Use single tree for multiple storage views.
Instead of having each view build and maintain its own tree
representing the underlying storage, switch to building a single tree
that each view augments with GID/mode specific behavior.
This has the nice property of a single file always having the same
node ID when presented across multiple views, giving us a firm handle
that we can use to invalidate kernel caches.
Specifically, when a file is deleted through one view, we now tell
the kernel to invalidate that file in the other two views.
