Originally I tried to reuse the indirect delete to accomplish truely atomic directory removes, however this fell apart when it came to implementing directory removes as a side-effect of renames. A single indirect-delete simply can't handle renames with removes as a side effects. When copying an entry to its destination, we need to atomically delete both the old entry, and the source of our copy. We can't delete both with only a single indirect-delete. It is possible to accomplish this with two indirect-deletes, but this is such an uncommon case that it's really not worth supporting efficiently due to how expensive globals are. I also dropped indirect-deletes for normal directory removes. I may add it back later, but at the moment it's extra code cost for that's not traveled very often. As a result, restructured the indirect delete handling to be a bit more generic, now with a multipurpose lfs_globals_t struct instead of the delete specific lfs_entry_t struct. Also worked on integrating xored-globals, now with several primitive global operations to manage fetching/updating globals on disk.
