Pull overlayfs updates from Amir Goldstein:

 - Increase robustness of overlayfs to crashes in the case of underlying
   filesystems that to not guarantee metadata ordering to persistent
   storage (problem was reported with ubifs).

 - Deny mount inside container with features that require root
   privileges to work properly, instead of failing operations later.

 - Some clarifications to overlayfs documentation.
