Provider and DB changes to support data_set field.

The intent of the data set field is to provide a way for multiple
sync adapters from the same account name + type to manage separate
sets of data in the raw_contacts and groups table.

For example, this would allow for Focus groups to be synced in from
Focus via the Google Contacts sync adapter, and for Google+ Circles
to be synced in from the Google+ app, even though both are tied to
the same account name + type.
