Subject: Implement negative lookup cache

Before creating any file negative lookups(1 in Fuse, 4 in SMB etc.)
are sent to verify if the file already exists. By serving these
lookups from the cache when possible, increases the create
performance by multiple folds in SMB access and some percentage
in Fuse/NFS access.
