Instead of resetting the number of attempts on connection, reset it when
the connection is stable, ie. after some time has passed.
This prevents connection retries from happening in succession when a
peer is disconnected during the initial handshake, as is the case with
invalid subscribe timestamps.
If our inventory hasn't updated, don't issue a new inventory
announcement, simply use the previous message.
This avoids identical inventories propagating over the network and using
up resources.
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.
Many (most?) system clocks are not monotonic, and even though we're
getting a `LocalTime`, which *is* monotonic when using `now()`, it is
constructed from a `SystemTime` which isn't.
* Try to use constants instead of strings
* Move crypto seed override out of radicle-crypto
* Use GIT_COMMITTER_DATE for commit overrides
* Use RAD_LOCAL_TIME as general time override
* Allow variables to be used in release mode
There are rare cases where ref announcements may be sent in close
succession, and the current clock time is re-used. This will cause the
second (newer) announcement to be ignored by peers.
We add a `timestamp` method that checks if the timestamp is re-used, and
increments it if so, ensuring that we always use a fresh one.
Since a user can force a fetch of a private repository without any
announcement being involved, we update the routing table if the fetch
completes successfully, with the remote node.
When a `Patch` or `Issue` is entirely removed from the Git repository,
then there is no update to be made -- instead it should also be
removed from the cache.
This covers the case where the original author of the COB deletes the
COB.

There are two areas where we can be more tolerant of delegate namespaces
being missing or not validating:
1. Calculating the canonical HEAD
2. Fetching from a remote
In 1. the protocol is tolerant in that if the local node does not have
the default branch for a delegate, it will still attempt to use any of
the delegates it does have to reach the threshold.
This is made safe by ensuring that if the threshold is being updated
then the node performing the update must have a threshold of delegates
locally in their storage. It also made safe by 2.
In 2. the protocol is tolerant by allowing delegates to be missing
from the serving side, as long as they can still meet a threshold of
delegates. This is further tolerant, when validating the received
data, a threshold of delegates are valid to consider the fetch
successful -- otherwise it will fail.
