Brad Jorsch beab6b009e Change API result data structure to be cleaner in new formats
Nothing in this patch should result in changed output for format=json or
format=php except as noted in RELEASE-NOTES-1.25, and changed output for
format=xml should be similar or cosmetic. However, other code accessing
the result data directly may need to be updated.
