this turns mouninfo into a multicall binary which can also do parallel unmounting. most mountinfo code is unchanged; only notable change is find_mounts() now returns the number of mounts found and also takes the "process" function as an argument; so that is_mounted() can be implemented on top of it. do_unmount mostly follows the logic of previous code. some notable changes: - do_unmount is now "lazy" when it comes to retrying failed unmounts. it will greedily keep running unmount as long as it can before it looks at the "waiting" queue. - it will check if the mountpoint is still mounted or not when umount returns non-zero exit code. this is due to the fact that multiple umount calls might race to unmount a shared mount. so if umount fails _but_ the mountpoint is no longer mounted, we assume success. - do_unmount used to fail if fuser did not find any pids using the mount. the new code tries one more time; the rationale being that there's a gap between the umount call and the fuser call, and so whatever was using the mount before might have stopped using it now and so it's worth another attempt.
