Thanks, this looks like mostly good stuff. Here's a new version of
the patch with some bug fixes, additional regression tests, and other
cleanup. I think this is about ready to commit. I didn't adopt your
documentation and I renamed your contrib module from dummy_esp to
dummy_seclabel, but the rest I took more or less as you had it. For
now, I don't want to use the term "external security provider" because
that's not really what this provides - it just provides labels. I
initially thought that an external security provider would really turn
out to be a concept that was somewhat embedded in the system, but on
further reflection I don't think that's the case. I think what we're
going to end up with is a collection of hooks that might happen to be
useful for security-related things, but not necessarily just those.
Anyway, I feel that it's a bit premature to document too much about
what this might do someday; the documentation already in the patch is
adequate to explain what it does now.
