Derek McGowan 23e5c94cfb Add separate overlay2 driver 
Adds a new overlay driver which uses multiple lower directories to create the union fs.
Additionally it uses symlinks and relative mount paths to allow a depth of 128 and stay within the mount page size limit.
Diffs and done directly over a single directory allowing diffs to be done efficiently and without the need fo the naive diff driver.
