Decouple Bob's EventLoop from the builder
Instead of instantiating the `EventLoop` within the builder, we only
pass in the necessary arguments (which is the `EventLoopHandle`) to
the Builder upon `new`.

This is work towards #255 which will require us to perform network
communication (which implies having the `EventLoop`) before starting
a swap.

Don't unnecessarily create async blocks
If our expression directly evaluates to a future, we don't need to
create an async block.

This requires us to have `EventLoopRun::run` consume the instance
instead of just taking a mutable reference (otherwise we run into
lifetime issues). However, that is better anyway because `run` is
an endless loop so you never get to use the handle afterwards
anyway.

Reduce logging when signing transactions
1. We can generalize the signing interface by passing a PSBT in
instead of the `TxLock` transaction.
2. Knowing the transaction ID of a transaction that we are about
to sign is not very useful. Instead, it is much more useful to know
what failed. Hence we add a `.context` to the call of `sign_and_finalize`.
3. In case the signing succeeds, we will immediately broadcast it
afterwards. The new broadcasting interface will tell us that we broadcasted
the "lock" transaction.

Unify logging of broadcasted transactions
We eliminate unnecessary layers of indirection for broadcasting logic
and force our callers to provide us with the `kind` of transaction
that we are publishing.

Eventually, we can replace this string with some type-system magic
we can derive the name from the actual transaction. For now, we just
require the caller to duplicate this information because it is faster
and good enough TM.

Shorten function name
This struct is a wallet. The only thing it can meaningfully broadcast
are transactions. The fact that they have to be signed for that is
implied. You cannot broadcast unsigned transactions.

Remove traits in favor of using the wallet struct directly
Abstracting over the individual bits of functionality of the wallet
does have its place, especially if one wants to keep a separation
of an abstract protocol library that other people can use with their
own wallets.

However, at the moment, the traits only cause unnecessary friction.
We can always add such abstraction layers again once we need them.

Only show _log_ output if the user passes --debug
If the user doesn't pass `--debug`, we only show `INFO` logs but
without time and level to make it clearer that it is meant to be

Without `--debug`, the user sees:

bb1537d6f2 Error feedback for the user upon communication errors
If communication with the other party fails the program should stop and the user should see the respective error.
Communication errors are handled in the event-loop. Upon a communication error the event loop is stopped.
Since the event loop is only stopped upon error the Result returned from the event loop is Infallible.

If one of the two futures, event loop and swap,  finishes (success/failure) the other future should be stopped as well.
We use tokio::selec! to stop either future if the other stops.

Remove --send-btc in favor of swapping the available balance
If the current balance is 0, we wait until the user deposits money
to the given address. After that, we simply swap the full balance.

Not only does this simplify the interface by removing a parameter,
but it also integrates the `deposit` command into the `buy-xmr`
command.

Syncing a wallet that is backed by electrum includes transactions
that are part of the mempool when computing the balance.
As such, waiting for a deposit is a very quick action because it
allows us to build our lock transaction on top of the yet to be
confirmed deposit transactions.

This patch introduces another function to the `bitcoin::Wallet` that
relies on the currently statically encoded fee rate. To make sure
future developers don't forget to adjust both, we extract a function
that "selects" a fee rate and return the constant from there.

Fixes #196.

Looking at the rest of the codebase, we don't really seem to follow

As such, these types are just noise and might as well be removed in
favor of simplicity.

1404057dbe Remove misleading TODO
This TDOO is misleading, because - to our current knowledge - it is impossible for
Bob to retrieve the exact inclusion block-height of the lock transaction (send by Alice).
The wallet RPC is only capable of retrieving the inclusion block height of a transaction
through `get_payments` and `get_bulk_payments` which requires the `payment_id`.
The `payment_id` can be retrieved through `get_transfer_by_txid` which states
"Show information about a transfer to/from this address." - however the address that the
transfer goes to is not part of Bob's wallet yet! Thus, it is impossible for Bob to use
`get_transfer_by_txid` which in turn means Bob is unable to use `get_payments`.

The only possible way for Bob to know the exact inclusion block/height of the lock transaction
would be if Alice sends it over to Bob. But for that Alice would have to extract it she would have
to wait for confirmation - which she currently does not and might never do. Even if she does await
the first confirmation before sending the transfer proof the solution for retrieving the inclusion
block-height is not fleshed out on her side yet.

9f1deb9fdc Wrap the Monero wallet client in a Mutex
In order to ensure that we can atomically generate_from_keys and then reload a wallet,
we have to wrap the client of the monero wallet RPC inside a mutex.
When introducing the Mutex I noticed that several inner RPC calls were leaking to the
swap crate monero wallet. As this is a violation of boundaries I introduced the traits
`GetAddress`, `WalletBlockHeight` and `Refresh`.

Note that the monero wallet could potentially know its own public view key and
public spend key. If we refactor the wallet to include this information upon wallet
creation we can also generate addresses using `monero::Address::standard`.

- Upgrading bitcoin-harness to rust-bitcoin 0.26 (https://github.com/coblox/bitcoin-harness-rs/pull/21)
- Upgrade `ecdsa_fun` to latest version
- Replace `cross_curve_dleq` with `sigma_fun` (to avoid an upgrade dance on that library)

I refrained from specifying `rev`s in the Cargo.toml because we have a lock-file anyway. This should allow us to update those dependencies easier in the future by just running `cargo update -p <dependency>`.

164de3c524 Properly calculate the confirmations for Bitcoin tx
Once the transaction was included into a block it has one confirmation - before inclusion it has zero.
current-block-height - transaction-block-height = zero; but that means one confirmation.
Hence, the confirmation calculation was adapted to: Current-block-height - (transaction-block-height - 1).

200: Wait for refund if insufficient Monero is locked up r=da-kami a=da-kami

In a scenario where Alice does not lock up sufficient funds Bob should properly transition to refunds. At the moment the CLI just panics. 
I noticed this when Alice accidentally had a different amount set than Bob. In the future this should not happen, because Alice provides the amount for Bob. However, in case Alice is malicious Bob should still transition correctly.

a0ef1f96ec Replace bitcoind wallet with bdk wallet
The bitcoind wallet required the user to run a bitcoind node. It was replaced with a bdk wallet which allows the user to connect to an electrum instance hosted remotely. An electrum and bitcoind testcontainer were created to the test the bdk wallet. The electrum container reads the blockdata from the bitcoind testcontainer through a shared volume. bitcoind-harness was removed as bitcoind initialisation code was moved into test_utils. The bdk wallet differs from the bitcoind wallet in that it needs to be manually synced with an electrum node. We synchronise the wallet once upon initialisation to prevent a potentially long running blocking task from interrupting protocol execution. The electrum HTTP API was used to get the latest block height and the transaction block height as this functionality was not present in the bdk wallet API or it required the bdk wallet to be re-synced to get an up to date value.

Remove acknowledgements processing
We are aware of issues of timeouts when waiting for acknowledgements.
Also, to properly supports acks in a multiple swap context, we need to
revert to doing event processing on the behaviour so that we can link
leverage the `RequestResponse` libp2p behaviour and link the messages
requests ids to swap ids when receiving an ack or response.

Acks are usefully for specific scenarios where we queue a message on the
behaviour to be sent, save as sent in the DB but crash before the
message is actually sent. With acks we are able to resume the swap,
without ack, the swap will abort (refund).

Before this change, the `EventLoop` would have to hold the path to the

With this change, we can open the DB once and then hold a
`Arc<Database>` in the `EventLoop` and pass it to new `Swap`s structs.

Rename bob::Message2 to Message5
As per the proposed changed in the sequence diagram.
The aim is to have a unique terminology per message instead of having
the same name for 2 consequent messages that share the same behaviour.

Note that the aim is to remove the shared `RequestResponse` behaviours.
