feature. We should pull those in.

The large dnode changes from 8423 caused problems in zfs recv for a legacy
stream. This manifests when attempting to mount the received stream, but the
problem is in the receive code. We missed the following commit from ZoL which
fixes this.
commit da2feb42fb5c7a8c1e1cc67f7a880da9d8e97bc2
Author: Tom Caputi <tcaputi@datto.com>

Fix 'zfs recv' of non large_dnode send streams
Currently, there is a bug where older send streams without the
DMU_BACKUP_FEATURE_LARGE_DNODE flag are not handled correctly.
The code in receive_object() fails to handle cases where
drro->drr_dn_slots is set to 0, which is always the case when the
sending code does not support this feature flag. This patch fixes
the issue by ensuring that that a value of 0 is treated as
DNODE_MIN_SLOTS.

In any pool without the extensible dataset feature flag already enabled,
creating a dataset with dedup set to use one of the new checksums would result
in the following panic as soon as any data was added:
panic[cpu0]/thread=ffffff0006761c40: feature_get_refcount(spa, feature,
&refcount) != 48 (0x30 != 0x30), file: ../../common/fs/zfs/zfeature.c line 390
ffffff0006761830 fffffffffba8fbdd ()
ffffff0006761890 zfs:feature_do_action+11a ()
ffffff00067618c0 zfs:spa_feature_incr+1e ()
ffffff0006761920 zfs:dmu_object_zapify+b7 ()
ffffff00067619b0 zfs:dsl_dataset_activate_feature+97 ()
ffffff0006761a20 zfs:dsl_dataset_sync+ba ()
ffffff0006761ab0 zfs:dsl_pool_sync+153 ()
ffffff0006761b70 zfs:spa_sync+26e ()
ffffff0006761c20 zfs:txg_sync_thread+227 ()
ffffff0006761c30 unix:thread_start+8 ()
Inspection showed that feature->fi_feature was 7, which is the value of
SPA_FEATURE_EXTENSIBLE_DATASET in the spa_feature enum.
Testing shows that the panic can be prevented by explicitly setting extensible
dataset as a dependency for the sha512, edonr, and skein feature flags.
Alternatively, the new checksums code could possibly be changed to obviate the
need for the dependency.

It is intended to assist the creation and management of virtual machines
that have their rootfs on ZFS on hosts that also have their rootfs on
ZFS. These situations cause SPA namespace collisions when the standard
name rpool is used in both cases. The solution is either to give each
guest pool a name unique to the host, which is not always desireable, or
boot a VM environment containing an ISO image to install it, which is
cumbersome.
As a side note, this commit includes the removal of `zpool import -r`,
which previously did nothing.

The zfs_dbuf_evict_key TSD (thread-specific data) is not necessary - we can
instead pass a flag down in a few places to prevent recursive dbuf eviction.
Making this change has 3 benefits:
1. The code semantics are easier to understand.
2. On Linux, performance is improved, because creating/removing TSD values
(by setting to NULL vs non-NULL) is expensive, and we do it very often.
3. According to Nexenta, the current semantics can cause a deadlock when
concurrently calling dmu_objset_evict_dbufs() (which is rare today, but they
are working on a "parallel unmount" change that triggers this more easily)

Ultimately, the problem here is that when you truncate and write a file in
the same transaction group, the dbuf for the indirect block will be zeroed
out to deal with the truncation, and then written for the write. During
this process, we will lose hole birth time information for any holes in the
range. In the case where a dnode is being freed, we need to determine
whether the block should be converted to a higher-level hole in the zio
pipeline, and if so do it when the dnode is being synced out.

In the most fragmented real-world cases, this reduces memory used by the
mapping from ~1GB to ~50MB of RAM per 1TB of storage removed. Less
fragmented cases will typically also see around 50-100MB of RAM per 1TB
of storage.

it would be better if it copied any data necessary from the config and the
