If a system administrator happens to type `ostree admin upgrade` multiple times, currently that will lead to a potentially corrupted system. I originally attempted to do locking *internally* in `libostree`, but that didn't work out because currently a number of the commands perform multi-step operations that all need to be serialized. All of the current code in `ostree admin deploy` is an example. Therefore, allow callers to perform locking, as most of the higher level logic is presently implemented there. At some point, we can revisit having internal locking, but it will be difficult. A more likely approach would be similar to Java's approach with concurrency on iterators - a "fail fast" method.
