Well, as long as we have cyclotom.spad new package must use different
name. Removing package _after_ release gives reasonable transition
period: the old code will work with old versions and new release.
CyclotomicUtilities was added on January 2, so people who build from
reasonably recent sources will get it.
For CyclotomicPolynomialPackage we probably could do rename after
release, but in general removal of old package name is cleaner
