Implement RcsProvider
This is a provider for internal use to access the RCS database tables.
This change is basically ag/5542367 with the crash fixed. In
RcsProvider, we now don't open the database immediately, instead wait
for it to be necessary to open the database.
Test: Added unit test, also tested manually by setting the flag to true
and seeing the database with the new table.
