Andreas Kling d6d7d11590 Kernel: Cache Custody objects (weakly) to avoid expensive reconstruction 
This patch adds a (spinlock-protected) custody cache. It's a simple
intrusive list containing all currently live custody objects.

This allows us to re-use existing custodies instead of creating them
again and again.

This gives a pretty decent performance improvement on "find /" :^)
