use parcel intermediate format for ConversationInfo

Instead of passing ConversationInfo/MessageInfo around as
Strings from provider->UI, use Cursor's blob functionality where
the blob is the marshalled form of the parceled Info objects.

This should be a acceptable use of Parcel, given that we are not
persisting this form, and it only exists to facilitate
provider/UI communication through the generic Cursor interface.

Parcel blobs are fast, well-tested, and do not require
input sanitization.

Traceview testing reveals pretty good gains in Conversation
construction (29% faster on Nexus 7), which is most of the work
in getView().
