D7252: dirs: reject consecutive slashes in paths

[Alphare (Raphaël Gomès)]

Alphare added a comment.


  Sorry to necropost, but since this broke the Rust implementation, I was wondering what the best approach would be to replicate this behavior, and I am starting to think that this should be reverted.
  
  IIUC, currently any new path passes through the `pathauditor` first for validation, so any further check would be completely redundant. 
  My intuition is that adding this check is purely here to satisfy the fuzzer, but would never happen in real life. Adding checks to this (very) internal data structure comes at a cost, both in performance and in code ergonomics.
