This allows change commits to have more than one parent that isn't
part of the DAG.
We can use this to create dependencies towards git objects such as
commits, in the case of patch actions.
Instead of parsing the worker requests and responses, which was causing issues
around packfile transmission, we use threads and pass the bytes
transparently.
Previously we were announcing inventories all the time, due to
relying on the timestamp changing on insertion.
We change this to only announce our inventory when it actually changes.
Previously, during the "transfer" stage of a fetch, we used `force:
false`, which didn't allow refs to be force-updated.
This change makes it possible to fetch force-updated refs, but ensures
that the sigrefs branch is never force-updated.
To improve the reliability and flexibility of the protocol, we introduce
multiplexing over peer connections. This involves a new `Frame` type
that carries a stream-id and payload.
Three stream types are made available:
1. Control
2. Gossip
3. Git
This change brings the following improvements:
* Removed need to queue fetch requests
* Removed need to queue gossip messages
* Removed need for `Fetch` and `FetchOk` messages
* Service doesn't need to know about inbound fetches
* Removed one round-trip for fetch negotiation
* Removed special `done` git packet
* Removed session logic and state around Git/Fetch protocols
* Removed code around upgrading/downgrading transport
* Worker in responder mode is able to process any number of fetches
* Connections support any number of concurrent fetches
We had to introduce a few extra things however to make it all work:
* A `VarInt` type for variable-length integers, since we want the frames
to be lightweight.
* A custom "tunnel" implementation, since we couldn't use the existing
one anymore.
Overall the change removes more complexity than it adds, while improving
the protocol along the way.
* Properly remove review help message from review
* Remove `--no-confirm` and confirmation step
The CLI should be mostly non-interactive for day-to-day commands,
keeping the interactivity for the TUI.
When a merge is applied to a patch, we check whether the threshold
of delegates has been reached, at which point we set the patch status
to `merged`.
This requires threading the identity document oid through the "apply"
process.
Revision IDs are globally unique. Users will be able to use the
Revision ID in place of its patch ID.
Make `rad merge` refuse to merge an older revision unless the `--force`
option is given.
Using LWWReg::from will always set the clock value to the default,
which can end up being used wrong.
Instead, introduce a constructor method `initial` to indicate that it
should be used on initial construction, while `new` should be used for
newer values of the register.

Support users with systemd integration by providing a systemd service
file. The file includes basic instructions for how to adapt to the
users context.
There are two scenarios it would be run in, as a system service, or as a
user service. The scenario as a user service is problematic.
`radicle-node` relies on ssh-agent or a clear text RAD_PASSPHRASE.
This fixes an issue that came up in tests where we would be reading
and writing to the database at the same time, and it would fail with
an error due to the lock being contended on.
Replaces pub accessors to struct fields with methods
Also creates some methods to compute necessary information

The One variant caused many paint points for fetching logic, where it
was not necessary. It was only constructed in one place, which could
be replaced by using the variant that holds a set of keys.
Remove the Namespaces::One variant and rename Namespaces::Many to
Namespaces::Trusted.

When a repository does not yet exist during a fetch, i.e. a clone,
then only delegates are being fetched.
Augment Namespaces::Many to hold the trusted and optional delegate peers
separately. Doing so allows the construction of the variant without
the repository existing, but tracking relationships existing.
This variant can then be used to build refspecs for both the trusted
peers and delegates when doing a cloning fetch.

Previously, if a peer created a project which was replicated and then
moved to another setup, ultimately deleting that project, then they
would not be able to fetch it again since their remote namespace would
be excluded from the fetch.
This test confirms that a peer can remove their project and clone it
again from a peer that has replicated the project. This is simulated
by directly removing the project directory in the test and fetching
the project from the other peer.

With the latest fetch updates, the test for fetching trusted remotes
can be enabled.
The caveat is that its expected behaviour is to fetch the delegate
upon a clone and fetch all trusted peers on a subsequent
fetch. Fetching all trusted peers is left as a follow-up task.

The previous fetching logic had some pitfalls regarding its logic:
* Fetched 'rad' references could end up not being verifiable and leaving
the storage in a corrupt state
* Forced pushes would be prohibited, since they would be rejected by
the client side due to the refspecs being used.
The new approach is to stage a fetch in 2 steps. The first step is to
fetch the relevant `rad/id` and `rad/sigrefs` for verification. For
all remotes that are verified, fetch all references listed in their
respective `rad/sigrefs`, using the `+` marker in the refspec,
allowing to update for any force pushes -- note that this becomes a
safe operation since the `sigrefs` are signed by the remote that
created them.
To prevent unverifiable 'rad' references from polluting storage, all
fetch negotiations are done in a staging repository set up in a
temporary directory. All successful fetches are then transferred,
using the 'file://' protocol, from the temporary directory into the
radicle storage.
