Closing the connection upon completing the `swap_setup` protocol caused problems on the ASB side, because the CLI would close the connection before the last message was properly processed. This would result in swaps going into execution on the CLI side, but not on the ASB side.
The CLI ensures an open connection to the ASB over the complete course of a swap. So it does not make much sense to allow a protocol to close the connection (the CLI would immediately redial).
For the Alice we set the initial `KeepAlive` to `10` seconds because Bob is expected to request a spot price in reasonable time after opening a connection on the protocol. Since Tor connections can take some time we set 10 seconds fow now for resilience.
Given that we combined the `spot_price` and the `execution_setup` messaging into one protocol we should allow the protocol to take longer than 60 seconds to complete.
This is especially important for connections over Tor, where messaging can take significantly longer than over clearnet.
I ran some tests with Tor and did not run into issues with the 60 seconds, but we get very close to the timeout, so we better make it more resilient by adding more time.
When swapping on testnet we ran into a problem where the CLI started the swap after sending all messages successfully, but the ASB ran into a `connection closed` error at the end of the `swap_setup` and the swap state machine was never actually triggered.
Flushing and closing the stream on both sides should ensure that we don't run into this problem and both parties gracefully exit the protocol.
Some network and application specific code does not belong in the protocol module and was moved.
Eventloop, recovery and the outside behaviour were moved to the respective application module because they are application specific.
The `swap_setup` was moved into the network module because upon change both sides will have to be changed and should thus stay close together.
Having `spot_price` and `execution_setup` as separate protocols did not bring any advantages, but was problematic because we had to ensure that `execution_setup` would be triggered after `spot_price`. Because of this dependency it is better to combine the protocols into one.
Combining the protocols also allows a refactoring to get rid of the `libp2p-async-await` dependency.
Alice always listens for the `swap_setup` protocol. When Bob opens a substream on that protocol the spot price is communicated, and then all execution setup messages (swap-id and signature exchange).
Includes a new state that is used to await BTC lock tx finality. Upon starting the swap we initially only wait for the BTC lock tx to be seen in the mempool.
This is guarded by a short timeout (3 mins), because it is assumed that in the current setup (sport_price + execution_setup only triggered upon funds being available already) the lock transaction should be picked up almost instanly after the execution setup succeeded.
Similar to the CLI the ASB has to ensure that the execution_setup is executed within a certain time.
Without a timeout the price (returned by `spot_price` would be guaranteed with the CLI indefinitely.
It seems the current chosen channel timeouts are still not optimal.
I ran into issues with swapping over Tor and traced them down to the CLI timeout of the bmrng channel.
It appears that the ASB was not running as quick as the CLI, which caused a timeout on the CLI side (in addition to the delay when sending messages over Tor).
Only `execution_setup` caused the problem so far, but I would recommend changing all the channel timeouts to one minute to avoid this problem.

Instead of splitting up the transports into capabilities, we compose
them directly for each application. This allows us to remove the
websocket transport for the CLI which is really only needed for the
ASB to allow retrieval of quotes via the browser.
Libp2p's transports are meant to be composed. Hence, any form of
fallback should be implemented by emitting `MultiaddrNotSupported`
from the `listen` and `dial` functions.
This allows us to completely remove the tcp transport from the tor
transport.
515: Make it easier to create a bitcoin::Wallet for testing r=thomaseizinger a=thomaseizinger
Forcing the user to create an implementation of `EstimateFeeRate`
every time they want to create a wallet for testing is tedious and
leads to duplicated code.
The implementation for tests is rarely dynamic and thus can be
simplified to static arguments.
This also allows us to provide convenience constructors to make tests
that don't care about fees less distracting by reducing the number of
constants that are floating around.

535: Bitcoin network check when building PSBT r=da-kami a=da-kami
This ensures that funds are not sent to an address on the wrong network.

Forcing the user to create an implementation of `EstimateFeeRate`
every time they want to create a wallet for testing is tedious and
leads to duplicated code.
The implementation for tests is rarely dynamic and thus can be
simplified to static arguments.
This also allows us to provide convenience constructors to make tests
that don't care about fees less distracting by reducing the number of
constants that are floating around.
Adds the ping behaviour to both ASB and CLI behaviour that periodically pings a connected party to ensure that the underlying network connection is still alive.
This fixes problems with long-running connections that become dead without a connection closure being reported back to the swarm.
This will allow us to compile on stable Rust.
The latest version of `secp256kfun` uses `curve25519-dalek-ng` instead
of the original curve25519-dalek crate. Instead of converting back and
forth, we simply switch to this crate as well. Judging from the README
it is just a fork because there was trouble between the maintainers of
the original crate.
It appears to be more stable.
Encountered issues with the previous setup, `monero-wallet-rpc` logs:
```
2021-05-24 04:23:54.852 E !r. THROW EXCEPTION: tools::error::no_connection_to_daemon
2021-05-24 04:23:54.857 E Exception at while refreshing, what=no connection to daemon
```
525: Bitcoin transaction published state r=da-kami a=da-kami
This improves the error handling on the ASB.
Once the Bitcoin redeem transaction is seen in mempool, the state machine cannot transition to a cancel scenario anymore because at that point the CLI will have redeemed the Monero.
The additional state then waits for transaction finality and prevents re-publishing the transaction.
