Revert ubi-tools changes
Restore ubi tools to their "original" state, which means to the state they were before I stareted cleaning them up. Instead, create a "new-utils" subdirectory and move my work there. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

- * 1.0 Reworked the userinterface to use argp.
