Async writes triggered by a self-healing IO may be issued before the
pool finishes the process of initialization. This results in a NULL
dereference of `spa->spa_dsl_pool` in vdev_queue_max_async_writes().
George Wilson recommended addressing this issue by initializing the
passed `dsl_pool_t **` prior to dmu_objset_open_impl(). Since the
caller is passing the `spa->spa_dsl_pool` this has the effect of
ensuring it's initialized.
However, since this depends on the caller knowing they must pass
the `spa->spa_dsl_pool` an additional NULL check was added to
vdev_queue_max_async_writes(). This guards against any future
restructuring of the code which might result in dsl_pool_init()
being called differently.

* Disable zfs-import-scan.service by default. This ensures that
pools will not be automatically imported unless they appear in
the cache file. When this service is explicitly enabled pools
will be imported with the "cachefile=none" property set. This
prevents the creation of, or update to, an existing cache file.

* Change services to dynamic from static by adding an [Install]

This allows for easier customization of the boot behavior.
* Start the zfs-import-cache.service after the root pivot so

* Start the zfs-mount.service after the systemd-remount-fs.service
to ensure the root fs is writeable and the ZFS filesystems can
create their mount points.
* Change the default behavior to only load the ZFS kernel modules
in zfs-import-*.service or when blkid(8) detects a pool. Users
who wish to unconditionally load the kernel modules must uncomment
the list of modules in /lib/modules-load.d/zfs.conf.

Porting notes:
- Added new IO delay tracepoints, and moved common ZIO tracepoint macros
to a new trace_common.h file.
- Used zio_delay_taskq() in place of OpenZFS's timeout_generic() function.
- Updated zinject man page
- Updated zpool_scrub test files
arc_prune_task uses a refcount to protect arc_prune_t, but it doesn't prevent
the underlying zsb from disappearing if there's a concurrent umount. We fix
this by force the caller of arc_remove_prune_callback to wait for
arc_prune_taskq to finish.

Issue #4024
struct zvol_state contains a dummy znode, which is around 1KB on x64,
only for zfs_range_lock. But in reality, other than z_range_lock and
z_range_avl, zfs_range_lock only need znode on regular file, which
means we add 1KB on a structure and gain nothing.
In this patch, we remove the dummy znode for zvol_state. In order to
do that, we also need to refactor zfs_range_lock a bit. We move
z_range_lock and z_range_avl pair out of znode_t to form zfs_rlock_t.
This new struct replaces znode_t as the main handle inside the range
lock functions.
We also add pointers to z_size, z_blksz, and z_max_blksz so range lock
code doesn't depend on znode_t. This allows non-ZPL consumers like
Lustre to use the range locks with their equivalent znode_t structure.
