smaps: add pages referenced count to smaps
Adds an additional unsigned long field to struct mem_size_stats called 'referenced'. For each pte walked in the smaps code, this field is incremented by PAGE_SIZE if it has pte-reference bits. An additional line was added to the /proc/pid/smaps output for each VMA to indicate how many pages within it are currently marked as referenced or accessed.
