Andreas Straub 3458f5bb91 Clean up logging
Add a fixed prefix to axolotl-related log messages, set log levels
sensibly.

Andreas Straub 7049904c32 Add basic PEP managemend UI to EditAccountActivity
EditAccountActivity now show own fingerprint, and gives an option to
regenerate local keying material (and wipe all sessions associated with
the old keys in the process).

It also now displays a list of other own devices, and gives an option to
remove all but the current device.

Andreas Straub 968410ae33 Fix devicelist update handling
No longer store own device ID (so that we don't encrypt messages for
ourselves), verify that own device ID is present in update list
(otherwise republish), reflect update in UI.

Andreas Straub 0cf64857cf Only cache session if successfully established
When receiving a message, only remember the XmppAxolotlSession wrapper
if the prospective session was actually established. This prevents us
from erroneously adding empty sessions that are never established using
received PreKeyWhisperMessages, which would lead to errors if we try to
use them for sending.

Andreas Straub 25450bf6d3 Trust all IdentityKeys
The trust-on-first-use policy leads to problems when receiving messages
from two different devices of a contact before sending a message to them
(as their IdentityKeys will not have been added yet). Since session
trust will be managed externally anyway, this change is not a security
problem, and will allow us to decrypt messages from yet-untrusted
sessions.

Andreas Straub bf4185ac08 Refresh PEP on session establish
We now track preKeys used to establish incoming sessions with us. On
each new established session, we remove the used prekey from PEP. We
have to do this because libaxolotl-java internally clears the used
preKey from its storage, so we will not be able to establish any future
sessions using that key.

Andreas Straub 69600502d2 Fix asynchronous axolotl message sending
XmppConnectionService.sendMessage() now dispatches messages to the
AxolotlService, where they only are prepared for sending and cached.
AxolotlService now triggers a XmppConnectionService.resendMessage(),
which then handles sending the cached message packet.

This transparently fixes, e.g., handling of messages sent while we are
offline.

Andreas Straub ec6870307e Properly track message sender
Previously, the sender was assumed to be the conversation counterpart.
This broke carboned own-device messages. We now track the sender
properly, and also set the status (sent by one of the own devices vs
received from the counterpart) accordingly.

Andreas Straub 18c1e15d00 Rework PEP content verification
Now checks which part(s) are out of sync w/ local storage, and updates
only those, rather than assuming the entire node corrupt and
overwriting it all (especially relevant for preKey list)

Andreas Straub 992cf5652e When receiving, add mock session if none exists
We need a session object in order to build a session from a
PreKeyWhisperMessage, so add an empty one when none exists on receiving
a message.

Warning: this will break right now if the session can not be constructed
from the received message.There will be an invalid session which will
break if we try to send using it.

Andreas Straub 1b0596d574 Tag messages with originating session
This can be used later in order to display trust status of messages, as
well as for potential resending of messages in case of preKey conflicts.

Andreas Straub 3815d4efa3 Fetch bundles on-demand, encrypt in background
Bundles are now fetched on demand when a session needs to be
established. This should lessen the chance of changes to the bundles
occuring before they're used, as well as lessen the load of fetching
bundles.

Also, the message encryption is now done in a background thread, as this
can be somewhat costly if many sessions are present. This is probably
not going to be an issue in real use, but it's good practice anyway.
