Hey everyone,

This ports overlayfs to the new mount api and modifies layer parsing to
allow for additive layer specification via fsconfig().

I'm not sure if I need to rebase the changes on top of Amir's lazy
lookup. If so, please let me know!

Changes in v2:
- Split into two patches. First patch ports to new mount api without changing
  layer parsing. Second patch implements new layer parsing.
- Move layer parsing into a separate file.
- Link to v1: https://lore.kernel.org/r/20230605-fs-overlayfs-mount_api-v1-1-a8d78c3fbeaf@kernel.org

Yes, please.

I look at the conflicts and they don't look so bad.
I think only need to figure out numlowerdata during parsing
which should be pretty easy and then the entire wacky loop
to figure out numlowerdata in ovl_get_lowerstack() can be nuked.
all the rest stays the same.

Thanks,
Amir.
