commit a149413f0faac240b030d995a7832023d63714f9
Author: Marc Treib <treib@chromium.org>

Remove launched SyncUserConsentSeparateType feature

plus a lot of now-dead code :)
Many tests explicitly disabled the feature. Some of those could be
adapted, some other simply don't apply anymore and were deleted.
