Antonio SJ Musumeci 07e7d76b7c Add support for file io passthrough 
If using Linux 6.9 or above and enabled (passthrough=true) files
opened or created will use the FUSE passthrough feature.

If direct-io=true / cache.files=off it will override passthrough. If
direct-io-allow-mmap is enabled only mmap will passthrough.

HANDLE_KILLPRIV and V2 are enabled now by default to remove the
kernel's need to issue getattr and getxattr requests.

moveonenospc will not work when leveraging passthrough.

speeds depending on the workload.

Antonio SJ Musumeci 93f7d7d927 add link_cow feature

based "CoW" solutions.
