Relay now has three values: "always", "never" and "auto".
The first two operate like the previous `true`/`false`. The
new (default) value turns relaying on for nodes with public (external)
addresses and off for nodes without. This should reduce redundant traffic on
the network, that was causing the rate limiters to trigger.
With the increase in traffic on the network after launch, the old
defaults don't make sense anymore.
Longer term, we should look into throttling outgoing messages as well,
prioritizing original messages over relayed messages.
If multiple ids are specified for `rad inbox clear`, it would report
that only 1 item was cleared, when in fact multiple were.
This was found to be due to the SQL code returning a change count of
`1`. This is likely due to the way the statement is being reset each
time. The `sqlite` library does not seem to easily support the usage
of `IN` in a `WHERE` clause. So instead, the `count` is aggregated in
the loop and returned instead.

Implement this function on `RemoteRepository`, and move `repositories`
to the trait level.
This function will be used to quickly get the `RefsAt` of all repository
remotes.
When deciding whether or not to fetch a repo based on a refs
announcement, we need to know whether our signed refs are stale or not,
compared to the ones in the announcement. This can be quite expensive as
it requires multiple reads from Git's ODB, which often results in
packfile loading.
To remedy this, we introduce a refs cache in our node database that is
consulted when an announcement is received.
We also remove the logic that generates `info` messages, since they are
rarely needed and introduced more complexity.
Additionally, we revert commit 3ad2b4431f,
which introduced logic to minimze wants and haves with additional logic,
since it potentially also increases the load on the ODB.
When the `rad inbox` command would come across a reference name that
it did not recognise as a `Cob` or `Branch`, then it would fail with
an `Unknown` error.
Instead, add an `Unknown` variant to `NotificationKind` which can be
displayed in the `inbox` CLI, by using the `--show-unknown`
flag. Otherwise, it will be skipped and the inbox will work as usual.
While refactoring, the `TypedId` type is used for the `Cob` variant to
simplify some of its uses.

Previously, authorization was only checked for ops after the root op.
We also avoid creating empty actions for `assign` and `label`, which
was needed for non-authorized users to be able to create issues/patches.
This makes the default policy `block` with scope `all`. The good thing
about this is that you don't have to manage individual nodes in the
beginning. You simply seed the repos you want, and everything is
followed within those repos. This matches user expectations, as `rad
seed` does what you expect it to do.
For open-policy seed nodes, it also means that simply changing `block`
to `allow` from the default config is all you need.
This leaves the non-default `followed` scope as a more "advanced"
setting, since it is much more cumbersome: it forces you to follow a
user before you can see their issues/patches, which is not something
most users expect coming from old-shcool forges.
Shows you updates on local repositories.
Included here is a basic implementation of a notification system. A new
database is created and updated after every fetch, with refs that have
changed.
The `rad inbox` command can then list items in the database and delete
them.
When using `network: "test"`, we shouldn't default to any public seed
node. This change makes sure that the "preferredSeeds" configuration var
is only given a value when `network` is `main`.
Add a `Config` constructor for testing seed nodes that uses
`usize::MAX` for capacity.
This allows test scenarios to not drop messages due to rate limiting
-- all nodes are on the same IP address and rate limiting is performed
per IP address.

By default, this command now:
* Follows the peer if not already followed
* Syncs refs of the peer, if it wasn't followed before
* Fetches refs into working copy
This functionality can be disabled via `--no-sync` and `--no-fetch`.
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.
We create a system for migrating the our databases, as well as a first
migration, for adding a `penalty` field to the `nodes` table, which we
are going to need soon, as an example.
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.
Currently, if refs are updated while the node is stopped, these refs are
not immediately announced when the node starts, due to the node being
unaware of the updates.
To remedy this, on startup, we compare the refs we have in storage with
the refs we announced to the network. Since only our own refs could have
changed while the node was stopped, this change only applies to owned
refs. If we detect that storage has changed while the node was stopped,
we create ref announcements for the updated repos and store them in our
gossip database. These announcements will be included with other
historical gossip announcements when nodes connect to us.
To keep track of what was announced, we store our local node's sync
status in the database. This is also useful when using the `rad sync status`
command, as it tells us what oid our local node is at, and whether it
is aware of our local changes yet.
In addition to this, we make a small fix: previously, inventory and ref
announcements originating from our local node were not stored in the
announcement database. We ensure that they are via the new `announce`
method.
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.
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`.

Previously, we would process any valid inventory or refs announcement.
This could cause problems for keeping sync statuses, as we could get
a refs announcement from a node that isn't in our database.
In practice, there is no good reason why we should receive a refs or
inventory announcement before the announcer's node announcement, unless
nodes are not following the protocol.
Implementing this change meant that many of the tests needed updating,
as it wasn't assumed that a node announcement was needed before
receiving inventories etc. from a peer.
We also had to implement a basic form of node address banning to make
the tests pass after this change.
