Though these are perhaps not the final error types, we name them the same
across COBs and have them work the same way.
All COB modules now have a `Error` enum.
In a future change, we may want the `FromHistory` trait to support
multiple error types, eg. one for `apply` and one for `validate`.
This adds a simple `validate` function to COBs that is run on load. It
allows COBs to check whether they are valid, once all operations are
loaded, and return an error if not.
This change updates to the latest radicle-git-ext, which required a
few changes within the radicle family of crates.
One set of changes is that the radicle-git-ext crate subsumes
git-commit, git-trailers, and git-ref-format -- so all those imports
go through radicle-git-ext.
The commit code requires that parent `Oid`s point to commits, which
made some tests fail. One of the reasons for these failures is that
the patch tests used fabricated `Oid`s and so the verification would
fail. This is fixed by allowing the test context code to create
`PatchRequest`s that create valid commits.
The other reason for failure was that the identity `Action` passed an
`Oid` that pointed to a blob. This is fixed by removing that code and
making a note of it in documentation.
The final major change was moving the Refspec type into git-ref-format
and removing the AsRefspecs trait. The trait was not required and
could its usage could be replaced by simpler code.

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.
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.
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.

By introducing a small limitation: only allowing entries in the change
graph to be addressable, instead of individual operations; we
drastically simplify the CRDT implementation.
There are four advantages:
1. Op ids are just regular SHA-1s
2. There's no need for relative IDs, ops never refer to other ops within the
same commit
3. There's no need for a nonce, since commits can't collide, and neither can op IDs
4. `OpId` can just be an alias of `EntryId`
The disadvantage of course, is that we have to be mindful of how we
create op transactions, since each transaction creates an addressable
unit. For example, we must not include multiple patch revisions in the
same transaction.
It's fairly easy for a user to (by mistake or intentionally) create two
operations with the same OpId. This patch makes it much less likely,
and ensures that if the OpId is equal, it's because the operations
are identical.
Instead of showing just public keys we need to show the fully qualified
spec for a NID which is prefixed by `did🔑` While we want to maintain
`Author` and `ActorId` for internal use.

In order to make identity changes where the threshold is higher than
1, it is necessary to gather signatures of delegates to surpass that
threshold.
To achieve this the Proposal cob is introduced for proposing changes
and gathering the signatures over those changes.
Once a quorum is reached the Proposal can be published, committing the
new identity document to storage.
