- Change the type of kDefaultParams from vector to array. The tests
  are modified to pass a full list of params accordingly.
- Delete SetResolversWithTls(). Use SetResolversFromParcel() instead.
- Delete makeResolverParamsParcel().
- Replace kDefaultServers with kDefaultServer; replace kDefaultSearchDomain
  with kDefaultSearchDomains
