Merge "Avoid .transform() NPEs"

Avoid .transform() NPEs

Guava’s Optional::transform doesn’t support null values returned by
the mapping function — it throws a NPE if that happens. java.util’s
Optional::map does support null values and returns an empty Optional.
Combined with the current YANG-based code’s ability to return null,
this means it’s better to use java.util’s method; this patch switches
all YANG-based Optional transforms to java.util.
