The "contact" option in the attachments tray now brings you through an
optimized contact sharing flow, allowing you to select specific fields
to share. The contact is then presented as a special message type,
allowing you to interact with the card to add the contact to your system
contacts, invite them to signal, initiate a signal message, etc.
Eliminate the concept of 'Recipients' (plural). There is now just
a 'Recipient', which contains an Address that is either an individual
or a group ID.
MMS groups now exist as part of the group database, just like push
groups.

This was a holdover from Signal's origins as a pure SMS app.
It causes problems, depends on undefined device specific behavior,
and should no longer be necessary now that we have all the
information we need to E164 all numbers.

1) Remove all our PDU code and switch to the PDU code from the
klinker library
2) Switch to using the system Lollipop MMS library by default,
and falling back to our own custom library if that fails.
3) Format SMIL differently, using code from klinker instead of
what we've pieced together.
4) Pull per-carrier MMS media constraints from the XML config
files in the klinker library, instead of hardcoding it at 280kb.
Hopefully this is an improvement, but given that MMS is involved,
it will probably make things worse instead.
1) The group ID for jobs that process received messages was
previously set to the sender's e164. This guaranteed
serialization of messages per-recipient, while allowing
processing of multiple recipients in parallel. Unfortunately
in the case of groups, this results in out of order
conversations, since the "sender" for each message is
different. And we can't determine that it was a group
message until *after* we process it. So this change just
puts all message processing from all senders in one big queue.
2) Synchronization messages were always being displayed before
received messages, due to the "received time" for those
being set to the time they were sent.
