralf Habacker for suggesting this approach).
