The __attribute__((constructor)) init_main_loop() automatically get called if qemu-tool.o is linked in. On win32, this leads to a qemu_notify_event() call which attempts to SetEvent() on a HANDLE that won't be initialized until qemu_init_main_loop() is manually called, breaking qemu-tools.o programs on Windows at runtime. This patch checks for an initialized event handle before attempting to set it, which is analoguous to how we deal with an unitialized io_thread_fd in the posix implementation.
