Thread IO safety: annotate file_util, and block IO thread from doing IO
- Mark functions in file_util_posix as requiring permission to perform disk actions. - Mark the IO thread as disallowed from performing disk actions. - Temporarily work around the protections in places where we currently have bugs.
