Add -gLp to zpool subcommands for alt vdev names
The following options have been added to the zpool add, iostat, list, status, and split subcommands. The default behavior was not modified, from zfs(8). -g Display vdev GUIDs instead of the normal short device names. These GUIDs can be used in-place of device names for the zpool detach/off‐ line/remove/replace commands. -L Display real paths for vdevs resolving all symbolic links. This can be used to lookup the current block device name regardless of the /dev/disk/ path used to open it. -p Display full paths for vdevs instead of only the last component of the path. This can be used in conjunction with the -L flag. This behavior may also be enabled using the following environment variables. ZPOOL_VDEV_NAME_GUID ZPOOL_VDEV_NAME_FOLLOW_LINKS ZPOOL_VDEV_NAME_PATH This change is based on worked originally started by Richard Yao to add a -g option. Then extended by @ilovezfs to add a -L option for openzfsonosx. Those changes have been merged, re-factored, a -p option added and extended to all relevant zpool subcommands.
