Increasingly there are a number of components that want to do some cleanup at global shutdown time (at least if there are not going to be memory leaks). This creates a very simple system of shutdown hooks that will be invoked by git_threads_shutdown. Right now, the maximum number of hooks is hardcoded, but since adding a hook is not a public API, it should be fine and I thought it was better to start off with really simple code.
