extstore JBOD support

Just a Bunch Of Devices :P

code exists for routing specific devices to specific buckets
(lowttl/compact/etc), but enabling it requires significant fixes to
compaction algorithm. Thus it is disabled as of this writing.

code cleanups and future work:
 - pedantically freeing memory and closing fd's on exit
 - unify and flatten the free_bucket code
 - defines for free buckets
 - page eviction adjustment (force min-free per free bucket)
 - fix default calculation for compact_under and drop_under
   - might require forcing this value only on default bucket
