🐛 | Drupal core | [D7] file_unmanaged_move() should issue rename() where possible instead of copy() & unlink()

re-rolled #9 for D7 head (7.54) as the previous patch doesn't apply.
interdiff is pretty hard to interpret, as the patch had to be manually applied, and the changes are resulted in just different line numbers.
I have not extensively tested the patch yet.
