copyfile: allow optional hardlinking
Some code paths use 'copyfiles' (full tree) for a single file to take advantage
of the best-effort-hard-linking parameter. We add similar parameter and logic
to 'copyfile' (single file) for this purpose.
The single file version have the advantage to overwrite the destination file if
it exists.
