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.
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.
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.
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.
338: Timeout improvements r=rishflab a=rishflab
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 no longer required and 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.

361: Introduce a more flexible transaction subscription system r=rishflab a=thomaseizinger
TODO:
- [x] Make sure we unsubscribe once all receivers are gone. How do we handle repeated subscriptions?
Will squash the last 4 or 5 commits once approved
Co-authored-by: Thomas Eizinger <thomas@eizinger.io>
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.

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
with a certain timeout for asserting the balance.
By using `test_writer`, cargo can automatically scope the output
of the test to the relevant thread and will also only output it
if the test fails or is run with `--nocapture`.
This also formats `log` events more nicely. Instead of
```
Mar 29 09:46:16.775 INFO log: Found message after comparing 82 lines log.target="testcontainers::core::wait_for_message" log.module_path="testcontainers::core::wait_for_message" log.file="/home/thomas/.cargo/registry/src/github.com-1ecc6299db9ec823/testcontainers-0.12.0/src/core/wait_for_message.rs" log.line=35
```
We now have
```

```
366: Asb docs r=da-kami a=da-kami
Note:
There is currently quite a lot ongoing to make the ASB better, so the documentation will naturally get outdated.
Knowing that, I opted for linking to ongoing issues that will improve ASB setup / execution so that users can refer to them to see the progress.
We need documentation to make ASB setup / exec understandable. Let's see to get this in so we have something to iterate on :)

379: Use language agnostic heuristic to check if monero_wallet_rpc is ready r=rishflab a=rishflab
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.
NOTE: will squash after approved

Whenever a release branch - that is a branch starting with `release/` -
is merged into master, we create a new GitHub release based on the
version number in the branch name.
Similarly to the preview release, we extract the relevant section of
the changelog and make it the release body.
Drafting a new release can be quite involved. One has to update the
changelog correctly, bump the versions in the manifest files, commit
everything and raise a PR.
This workflow does all of that for you at the click of a button!
