Make it possible to clone a mount tree with a new pair of open flags that
are used in conjunction with O_PATH:
(1) O_CLONE_MOUNT - Clone the mount or mount tree at the path.
(2) O_NON_RECURSIVE - Don't clone recursively.
Err. I don't think we should use up two O_* flags for something
only useful for your new mount API. Don't we have a better place
to for these flags?
Instead of overloading this on open having a specific syscalls just
seems like a much saner idea.
It's not just mount API; these can be used independently of that.
Think of the uses where you pass those to ...at() and you'll see
a bunch of applications of that thing.
