If the fields to be listed and sorted by are constrained
to those populated by dsl_dataset_fast_stat(), then
zfs list is much faster, as it does not need to open each
objset and reads its properties.
A previous optimization by Pawel Dawidek
(0cee24064a) took advantage
of this to make listing snapshot names sorted only by name
much faster.
However, it was limited to `-o name -s name`, this work
extends this optimization to work with:
- name
- guid
- createtxg
- numclones
- inconsistent
- redacted
- origin
and could be further extended to any other properties
supported by dsl_dataset_fast_stat() or similar, that do
not require extra locking or reading from disk.

Add properties, similar to pool properties, to each vdev.
This makes use of the existing per-vdev ZAP that was added as
part of device evacuation/removal.
A large number of read-only properties are exposed,
many of the members of struct vdev_t, that provide useful
statistics.
Adds support for read-only "removing" vdev property.
Adds the "allocating" property that defaults to "on" and
can be set to "off" to prevent future allocations from that
top-level vdev.
Supports user-defined vdev properties.
Includes support for properties.vdev in SYSFS.

One of our developers noticed a bug in vdev_id where we were incorrectly
sorting PHYs using alphabetical sorting (which usually works) instead
of natural sorting (-v). For example:
[port-0:0]# ls -d phy*
phy-0:10 phy-0:11 phy-0:8 phy-0:9
[port-0:0]# ls -vd phy*
phy-0:8 phy-0:9 phy-0:10 phy-0:11

The vdev_id.conf "enclosure_symlinks" option persistently creates
and maps /dev/by-enclosure symlinks to dynamic /dev/sg* devices.
This patch fixes two issues:
1. The enclosure_symlinks feature was accidentally broken in:
vdev_id: Support daisy-chained JBODs in multipath mode
2. Even when working, the feature numbered the enclosure
sequentially rather than by HBA port number. That meant that
if a port was down or didn't appear in sysfs, then the
enclosure_sumlinks numbers would be numbered wrong.
