Profile API modifications.

This is a set of changes to allow for splitting off the Profile
concept in the Contacts Provider into a separate database:
- Removed the ALLOW_PROFILE parameter, as it is no longer possible
  to combine profile data with contacts data in a single query.
- Added profile sync state as a separate table.
- Clarified status update API usage to indicate that profile updates
  need to either be done for a specific data ID or using a new
  profile-specific URI.
- Added constant and API for determining whether an ID falls within
  the profile ID-space.
