[PATCH] Add some simple end-to-end tests for btrfs-convert.
These use the system's mke2fs, and don't require loop devices or root privileges. They don't pick up anything with the default flags right now, but they do pick up some sanitizer issues when the tools are compiled with any of -fsanitize={address,memory,thread}.
