Create the most fragmented pool possible and try to defragment it.

- allocate multiple copies of graph nodes
    - nodes in each copy are randomly ordered
- pick one copy of each node and free all others
    - generating possibly most fragmented pmemobj pool
- store PMEMoids to other nodes within each node (the edges)
- defragment the pmemobj pool
- verify the result

obj: introduce new statistics useful for defrag

With this patch, all transients statistics will be enabled by default,
and users will have ability to selectively disable or enable both types
of statistics. This changes the stats.enabled entry point, but in
a backward compatible way.

This patch introduces two new statistics: stats.heap.run_active and
stats.heap.run_allocated. Combination of these two can be used to
estimate the total potentially unused space in the heap, indicating
that defrag should be ran.

obj: implement naive user assisted defrag

pool: accept "Machine" of "PPC64"

pmem: change ppc64 init logs to experimental

test: fix lane and arena offsets in unittest.sh

pool: fix btt offset calculation

test: fix pmemspoil blk arena offset
