To allow `rad sync` to break early from the call to `announce`,
control flow is introduced for the callback.
In `rad sync`, the number of synced nodes is checked against the
`replicas` -- if specified -- and sends a `Break`.

This test is flakey and requires further investigation. Some extra
assertions are added to ensure that the expected behaviour is
happening upon fetching. It is unknown if the fetch queue is behaving
properly, and it's suspected that some existing fetch results might be
used for queued fetches.

Previously, we might ban a node if we're having trouble connecting to
it, but this could be due to internet connectivity issues.
We introduce a penalty score for nodes, that increases if there are
connection issues or the node misbehaves, and decreases on successful
connections.
When connected to new nodes, we sort them so that low-penalty nodes are
attempted first.
Instead of having a routing database, and an addresses database,
consolidate that in a single database called `node.db`.
We also simplify database access, by providing a single type for opening
the database, and use traits to access the various functions.
We create a new `seed::Store` that has seed-related methods split out of
the `address::Store`.
Note that tracking is still in its own database currently, as it isn't
ephemeral state. This makes it easy to delete the new `node.db` without
risk of losing any important information.
To avoid renaming all database methods, we create a `Stores` wrapper
that allows us to access routing, addresses, seeds etc. without type
ambiguity.
This is a breaking change and requires `addresses.db` and `routing.db`
to be deleted.
Allow the caller of `rad sync` to `--sort-by` the NID, alias, or
status of the seeds.
This prevents random ordering, due to timestamps, in CLI testing.

This command shows the sync status of a repository by consulting the
database via the node.
To make it work, we call into the address store to update the
`repo-sync-status` table when receiving ref announcements that are
relevant to us.
An informational message for the protocol is useful for sending
messages to a node that is not required to be relayed.
This message is introduced by starting with an ACK message for a set
of references being synced. This fixes an issue for announcing to a
node that is already synced, since it can now ACK that it received the
message and replies that it is synced.

It can be useful to return the `RefsAt` that was announced for this
node, for example, to compare it to node events.
Change the `Handle` method to return `RefsAt` so that when it is
called it returns the local node's `RefsAt`.

We improve the API so that error messages can be sent back and are
always expected as potential responses to commands. This means that
`CommandResult` is always the type that is sent for commands.
This includes some breaking changes, for example the default "success"
message is simply `{}` instead of `{"status":"ok"}`.
When a fetch is user-requested, a timeout can be supplied that is passed
down to the worker.
When a fetch is service-requested, a default timeout is used.
This adds functionality so that on `rad sync` and `rad clone`, we
connect to known seeds if necessary, before attempting to fetch.
In passing, some related changes were made:
* The `rad sync` command's arguments were reworked:
`--replicas <count>` can be used to specify a replica count when
fetching
* The `rad patch` command no longer has a `--fetch` option
* It's now possible to tell the node not to automatically connect to
peers in the background
* `AddressBook` is being used underneath `Seeds` to allow for shuffled
iteration
Only return once the connection is established or failed.
It's still not perfect, as several failure scenarios are not handled,
but it's an improvement.
We move the session address to the top-level struct, since it's needed
in a bunch of places. This change is required for the rate-limiting
code that is coming next.
It's easier if we use camel-case everywhere, because some types may be
used on the web as well as on the control socket. This way, all
json-encoded data looks the same.
Instead of using a command name plus arguments, we use a new `Command`
enum that is similar to the one in `radicle_node::service`. This way,
we're able to have more complex commands and parsing is simplified.
This is a fairly substantial change, which adds a new configuration file
to the user's `$RAD_HOME` that includes node configuration, including
the alias, and also makes node aliases required.
When running `rad auth`, the user is now prompted for an alias, which
defaults to `$USER`.
When running `rad self`, the alias is now shown.
If the user runs radicle without a config file, the defaults are loaded,
and `$USER` is used as the alias.
* Return the correct alias from a node announcement, stripping '\0'
bytes.
* Accept `AliasStore` types as references and as owned.
* Store a `null` in the database if the alias received is empty.
Previously, we only sent the announcement when there were external
addresses. But it contains other information like the node alias,
therefore we always send it.
Since the proof-of-work can be expensive to compute everytime, we add
the ability to load the local node announcement from the file system.
We also change the proof-of-work parameters so that they are relaxed
when running in debug mode, instead of when running tests.
Finally, we remove the boolean validation of the PoW. Instead, we store
the work per-node, in the database, to be used in the future in case of
DoS attacks or network congestion.
Previously, only one connection to the node control socket could be
handled at a time. This usually worked fine, but if one connection hangs
for whatever reason, no other process can access the node.
This command announces refs to peers and waits for them to be
in sync.
Adds a subscribe method to `Handle` so that we can get the events
from the seed to allow us to confirm that the configured seeds fetched
from us.
Instead of returning the namespaces that we fetched with,
we return the remotes that were actually fetched from.
This can differ if some trusted peers were not available
on the remote node.
Previously, if that was the case, it would cause errors
since the remotes were looked up and that lookup failed.
With this change, we not only verify the signed refs before
the repository "transfer", but also validate that all refs in the
repo are signed and there is no discrepancy with the signed refs
file.
