Delete bob::negotiate 
This module was intended to contain helper functions for each step.

However, those are not needed except for the negotiate step.
A dedicated module is not needed for one function.

like it is done in the bob module.

Remove passing alice peer id 
The usage of the peer id is incorrect as we do not even check it when
dialing. For now, we can ignore it.
We can then re-introduce it and use it properly at a later stage.

27d1334726 Init Alice behaviour with state0 
Previously state0 had to be set after creating Alice's behaviour.
With the event loop we no longer has access to the swarm so
set_state0() has to be called indirectly through a channel. This
means it is difficult to guarantee state0 is being set due to the
asynchronous nature of channels. This was solved by initialising
Alice with state0.

1a2857af29 Properly init tracing per test and reverse the filter to be exclusive 
Tracing should be initialized by test and the `_guard` kept alive within the test.
Re-using this code in different tests does not really have any additional value.

Instead of specifying what messages we want to include, I went for a filter that excludes noise.
That way we get more useful logging.

Force Bob swarm polling to send message 2

this was the right thing to do, message2 was not being sent as the

28225f8643 Implement swap recover function for Alice 
This introduces a lot of duplication between the binary and the
library, but it's okay because this module should only be a temporary
measure until we allow recovery to be handled by the original state
machine.

Also, fix a bug in `xmr_btc::alice::action_generator` caused by the
incorrect assumption that Alice's ability to punish Bob could be
determined before the cancel transaction hits the blockchain.

796d0b3439 Extract transport creation and remove tor conditional compile 
The numerous tor conditional compile flags were removed by
extracting transport creation to the main statement. A tor
transport is created if Alice specifies a tor port using the CLI.

0ca511bf8a Remove hardcoded configuration 
The hardcoded configuration was replaced with CLI
configuration options. CLI based config was chosen
over a config file as it does not access and clutter
the user's file system. By CLI options depend on whether
the program is run in Alice or Bob mode.

4d4acde476 Bubble up an event when Bob receives message 3 response 
Before this patch Bob is not sending message 3. This is because we are not
polling Bob's swarm correctly. To fix it we can just mimic the other NB's and
bubble up an event when Bob receives message 3 response from Alice, this way we
can `await` upon this event which triggers polling, making Bob's swarm send the
message.

a37f43a1ba wip: Provide enough funds to both parties 
Also use cosntant backoff retry strategy as opposed to exponential
backoff. This is in case retrying several times quickly causes the
retry intervals to become large enough that the test is very slow
and/or the Bitcoin lock transaction expires.

The current problem occurs on the last message i.e. Bob sending
tx_redeem_encsig to Alice. The action is yielded for Bob to do it, but
Alice appears to never receive it (unconfirmed claim, requires more
logging).

3f43581da7 Implement traits Receive{BitcoinRedeemEncsig, TransferProof} 
Unfortunately, I had to put the wrap the swarm in Alice's `Network`
struct in an `Arc<Mutex<T>>` in order to be able to use `backoff` to
control the retry mechanism. This is because the stream of events
cannot be turned into a `SharedFuture` (unlike Bob's).

It would be good to find an alternative solution.

It looks like the compiler can ascertain that `message0` will be
initialised by the time we use it, so it doesn't need to be an
`Option` and it doesn't need to be declared as mutable.

aaf1363c05 Refine peer tracker and amounts protocol 
We model the getting of amounts as a network behaviour even though conceptually
it is a protocol. Refine/refactor the code a bit to make this more obvious.

- Use `Amounts` instead of `Messenger`

We only ever connect to a single peer, update peer tracker to reflect this. This
is a single patch because the handling of the two network behaviours is a
intertwined.

- Only track one peer connection
- Track the peer id and the multiaddr of the counterparty
- Emit an event for connection established on Alice's side as well as Bob's side
