Major storage layer refactoring to set the stage for clean GCM. 1) We now try to hand out cursors at a minimum. There has always been a fairly clean insertion layer that handles encrypting message bodies, but the process of decrypting message bodies has always been less than ideal. Here we introduce a "Reader" interface that will decrypt message bodies when appropriate and return objects that encapsulate record state. No more MessageDisplayHelper. The MmsSmsDatabase interface is also more sane. 2) We finally rid ourselves of the technical debt associated with TextSecure's initial usage of the default SMS DB. In that world, we weren't able to use anything other than the default "Inbox, Outbox, Sent" types to describe a message, and had to overload the message content itself with a set of local "prefixes" to describe what it was (encrypted, asymetric encrypted, remote encrypted, a key exchange, procssed key exchange), and so on. This includes a major schema update that transforms the "type" field into a bitmask that describes everything that used to be encoded in a prefix, and prefixes have been completely eliminated from the system. No more Prefix.java 3) Refactoring of the MultipartMessageHandler code. It's less of a mess, and hopefully more clear as to what's going on. The next step is to remove what we can from SmsTransportDetails and genericize that interface for a GCM equivalent.

Make MMS more asynchronous and consistent with new SMS types. 1) We now delay MMS notifications until a payload is received, or there's an error downloading the payload. This makes group messages more consistent. 2) All "text" parts of an MMS are combined into a second text record, which is stored in the MMS row directly rather than as a distinct part. This allows for immediate text loading, which means there's no chance a ConversationItem will resize. To do this, we need to include MMS in the big DB migration that's already staged for this application update. It's also an "application-level" migration, because we need the MasterSecret to do it. 3) On conversation display, all image-based parts now have their thumbnails loaded asynchronously. This allows for smooth-scrolling. The thumbnails are also scaled more accurately.

Support for multi-device. 1) In addition to the Recipient interface, there is now RecipientDevice. A Recipient can have multiple corresponding RecipientDevices. All addressing is done to a Recipient, but crypto sessions and transport delivery are done to RecipientDevice. 2) The Push transport handles the discovery and session setup of additional Recipient devices. 3) Some internal rejiggering of Groups.

Implement delivery receipts. 1) Support a "receipt" push message type. 2) Identify messages by timestamp. 3) Introduce a JobManager to handle the queue for network dependent jobs.

Better UX handling on identity key mismatches. 1) Migrate from GSON to Jackson everywhere. 2) Add support for storing identity key conflicts on message rows. 3) Add limited support for surfacing identity key conflicts in UI.

Major storage layer refactoring to set the stage for clean GCM. 1) We now try to hand out cursors at a minimum. There has always been a fairly clean insertion layer that handles encrypting message bodies, but the process of decrypting message bodies has always been less than ideal. Here we introduce a "Reader" interface that will decrypt message bodies when appropriate and return objects that encapsulate record state. No more MessageDisplayHelper. The MmsSmsDatabase interface is also more sane. 2) We finally rid ourselves of the technical debt associated with TextSecure's initial usage of the default SMS DB. In that world, we weren't able to use anything other than the default "Inbox, Outbox, Sent" types to describe a message, and had to overload the message content itself with a set of local "prefixes" to describe what it was (encrypted, asymetric encrypted, remote encrypted, a key exchange, procssed key exchange), and so on. This includes a major schema update that transforms the "type" field into a bitmask that describes everything that used to be encoded in a prefix, and prefixes have been completely eliminated from the system. No more Prefix.java 3) Refactoring of the MultipartMessageHandler code. It's less of a mess, and hopefully more clear as to what's going on. The next step is to remove what we can from SmsTransportDetails and genericize that interface for a GCM equivalent.
