Notes:
- All the added authors have signed the CLA.
- Updated 2 AUTHORS lines to match the e-mail addresses used for signing the CLA.
- In addition, checked that all authors in the AUTHORS file after this change
  have signed the CLA.
- Whenever it was possible to guess, based on the e-mail address, that the
  contribution was made under a corporate CLA, added the company and the
  wildcard instead of the individual.
