Title: Add c_purge performance counter to track object purges.

This performance counter tracks purges of individual objects, which is
typically done using the 'purge;' command in VCL. The counter tracks
actual objects purged, and not purge requests; this means that if
'purge;' is called on an object not in the cache it will not increment
the counter.
