List information about block devices in the FreeBSD system.

I often need(ed) to work with Linux systems - and there is `lsblk(8)` command.

Anything closest to it (but still far away) in FreeBSD land are:

```
# geom disk list
# camcontrol devlist
# gpart show
# mount
# zfs list
```

... and none of these tools provide complete information like `lsblk(8)` does.

So I wrote `lsblk(8)` in POSIX `/bin/sh` for FreeBSD.

It only supports two modes.

The default one w/o any arguments.

Listing entire disks with `-d` option.

Hope that helps.

Below you will see examples of **lsblk(8)** usage.

For comparison - this is how Linux version of `lsblk(8)` output looks like.

```
[root@rhidm ~]# lsblk
NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
vda           252:0    0   20G  0 disk
├─vda1        252:1    0  600M  0 part /boot/efi
├─vda2        252:2    0    1G  0 part /boot
└─vda3        252:3    0 18.4G  0 part
  ├─rhel-root 253:0    0 16.4G  0 lvm  /
  └─rhel-swap 253:1    0    2G  0 lvm  [SWAP]

[root@rhidm ~]# lsblk -d
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda  252:0    0  20G  0 disk

```

... and mine `lsblk(8)` on FreeBSD system.

```
