Alice chooses the fee for TxPunish because she is the one that cares.
Bob chooses the fee for TxRefund because he is the one that cares.
Note must be taken here because if the fee is too low (e.g. < min tx fee) then she might not be able to publish TxRedeem at all.

434: Introduce monero-wallet crate r=thomaseizinger a=thomaseizinger
This PR:
1. ~Introduce a crate for the epee binary serialization as a serde format~: Released here: https://github.com/comit-network/monero-epee-bin-serde
2. Extends the MoneroRPC client with two binary calls
3. Introduces a `monero-wallet` crate that for now just provides functionality for choosing random key offsets. Together with the the ability to produce bulletproofs and ring signatures, this should be enough for signing Monero transactions locally.
(1) and (2) are a prerequisite for (3).

460: Different default directories for CLI and ASB r=da-kami a=da-kami
Fixes#437
Using the same default directory as data-/config-dir has caused unwanted side effects when running both applications on the same machine.
Use these directory names:
- ASB: `xmr-btc-swap-asb`
- CLI: `xmr-btc-swap-cli`
Since the functionality is now application specific the respective functions were moved into the appropriate module of the application.

459: Use dprint for formatting Cargo.toml files r=thomaseizinger a=thomaseizinger
Invoking cargo tomlfmt on all files is a PITA and as we can see from
the CI scripts, it is often forgotten to as new crates are added to
the workspace.
Using dprint for toml files fixes this.
Unfortunately, we can't use dprint for Rust code yet because there
hasn't been a release of rustfmt in quite a while but we are already
using features from a newer rustfmt via rustup.

Bob validates that incoming transfer proof messages are coming from the peer-id of Alice.
Currently Bob will ignore any transfer proof message that is not coming from the counterparty peer-id associated to the current swap in execution.
Once we add support for trying to save received transfer proofs for swaps that are currently not in execution we can also adapy allowing this for different counterparty peer-ids. This requires access to the database in Bob's event loop.
Alice validates that incoming encsig messages are coming from the peer-id that is associated with the swap.
Encsig message from a peer-id different to the one associated with the swap are ignored.

This PR does a few things.
* It adds a TorTransport which either dials through Tor's socks5 proxy or via clearnet.
* It enables ASB to register hidden services for each network it is listening on. We assume that we only care about different ports and re-use the same onion-address for all of them. The ASB requires to have access to Tor's control port.
* It adds support to dial through a local Tor socks5 proxy. We assume that Tor is always available on localhost. Swap cli only requires Tor to be running so that it can send messages via Tor's socks5 proxy.
* It adds a new e2e test which swaps through Tor. For this we assume that Tor is currently running on localhost. All other tests are running via clear net.
442: Minor cleanups towards implementing a Monero wallet for local signing r=thomaseizinger a=thomaseizinger
Extracted out of #434.
Co-authored-by: Thomas Eizinger <thomas@eizinger.io>
1. Split up image::Monero into Monerod and MoneroWalletRpc
2. Don't use `bash` to run the internal command. Instead we disable
the entrypoint script as per https://github.com/XMRto/monero#raw-commands
3. Remove the start up delay by listening for the correct log message.
To make this more resilient, we make the log level NOT configurable and
instead always log verbosely.
A `RequestResponseCodec` for pull-based protocols where the response is encoded using JSON.
This was added to more properly express the behavior of the quote protocol, where the dialer
doesn't send any message and expects the listener to directly send the response.

- Listen on both tcp and websockets as default
- Listening addresses in config as array
- Configure fallback transport using `or_transport` - if listening on a given address fails on WS, we fall back to TCP.
Instead of forwarding every error, we deliberately ignore certain
variants that are not worth being printed to the log. In particular,
this concerns "UnsupportedProtocols" and "ResponseOmission".
To make this less verbose we introduce a macro for mapping a
`RequestResponseEvent` to `{alice,bob}::OutEvent`. We use a macro
because those `OutEvent`s are different types and the only other
way of abstracting over them would be to introduce traits that we
implement on both of them.
To make the macro easier to use, we move all the `From` implementations
that convert between the protocol and the more high-level behaviour
into the actual protocol module.
405: Concurrent swaps with same peer r=da-kami a=da-kami
Fixes#367
- [x] Concurrent swaps with same peer
Not sure how much more time I should invest into this. We could just merge the current state and then do improvements on top...?
Improvements:
- [x] Think `// TODO: Remove unnecessary swap-id check` through and remove it
- [x] Add concurrent swap test, multiple swaps with same Bob
- [ ] Save swap messages without matching swap in execution in the database
- [ ] Assert the balances in the new concurrent swap tests
- [ ] ~~Add concurrent swap test, multiple swaps with different Bobs~~
- [ ] ~~Send swap-id in separate message, not on top of `Message0`~~

- Swap-id is exchanged during execution setup. CLI (Bob) sends the swap-id to be used in his first message.
- Transfer poof and encryption signature messages include the swap-id so it can be properly associated with the correct swap.
- ASB: Encryption signatures are associated with swaps by swap-id, not peer-id.
- ASB: Transfer proofs are still associated to peer-ids (because they have to be sent to the respective peer), but the ASB can buffer multiple
- CLI: Incoming transfer proofs are checked for matching swap-id. If a transfer proof with a different swap-id than the current executing swap is received it will be ignored. We can change this to saving into the database.
Includes concurrent swap tests with the same Bob.
- One test that pauses and starts an additional swap after the transfer proof was received. Results in both swaps being redeemed after resuming the first swap.
- One test that pauses and starts an additional swap before the transfer proof is sent (just after BTC locked). Results in the second swap redeeming and the first swap being refunded (because the transfer proof on Bob's side is lost). Once we store transfer proofs that we receive during executing a different swap into the database both swaps should redeem.
Note that the monero harness was adapted to allow creating wallets with multiple outputs, which is needed for Alice.
397: Always log at debug level to file r=rishflab a=rishflab
WILL SQUASH DOWN TO 3 COMMITS WHEN APPROVED!
Log at debug level to file
EnvFilter is applied globally. This means you cannot log at INFO level
to the terminal and at DEBUG level to log files. To get a around this
limitation I had to implement the layer trait on a new type and filter
in the on_event() trait method. Each swap has its own log file denoted
by its swap_id. The logger appends to the existing file when resuming a
swap.
Closes#278
I think the `DebugTerminalPritner` and `InfoTerminalPrinter` could be consolidated with some effort with some generics wizardry. It works for now and I think it can be done later. I wish in general there was a cleaner way to do this.
