This does not change the API in anyway other than to enforce a
consistent, sorted order for all annotations; sorted by qualified
name of the annotation.
A simple bug in metalava meant that annotations were not sorted on an
API item that had exactly two annotations in the source. Fixing the
bug forced the regeneration of the signature files.
