The existing rules miss nvme disk devices because of the trailing
digits in the KERNEL device name, e.g. nvme0n1. Partitions of nvme
disk devices are already properly handled by the existing rule for
ENV{DEVTYPE}=="partition".

Add an 'enclosure_symlinks' option to vdev_id.conf. This creates
consistently named symlinks to the enclosure devices (/dev/sg*) based
off the configuration in vdev_id.conf. The enclosure symlinks show
up in /dev/by-enclosure/<prefix>-<channel><num>. The links make it
make it easy to run sg_ses on a particular enclosure device. The
enclosure links are created in addition to the normal
/dev/disk/by-vdev links.
'enclosure_symlinks' is only valid in sas_direct configurations.

When pools are assembled from partitions, vdev_id.conf aliases
do not work. The directory /dev/disk/by-vdev is not created because
the associated udev rule for parsing vdev_id.conf is never called.
Extend to logic to match "disk" and "partition".

Add a vdev_id feature to map device names based on already defined
udev device links. To increase the odds that vdev_id will run after
the rules it depends on, increase the vdev.rules rule number from 60
to 69. With this change, vdev_id now provides functionality analogous
to zpool_id and zpool_layout, paving the way to retire those tools.
A defined alias takes precedence over a topology-derived name, but the
two naming methods can otherwise coexist. For example, one might name
drives in a JBOD with the sas_direct topology while naming an internal
L2ARC device with an alias.
For example, the following lines in vdev_id.conf will result in the
creation of links /dev/disk/by-vdev/{d1,d2}, each pointing to the same
target as the device link specified in the third field.
# by-vdev
# name fully qualified or base name of device link
alias d1 /dev/disk/by-id/wwn-0x5000c5002de3b9ca
alias d2 wwn-0x5000c5002def789e
Also perform some minor vdev_id cleanup, such as removal of the unused
-s command line option.
