The Linux kernel commit b40000325044 ("virtio_balloon: add array
of stat names") defines an array of stat name strings for consumers
of the virtio interface to use via the virtio_balloon.h header
file, rather than requiring each consumer to define its own. But at
present, the stat names defined in this array by the Linux kernel
do not match up with those defined internally by QEMU. This patch
fixes this inconsistency by changing the QEMU stat names to match
those defined by the Linux kernel.

So pls import the header from Linux so we can stop maintaining it
in QEMU.

Hi Michael,
Thank you for your comment. Because Jonathan left the company last week,
I hope to pick up what he left over. As far as the importing the header
file, please let me look into it and get back to you.
Thank you,
Thomas
