rHG8d585aa9becf: dirstate: drop comparison primitive on the timestamp class
Summary

All comparison are now managed without using operator :

  • the status mtime comparisons is handled by the DirstateItem,
  • the fixup reliability check,
  • the update "hack".

So we no longer needs the operator and should discourage its usage.
