This patch addresses bugzilla #649, enabling `xm list' to display the

actual amount of memory allocated by a guest.  Also this patch:
  -  makes it more apparent that 'xm mem-set' has no effect on HVM's.
  -  show's that memory is changing if 'xm list' is issued while guest is
ballooning (w/o touching balloon driver)
