Making them the same type is simply confusing, but also means that you
could accidentally use one in the wrong context. This eliminates that
problem. This also includes a whole bunch of cleanups for the types
within DeviceRule, so that they can be used more ergonomically.

These lists have been in the codebase for a very long time, and have
been unused for a large portion of that time -- specconv doesn't
generate them and the only user of these flags has been tests (which
doesn't inspire much confidence).
In addition, we had an incorrect implementation of a white-list policy.
This wasn't exploitable because all of our users explicitly specify
"deny all" as the first rule, but it was a pretty glaring issue that
came from the "feature" that users can select whether they prefer a
white- or black- list. Fix this by always writing a deny-all rule (which
is what our users were doing anyway, to work around this bug).
This is one of many changes needed to clean up the devices cgroup code.

split fs2 package from fs, as mixing up fs and fs2 is very likely to result in
unmaintainable code.
