manu 2ff0ea03a7 - Correctly handle rename whith overwritten destination
- Keep track of file name to avoid lookups when we can. This makes sure we
  do not have two cookies for the same inode, a situation that cause wreak
  havoc when we come to remove or rename a node.
- Do not use PUFFS_FLAG_BUILDPATH at all, since we now track file names
- In open, queue requests after checking for access, as there is no merit
  to queue a will-be-denied request while we can deny it immediatly
- request reclaim of removed nodes at inactive stage
