Okay, I'll follow up this mail with a pair of patches to just use network
namespacing in AFS.  The first exports a function from core code only; the
second is the actual modifications to AFS.

Note that this doesn't actually yet permit AFS to use any other namespace.
The propagation-over-automount issue is handled by a separate patch.
