ENH: use linux fallocate to reserve diskspace in array.tofile
fallocate allows the filesystem to make smarter decisions about space
allocation and gives a fast failure path for insufficient space.
This is very important for filesystems that suffer a lot from
fragmentation like btrfs.
Restricted to linux only as that is the only system I know the behavior
of. Other systems might also have this system call but we don't want to
accidentally trigger explicit zeroing behavior as e.g. posix_fallocate
would when there is no support for a real fallocate.
