Clean up tests
* Broke up ConstantsTest (#280) - the key encoding parts are now in KeyEncodingAndParsingTest, the message encoding parts are in MessageSizeIntegrationTest
* Renamed the other integration tests in briar-android-tests
* Moved the integration tests in briar-android-tests to the top-level package, as they all involve code from multiple packages
* Separated DatabaseExecutorModule from DatabaseModule so we can use a different @DatabaseExecutor in integration tests
* Merged AppModule with AndroidModule (@ernir, this touches code you're working on but I don't think there are any conflicts)
* Renamed some TestUtils methods for consistency
* Used TestUtils.getRandomBytes() where applicable
Fixes#280.

Create local state for clients at startup. #279
Most of the clients we've written so far use private groups shared with individual contacts and/or a local group that's not shared with anyone. To make it easier to ensure that the necessary groups exist when we need them, this patch allows clients to register startup hooks for creating their local state.
Fixes#279.

Don't allow reentrant transactions
The database's transaction lock is reentrant, meaning that a thread that's already holding the lock can acquire it again. This would allow a thread that already has a transaction in progress to start another transaction, which could cause transaction isolation issues and/or lock timeouts on the database's internal locks.
Check that the current thread isn't already holding the lock when starting a transaction.

Contact Introduction Backend
This MR allows you to introduce two of your contacts to each other. They both will receive an introduction with an optional message and then can accept or refuse the introduction which is presented as a notification.
When reviewing, I propose to review the individual commits separately as I took great care to split functional independent parts into separate commits. You might also want to have a look at the [Introduction Client Wiki page](https://code.briarproject.org/akwizgran/briar/wikis/IntroductionClient) to better understand what is going on before looking into the actual code.
Protocol sessions and states are not yet deleted and the UI is still missing (#253). In order to practically test this feature, the UI from !122 is needed.

BQP with QR codes
This MR implements BQP for key agreement over short-range transports. It also implements the Android UI for using BQP with QR codes.
Closes#117.

The database's transaction lock is reentrant, meaning that a thread that's already holding the lock can acquire it again. This would allow a thread that already has a transaction in progress to start another transaction, which could cause transaction isolation issues and/or lock timeouts on the database's internal locks.
Check that the current thread isn't already holding the lock when starting a transaction.
This Introduction BSP Client uses its own group to communicate with
existing contacts. It uses four types of messages to facilitate
introductions: the introduction, the response, the ack and the abort.
The protocol logic is encapsulated in two protocol engines, one for the
introducer and one for the introducee. The introduction client keeps the
local state for each engine, hands messages over to the engines and
processes the result and state changes they return.
This requires exposing the `containsContact()` method to the `DatabaseComponent`
and is needed for finding out efficiently whether a contact already exists.
Message queues. #266
A message queue is a group shared by two devices that delivers messages from each device to the other in order. The first 64 bits of the message body contain a sequence number that's incremented for each message sent in a given direction. The incoming and outgoing sequence numbers and information about any messages received out of order and waiting to be delivered are stored in the group metadata.
