This PR is prompted by #3246. While looking through the code and understanding how IsLocked worked there, I realized that our fslock lib was missing a feature. Instead of asking @mastergaurang94 to fix it, I decided to completely migrate over to a more comprehensive locking solution, which additionally:

  • avoids the need custom code to maintain(NIHS)
  • solves the problem of locking being annoying after an ungraceful shutdown
  • gives us Windows and other niche OS support
    • as well as works around niche FS edge-cases

LGTM. General nit: f.Close calls Unlock under the hood, so you can unify the code by choosing only one method
