Avoid problems when re-ordering / changing Bob's states
Make it explicit in which states we are able NOT to cancel/refund.

next_state loop always exits in final state
Otherwise we can run into scenarios where the loop never properly exits.

Save Alice's peer-id in the db for Bob
This allows loading the seller-peer-id from the database upon resuming a swap.
Thus, the parameters `--seller-peer-id` is removed for the `resume` command.
Other than the peer-id the multi address of a seller can change and thus is
still a parameter. This parameter might become optional once we add DHT support.

Await 10 confirmations of lock tx in refund
Awaiting the confirmations in an earlier state can cause trouble with resuming
swaps with short cancel expiries (test scenarios).
Since it is the responsibility of the refund state to ensure that the XMR can
be sweeped, we now ensure that the lock transaction has 10 confirmations before
refunding the XMR using generate_from_keys.

Wait for lock tx and send transfer proof in separate state
Sending the transfer transaction in a distinct state helps ensuring
that we do not send the Monero lock transaction twice in a restart
scenario.
Waiting for the first transaction confirmation in a separate state
helps ensuring that we send the transfer proof in a restart scenario.

Alice aborts if any timelock expired before locking XMR
Once we resume unfinished swaps upon startup we have to ensure that
it is safe for Alice to act.
If Bob has locked BTC it is only make sense for Alice to lock up the
XMR as long as no timelock has expired. Hence we abort if the BTC is
locked, but any timelock expired already.

Alice to validate Bob's PSBT for correctness
In order for the re-construction of TxLock to be meaningful, we limit
`Message2` to the PSBT instead of the full struct. This is a breaking
change in the network layer.

The PSBT is valid if:

- It has at most two outputs (we allow a change output)
- One of the outputs pays the agreed upon amount to a shared output script

Resolves #260.

Split bitcoin::Wallet functions into various impl blocks
This allows us to construct instances of bitcoin::Wallet for test
purposes that use a different blockchain and database implementation.

We also parameterize the electrum-client to make it possible to
construct a bitcoin::Wallet for tests that doesn't have one. This
is necessary because the client validates the connection as it is
constructed and we don't want to provide an Electrum backend for
unit tests.

Move messages into protocol module
This allows us to remove all visibility modifiers from the message
fields because child modules (in this case {alice,bob}::state) can
always access private fields of structs.

It also moves the messages into a more natural place. Previously,
they were defined within the network layer even though they are
independent of the libp2p implementation.

Make as many fields of Alice's states private as possible
To achieve this, we need to add some pure helpers to the state structs.
This has the added benefit that we can reduce the amount of code within
the swap function.

86f312e143 Safely abort swap if TxLock is not confirmed in a reasonable time
If TxLock does not confirm in a reasonable amount of time, Alice should
give up on the swap rather than waiting forever. Watching for TxLock in
the mempool is not required and it causes unnecessary complexity. What
if Alice does not see the transaction in mempool but it is already
confirmed? She will abort the swap for no reason.

Introduce a more flexible transaction subscription system
Instead of watching for status changes directly on bitcoin::Wallet,
we return a Subscription object back to the caller. This subscription
object can be re-used multiple times.

Among other things, this now allows callers of `broadcast` to decide
on what to wait for given the returned Subscription object.

The new API is also more concise which allows us to remove some of
the functions on the actor states in favor of simple inline calls.

It sits on top of several refactoring commits that happened while I was debugging why things didn't work as expected. Turned out to be reasonably useful so I just left them in :)

Improve resilience of balance assertions
Sometimes, a single sync is not enough because we are still waiting
for the block to be mined.

We introduce an abstraction that loops on fetching the latest balance

bc902ea63a Use language agnostic heuristic to check if monero_wallet_rpc is ready
Our strategy of searching for a english string to determine if
monero_wallet_rpc is ready is not compatible with languages other than
english. Instead we assume the monero rpc is ready if it has stopped
writing to stdout. We make a json rpc request to confirm this. A better
solution would have been to configure the monero_wallet_rpc to always
output in english but there is not command line argument to configure
the language.

Closes #353.

Buffer transfer proof if we are not connected to Bob
The request-response behaviour that is used for sending the transfer
proof actually has a functionality for buffering a message if we
are currently not connected. However, the request-response behaviour
also emits a dial attempt and **drops** all buffered messages if this
dial attempt fails. For us, the dial attempt will very likely always
fail because Bob is very likely behind NAT and we have to wait for
him to reconnect to us.

To mitigate this, we build our own buffer within the EventLoop and
send transfer proofs as soon as we are connected again.

Resolves #348.

Remove connection handling from swap execution
The swap should not be concerned with connection handling. This is
the responsibility of the overall application.

All but the execution-setup NetworkBehaviour are `request-response`
behaviours. These have built-in functionality to automatically emit
a dial attempt in case we are not connected at the time we want to
send a message. We remove all of the manual dialling code from the
swap in favor of this behaviour.

Additionally, we make sure to establish a connection as soon as the
EventLoop gets started. In case we ever loose the connection to Alice,
we try to re-establish it.

319: Alice sweeps refunded funds into default wallet r=da-kami a=da-kami

Alice's refund scenario starts with generating the temporary wallet
from keys to claim the XMR which results in Alice' unloading the wallet.
Alice then loads her original wallet to be able to handle more swaps.
Since Alice is in the role of the long running daemon handling concurrent
swaps, the operation to close, claim and re-open her default wallet must
be atomic.
This PR adds an additional step, that sweeps all the refunded XMR back into
the default wallet. In order to ensure that this is possible, Alice has to
ensure that the locked XMR got enough confirmations.
These changes allow us to assert Alice's balance after refunding.

62079fc342 Punish scenario falls back to refund or fails
If we enter a punish scenario we can be sure the punish timelock is expired.
Thus, we must be able to punish unless Bob published the refund transaction.
There is no benefit in racing punish against refund here, because we cannot recover from a punish tx failure anyway.

The logic was changed to:
Try to broadcast punish tx and await finality.
  If either punish broadcasting of finality fails, try to fetch the refund transaction.
    If it is available extract Bob's Monero key part and transition to refund.
    If refund tx is not available fail without a status update.

Note that we do not distinguish different errors upon failure of punish, because
we cannot recover anyway. If we fail to retrieve Bob's refund tx, we just exit without
a status update so punish can be retried by resuming the swap.

Simplify code within BobState::XmrLockProofReceived
To achieve this, we decompose `watch_for_locked_xmr` into two parts:

1. A non-self-consuming function to construct a `WatchRequest`
2. A state transition that can now consume `self` again because
it is only called once within the whole select! expression.

Ideally, we would move more logic onto this state transition (like
comparing the actual amounts and fail the transition if it is not
valid). Doing so would have an unfortunate side-effect: We would
always wait for the full confirmations before checking whether or
not we actually receive enough XMR.

This allows us to have state transitions that consume self.

332: Bump base64 from 0.12.3 to 0.13.0 r=thomaseizinger a=dependabot[bot]

Bumps [base64](https://github.com/marshallpierce/rust-base64) from 0.12.3 to 0.13.0.
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a href="https://github.com/marshallpierce/rust-base64/blob/master/RELEASE-NOTES.md">base64's changelog</a>.</em></p>
<blockquote>
<h1>0.13.0</h1>
<ul>
<li>Config methods are const</li>
<li>Added <code>EncoderStringWriter</code> to allow encoding directly to a String</li>
<li><code>EncoderWriter</code> now owns its delegate writer rather than keeping a reference to it (though refs still work)
<ul>
<li>As a consequence, it is now possible to extract the delegate writer from an <code>EncoderWriter</code> via <code>finish()</code>, which returns <code>Result&lt;W&gt;</code> instead of <code>Result&lt;()&gt;</code>. If you were calling <code>finish()</code> explicitly, you will now need to use <code>let _ = foo.finish()</code> instead of just <code>foo.finish()</code> to avoid a warning about the unused value.</li>
</ul>
</li>
<li>When decoding input that has both an invalid length and an invalid symbol as the last byte, <code>InvalidByte</code> will be emitted instead of <code>InvalidLength</code> to make the problem more obvious.</li>
</ul>
<h1>0.12.2</h1>
<ul>
<li>Add <code>BinHex</code> alphabet</li>
</ul>
<h1>0.12.1</h1>
<ul>
<li>Add <code>Bcrypt</code> alphabet</li>
</ul>
<h1>0.12.0</h1>
<ul>
<li>A <code>Read</code> implementation (<code>DecoderReader</code>) to let users transparently decoded data from a b64 input source</li>
<li>IMAP's modified b64 alphabet</li>
<li>Relaxed type restrictions to just <code>AsRef&lt;[ut8]&gt;</code> for main <code>encode*</code>/<code>decode*</code> functions</li>
<li>A minor performance improvement in encoding</li>
</ul>
<h1>0.11.0</h1>
<ul>
<li>Minimum rust version 1.34.0</li>
<li><code>no_std</code> is now supported via the two new features <code>alloc</code> and <code>std</code>.</li>
</ul>
<h1>0.10.1</h1>
<ul>
<li>Minimum rust version 1.27.2</li>
<li>Fix bug in streaming encoding (<a href="https://github.com/marshallpierce/rust-base64/pull/90">#90</a>): if the underlying writer didn't write all the bytes given to it, the remaining bytes would not be retried later. See the docs on <code>EncoderWriter::write</code>.</li>
<li>Make it configurable whether or not to return an error when decoding detects excess trailing bits.</li>
</ul>
<h1>0.10.0</h1>
<ul>
<li>Remove line wrapping. Line wrapping was never a great conceptual fit in this library, and other features (streaming encoding, etc) either couldn't support it or could support only special cases of it with a great increase in complexity. Line wrapping has been pulled out into a <a href="https://crates.io/crates/line-wrap">line-wrap</a> crate, so it's still available if you need it.
<ul>
<li><code>Base64Display</code> creation no longer uses a <code>Result</code> because it can't fail, which means its helper methods for common
configs that <code>unwrap()</code> for you are no longer needed</li>
</ul>
</li>
<li>Add a streaming encoder <code>Write</code> impl to transparently base64 as you write.</li>
<li>Remove the remaining <code>unsafe</code> code.</li>
<li>Remove whitespace stripping to simplify <code>no_std</code> support. No out of the box configs use it, and it's trivial to do yourself if needed: <code>filter(|b| !b&quot; \n\t\r\x0b\x0c&quot;.contains(b)</code>.</li>
<li>Detect invalid trailing symbols when decoding and return an error rather than silently ignoring them.</li>
</ul>
<h1>0.9.3</h1>
<ul>
<li>Update safemem</li>
</ul>
<h1>0.9.2</h1>
<ul>
<li>Derive <code>Clone</code> for <code>DecodeError</code>.</li>
</ul>

321: Properly handle concurrent messages to and from peers r=thomaseizinger a=thomaseizinger

Previously, we were forwarding incoming messages from peers to all

Make Monero and Bitcoin wallet use a generalized sync interval
We define the sync interval as 1/10th of the blocktime. For the
special case of our tests, we however check at max once per second.
The tests have a super fast blocktime. As such we shouldn't hammer
the nodes with a request every 100ms.

8675d88727 Don't wait for tx lock confirmed after broadcast
Bob does not care whether tx lock is confirmed. That is alice's problem.
This wait was introduced to remedy a bug in status_of_script() which was
 failing when called on a transaction with no confirmations.

320: Fix env filter for asb r=thomaseizinger a=thomaseizinger

1. The asb didn't log any if the statements within main.rs
2. We were initializing unnecessary filters that don't make any sense
for the asb. warp and http are not used and the harness-es are for
test only.

317: Fix monero refresh interval r=thomaseizinger a=thomaseizinger

The comparison should be the MAXIMUM of the two values, not the
minimum, otherwise we always refresh at an interval of 1 second.

Disable timestamp if we log to a non-interactive terminal
A non-interactive terminal is likely something along the lines of
journalctl which captures a timestamp by itself. In theory, it could
also be just a logfile but we rather accept this limitation and keep
the configuration surface simple rather than exposing another config
switch.
