similar to: [PATCH] virtio_balloon: export huge page allocation statistics

Export the number of successful and failed hugetlb page allocations via the virtio balloon driver. These 2 counts come directly from the vm_events HTLB_BUDDY_PGALLOC and HTLB_BUDDY_PGALLOC_FAIL.

Jason Wang points out that it's vary hard for users to build an array of stat names. The naive thing is to use VIRTIO_BALLOON_S_NR but that breaks if we add more stats. Let's add an array of reasonably readable names.

Add a new field VIRTIO_BALLOON_S_CACHES to virtio_balloon memory statistics protocol. The value represents all disk/file caches. In this case it corresponds to the sum of values Buffers+Cached+SwapCached from /proc/meminfo. Signed-off-by: Tom??
