main: copyup uses reflinks if possible 
Use reflinks if they are supported by the underlying file system.

On my system, using XFS and reflinks, chowning recursively a directory
passed from:

User time (seconds): 0.02
System time (seconds): 0.34
Percent of CPU this job got: 8%
Elapsed (wall clock) time (h:mm:ss or m:ss): 0:04.52

to:

User time (seconds): 0.02
System time (seconds): 0.22
Percent of CPU this job got: 17%
Elapsed (wall clock) time (h:mm:ss or m:ss): 0:01.45

the performance improvement can be higher if the directory is made of
few but bigger files.

fuse-overlayfs: fix lookup with multiple layers 
when looking up multiple layers and we have already found a file, do
not check if whiteouts are present in lower layers.  The lookup in the
lower layers is needed only to correctly propagate the inode number.
