Paul Dagnelie a0f8d3c584 Add kstats tracking gang allocations 
Gang blocks have a significant impact on the long and short term
performance of a zpool, but there is not a lot of observability into
whether they're being used.  This change adds gang-specific kstats to
ZFS, to better allow users to see whether ganging is happening.
