Martin Kosek 5768924710 Extend API validator
makeapi script is used to check if ipalib API is consistent with the
known state in API.txt. When the API is changed, major API version
should be updated. However, when new options/arguments/outputs were
added to an ipalib command, `makeapi --validate' call did not capture
this.

This patch fixes this issue and ensures that also the last command
in API.txt is checked (it was not before this patch).
