Only load the most recent messages when initially rendering a
conversation. Scrolling to the top of a message list loads older
messages.
This required some slight refactoring of how we insert message elements
into the dom. If the message is added to the end of the collection,
append it at the end. Otherwise, assume it is an older message and
prepend it.
When adding elements to the top, reset the scrollPosition to its
previous distance from scrollHeight. This keeps the current set of
elements fixed in the viewport.

Create a cleaner seperation between generating notifications
and updating frontend conversation views. The former is now
handled by `conversation.notify` while the latter is achieved
by triggering an event on the conversation model, which will
only be acted on if there are any views listening for it.
Additionally, instead of re-fetching the entire message history,
which is overkill, just add or update the new/modified message.
This will help speed up the newmessage event handler and also
help avoid unnecessary re-rendering when resolving key conflicts.

Follow up to ddd2e67eb5
but for incoming messages.
* Conflict state sometimes failed to be removed even though the
conflict was resolved.
* Messages failed to re-render after a conflict. We want to
re-render only the error state on outgoing messages, to avoid
flickering attachments. On incoming messages, we need to call
render to populate the message text, avatar, etc...
// FREEBIE
Previously, with a mix of text and media messages in conflict,
asynchronous callbacks aligned so as to fail to remove some of
the conflict objects on messages.
Fix by serializing conflict processing, but making sure to move
on through the message list even if some conflict resolutions fail.

// FREEBIE
For non text messages (ex: media messages and group updates), the
lastMessage field was being populated with empty string, resulting in an
empty message preview in the conversation list. Instead, display 'Media
message' or 'Updated the group', etc...
// FREEBIE
An exception to the previous commit, for incoming messages we should not
show a mysterious empty bubble. Instead there is some generic
non-technical error message.
// FREEBIE
Change how message errors are rendered. Errors associated with a number
will be shown under that number in the detail view rather than piling up
in the message bubble.
// FREEBIE
Fix inconsistency in error format, where we sometimes get an unexpected
Error object and sometimes get a wrapper object containing an Error.
Also start saving network errors.
// FREEBIE
Refactor outgoing message error handling to use the same success and
error handlers. This creates a somewhat strange pattern, where we call
send and pass in the promise that resolves when sending is complete, but
there's enough variety in the libtextsecure syntax for different message
sending routines that it belongs at the conversation level and only the
post-processing stuff is really shared by all messages.
// FREEBIE
The conversation's contactCollection only contains references to the
current membership, and will not provide contact info for people who
have left the group, causing their messages to render without numbers or
avatars.
// FREEBIE
Only allow one notification at a time. Use a basic notification for
normal messages, and image notification for image messages, and a list
notification when there are multiple unread messages.
// FREEBIE
This trigger function uses chrome's runtime message passing api, which
traverses between different windows in our runtime, but we only trigger
the updateInbox event from the backgroud page, so we don't need to use
that api, which requires some extra cpu/memory overhead.

This bug was caused by a race between indexeddb requests and sending
messages. Order of events to repro was roughly:
1. send async idb request for current message list
2. add new message(s)
3. idb request returns with now incomplete message list
4. message collection gets reset to list from 3, removing messages
added in 2, but not removing their phantom views/dom elements. (bug)
5. send another idb request for current message list
6. idb request returns bearing all messages including those from 2.
7. messages from 2 are added and rendered a second time.
The fix was simply to not remove messages in 4, which means we reuse the
original message model object rather than recreating it in 7.

Update protobuf definitions and refactor message receive and decrypt
codepath to support new protocol, including various flavors of sync
messages (sent messages, contacts, and groups).
Also cleans up background.js and lets libtextsecure internalize
textsecure.processDecrypted and ensure that it is called before handing
DataMessages off to the application.
The Envelope structure now has a generic content field and a
legacyMessage field for backwards compatibility. We'll send outgoing
messages as legacy messages, and sync messages as "content" while
continuing to support both legacy and non-legacy messages on the receive
side until old clients have a chance to transition.
In a multi device world, it's possible to receive a receipt for a sync
message before the sync message actually arrives. In this case we need
to keep the receipt around and the process it when the message shows up.
