util: enable hardlink for copyfile This patch removes the global variable "allowhardlinks" that disables hardlink in all cases, so hardlink gets enabled if the filesystem type is whitelisted. Third party extensions wanting to enable hardlink support unconditionally can replace "_hardlinkfswhitelist.__contains__".
