This is the buffer size passed to ddt_object_name(), to expand the
DMU_POOL_DDT format. That format inserts the table checksum, class and
type names, which as I write this are max 6, 9 and 3, respectively.

Store objects store keys and values, so have them take those types and
nothing more. This way, they don't need to be concerned about the "kind"
of entry being operated on; the dispatch layer can take care of the
appropriate conversions.
This adds a "contains" op to see if a particular entry exists without
loading it, which makes a couple of things easier to do; in particular,
it allows us to avoid an allocation in ddt_class_contains().

Things get confused when there's more than one name for a thing.
Note that we don't do this for ddt_object_t, ddt_histogram_t and
ddt_stat_t because they're part of the public ZFS interface.

Mostly for consistency, so the reader is less likely to wonder why these
things look different.
