These definitions are fairly trivial and only used in the Processor and
ProcessorCore, so I figured there was no harm in grouping them together.  Let me
know if you'd prefer to split them out one per file.

I'm open to suggestions for a better name for this file.

+#include <string>
+#include <vector>

+#include "base/time/time.h"
+#include "sync/base/sync_export.h"
+#include "sync/protocol/sync.pb.h"

+namespace syncer {
+
+struct SYNC_EXPORT_PRIVATE DataTypeState {

This struct might deserve its own file more than the others do, since a lot of
the classes on the processor -> processor core "Connect" path end up needing to
include it.
