In the interest of maintaining only one udev helper to give vdevs
user friendly names, the zpool_id and zpool_layout infrastructure
is being retired. They are superseded by vdev_id which incorporates
all the previous functionality.
Documentation for the new vdev_id(8) helper and its configuration
file, vdev_id.conf(5), can be found in their respective man pages.
Several useful example files are installed under /etc/zfs/.
/etc/zfs/vdev_id.conf.alias.example
/etc/zfs/vdev_id.conf.multipath.example
/etc/zfs/vdev_id.conf.sas_direct.example
/etc/zfs/vdev_id.conf.sas_switch.example

Closes#981
To streamline testing I have in the past added several custom configs
to the zpool-config directory. This change reverts those custom configs
and replaces them with three generic config which can do the same thing.
The generic config behavior can be set by setting various environment
variables when calling either the zpool-create.sh or zpios.sh scripts.
For example if you wanted to create and test a single 4-disk Raid-Z2
configuration using disks [A-D]1 with dedicated ZIL and L2ARC devices
you could run the following.
$ ZIL="log A2" L2ARC="cache B2" RANKS=1 CHANNELS=4 LEVEL=2 \
zpool-create.sh -c zpool-raidz
$ zpool status tank
pool: tank
state: ONLINE
scan: none requested
config:
