main: introduce inodes cache 
introduce a hash map to refer from an inode to the file paths.
A recent change where we enable FUSE writeback by default uncovered an
underlying issue in fuse-overlayfs where changes to a file with
multiple links would not be visible from the other link.

For each inode, maintain a list of nodes that refer to it, so that we
can still access it when a link is removed and more importantly we can
use the inode value with FUSE.
