When doing recv and rollback, dsl_dataset_clone_swap_sync_impl will be
called to swap out the ds_objset and do dmu_objset_evict on the old one.
However, currently zv->zv_objset will not be swapped out accordingly, so
if anyone currently holds a fd on the zvol, we risk hitting a use-after-free.
We fix this by introducing the suspend and resume mechanism of zsb to
zv. Before recv or rollback, we use zvol_suspend to block all access to
zv_objset and shut it down. After the recv or rollback, we use zvol_resume
to swap in zv_objset with the new ds_objset and unblock the access.

Fix dmu_object_next() to correctly handle unallocated objects on
large_dnode datasets.
We implement this by scanning the dnode block until we find the correct
offset to be used in dnode_next_offset(). This is necessary because we
can't assume *objectp is a hole even if dmu_object_info() returns
ENOENT.
This fixes a couple of issues with zfs receive on large_dnode datasets.

Add *_by_dnode() routines for accessing objects given their
dnode_t *, this is more efficient than accessing the object by
(objset_t *, uint64_t object). This change converts some but
not all of the existing consumers. As performance-sensitive
code paths are discovered they should be converted to use
these routines.

When loading a pool that had been created before the existance of
per-vdev zaps, on a system that knows about per-vdev zaps, the
per-vdev zaps will not be allocated and initialized.
This appears to be because the logic that would have done so, in
spa_sync_config_object(), is not reached under normal operation. It is
only reached if spa_config_dirty_list is non-empty.
The fix is to add another `AVZ_ACTION_` enum that will allow this code
to be reached when we detect that we're loading an old pool, even when
there are no dirty configs.

[bio] The req_op enum was changed to req_opf. Update the "Linux 4.8 API"
autotools checks to use an int to determine whether the various REQ_OP
values are defined. This should work properly on kernels >= 4.8.
[bio] bio_set_op_attrs() is now an inline function and can't be detected
with #ifdef. Add a configure check to determine whether bio_set_op_attrs()
is defined. Move the local definition of it from vdev_disk.c to
blkdev_compat.h for consistency with other related compability shims.
[bio] The read/write flags and their modifiers, including WRITE_FLUSH,
WRITE_FUA and WRITE_FLUSH_FUA have been removed from fs.h. Add the new
bio_set_flush() compatibility wrapper to replace VDEV_WRITE_FLUSH_FUA
and set the flags appropriately for each supported kernel version.
[vfs] The generic_readlink() function has been made static. If .readlink
in inode_operations is NULL, generic_readlink() is used.
