------- Additional Comments from Dumitru Daniliuc <dumi at chromium.org>
It's OK to have DatabaseTracker.cpp depend on
OriginQuotaManager/OriginUsageRecord since we will have a Chromium-specific
implementation for DatabaseTracker.

Also, in order to keep everything thread-safe, we needed to introduce a
SecurityOrigin copy for each Database instance, that is safe to use on the DB
thread.
