This change adds support for a richer API supporting social status
updates.
The new API supports providing multiple status updates (stream items)
to be associated with a single raw contact, and for multiple photos
(stream item photos) to be associated with each stream item. A
limited number of stream items will be stored - callers can query for
the limit to optimize calls. Any inserts beyond the limit will
result in expiration of the oldest item.
