RedirFS

This is an attempt to resurrect and extend the discontinued redirfs project from https://github.com/fhrbata/redirfs

What's new:

the redirfs.ko module was made compilable up to 4.14 kernel
some fixies to vfsmount usage
complete set of file_operations
address_space_operations support
shared object for hooked operations instead of a per-object structure
new object model to manage reference counting
character devices operations (requires adding /dev path as redirfs_add_path doesn't cross mount points)
debug build without optimization (make modules_debug)
