QFileSystemEngine/Unix: use copy_file_range(2) in cloneFile()
For remote filesystems on Linux, this can invoke a server-side copy to
avoid network traffic. For local filesystems, Linux can use an optimized
FS-specific call (which may be the same operation as the FICLONE, but
I'm not sure) or splice the data on its own.
Tested with:
- FreeBSD ufs
- FreeBSD ufs-to-tmpfs
- FreeBSD tmpfs (tested ENOSPC with it)
- Linux btrfs
- Linux ext4
- Linux tmpfs (tested ENOSPC with it)
