Balloon driver tests

Balloon driver tests

Here's a small set of tests I've written for the balloon driver.  I'm 
sure there's more that could be tested, but it's a start.  Can/should 
these go in the tests directory?

Here's a brief description of each and a tarball since it would be 
cumbersome to send them all inline:

balloon01: Test read from /proc/xen/balloon
balloon02: Echo a number higher than current requested allocation to 
/proc/xen/balloon, cat balloon and see that requested target changed.
balloon03: Echo a number lower than current requested allocation to 
/proc/xen/balloon, cat balloon and see that requested target changed.
balloon04: Allocate some memory for the domain, then use 
/proc/xen/balloon to reduce available memory to less than what is allocated
balloon05: Try to give /proc/xen/balloon a value larger than the 
available RAM in the system.
balloon06: Try to give /proc/xen/balloon a value way too low, such as 4k
balloon07: Open /proc/xen/balloon as non-root user, expect -EACCES
balloon08: Write 1 byte to /proc/xen/balloon, expect -EBADMSG
balloon09: Write >64 bytes to /proc/xen/balloon, expect -EFBIG

Thanks,
Paul Larson
