Add lsmtd program

This patch adds a program called "lsmtd". The program produces a pretty
printed list of the hierarchy of UBI and MTD devices on a system. It
tries to imitate the lsblk program from util-linux as closely as
possible.

A number of command line switches are available to fine tune what information
should be exposed and in what output format.

The goal is to have a simple way of displaying the complete MTD stack on
a system in a human readable form instead of piecing details together
from proc files and various UBI utilities.
