linux: implement filesystem-side copy/clone functions
This implements the Linux VFS ops required to service the file
copy/clone APIs:
.copy_file_range (4.5+)
.clone_file_range (4.5-4.19)
.dedupe_file_range (4.5-4.19)
.remap_file_range (4.20+)
Note that dedupe_file_range() and remap_file_range(REMAP_FILE_DEDUP) are
hooked up here, but are not implemented yet.
