246: Change anyhow! to bail! in error scenarios r=da-kami a=da-kami
Unfortunately I handled the two failure scenarios in the ASB wrong - I thought that was fixed already, but that was different logic in a different PR.

These intermediate structs were creating unnecessary noise. The peer id
and multiaddr fields are going to be removed in the future further
reducing the need to have seperate structs for cancel, resume and
refund.
239: Remove windows from the release r=da-kami a=da-kami
At the moment windows fails to build. This has to be fixed before it is re-added to the release.

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.
Failure does not express what the error represents. It is only used for communication
errors for quote requests, receiving the XMR transfer proof and sending the encryption signature.
235: monero-rpc debug log for moner-harness tests r=thomaseizinger a=da-kami
This allows us to see the response from the monerod client on debug.
When the monero-harness was split up into harness and rpc this was overlooked.
We need the debug logs to investigate the monero harness CI fail bug.

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.
These traits were only used once within the `TxLock` constructor.
Looking at the rest of the codebase, we don't really seem to follow
any abstractions here where the protocol shouldn't know about the
exact types that is being passed in.
As such, these types are just noise and might as well be removed in
favor of simplicity.
The only reason we need this argument is because we need to access
the output descriptor. We can save that one ahead of time at when
we construct the type.
BDK already has a log line for the sync that we could enable if we
wanted such a log.
Additionally, _we_ are not actually syncing the wallet, bdk is so our
log line was lying. It should have said "calling bdk to sync wallet".
231: Error only on close message when fetching the rate r=thomaseizinger a=da-kami
Ping/Pong messages disturb the rate requests quite frequently resulting in failed swap setup because there is no rate available.
As a result messages Ping, Pong and Binary are now ignored and not reported as error.

This allows us to see the response from the monerod client on debug.
When the monero-harness was split up into harness and rpc this was overlooked.
We need the debug logs to investigate the monero harness CI fail bug.
If the monero wallet rpc has not already been downloaded we download the monero cli package and extract the wallet rpc. The unneeded files are cleaned up. The monero wallet rpc is started on a random port which is provided to the swap cli.
We added a fork of tokio-tar via a git subtree because we needed a tokio-tar version that was compatible with tokio 1.0. Remove this subtree in favor of a regular cargo dependency when this PR merges: https://github.com/vorot93/tokio-tar/pull/3.

For transitioning to state4 we either go into a redeem or a cancellation scenario.
The function name state4 is misleading, because it is only used for cancellation scenarios.
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.
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`.
