Log Message:
Add support for specifiying attribute dependencies on attributes.  This
allows for the following:

define foo
define bar { }: foo

device foobar: bar

An instance of "foobar" will select "bar", which will in turn select
"foo" due to "bar"'s dependency on "foo".

Circular dependencies are not allowed, and a dependency may also not
be an interface attribute.
