ZoL issues:
Improved dnode allocation #6564
Clean up large dnode code #6262
Fix dnode_hold() freeing dnode behavior #8172
Fix dnode allocation race #6414, #6439
Partial: Raw sends must be able to decrease nlevels #6821, #6864
Remove unnecessary txg syncs from receive_object() Closes #7197

This updates FreeBSD large_dnode code (that was imported from ZoL) to a version
that was committed to illumos. It has some cleanups, improvements and fixes
comparing to what we have in FreeBSD now. I think that the most significant
update is 8199 multi-threaded dmu_object_alloc().

Obtained from: illumos
