Break the fs package up into smaller parts.
...
The purpose of this is to make it easier to maintain and eventually to
allow the rclone backends to be re-used in other projects without
having to use the rclone configuration system.
The new code layout is documented in CONTRIBUTING.

vfs: fix deletion of in use directories #1860
...
This was causing errors if the cache cleaner was called between the
Open and the pendingOpen of a RW file.
The fix was to move the cache open to the Open from the openPending.

incompatibility with cmount under windows.
