Mauro Rossi b0028a446c ANDROID: mnt: Add filesystem private data to mount points (v2) ...

This starts to add private data associated directly
to mount points. The intent is to give filesystems
a sense of where they have come from, as a means of
letting a filesystem take different actions based on
this information.

(v2)
