Yes, these are unrelated changes but somehow ended up being
prototyped together and I'm too lazy to separate them.

8adebc9489 new features: follow-symlinks, rename-exdev, link-exdev 
* follow-symlinks: allows mergerfs to transparently follow symlinks

  create a symlink for the newpath

6ecc618d83 remove .fuse_hidden file creation 
addresses #521

mergerfs is written using libfuse's high level API. The HLAPI forces a certain
behavior with regard to unlinking or rename overwriting of open files. It
renames the file to .fuse_hiddenXXXXXX and when incoming requests refer
to the unlinked file it will use path based calls and use that path.

This behavior leads to rmdirs failing or some software noticing
the .fuse_hidden files.

This patch changes the HLAPI and removes entirely the .fuse_hidden behavior.

See the README for more.
