new features: follow-symlinks, rename-exdev, link-exdev
* follow-symlinks: allows mergerfs to transparently follow symlinks * link-exdev: in the event a link returns EXDEV create a symlink instead * rename-exdev: in the event a rename returns EXDEV move the oldpath and create a symlink for the newpathpull/883/head
