Implement caching for the `Issue` and `Patch` COB. This is achieved by
having the `Transaction::initial` and `Transaction::commit` methods
take a cache which can update the newly created/updated object. The
`Store::remove` method also takes the cache for removing the object
from the cache, as well as the repository.
This meant that the `*Mut` types for the respective COBs are required
to carry a cache alongside the repository store. Identities will not
be cached, and so this is always set to `NoCache` -- which performs no
caching, and always succeeds.
To perform cache reading for issues and patches, the `cache::Issues`
and `cache::Patches` traits are introduced. They capture the minimal
amount of methods that are needed for the `rad issue` and `rad patch`
CLI commands.
The implementor for each of these traits is there respective `Cache`
types, which combines their backing repository store and the SQLite
database. They both provide convenience methods:
- `create` (and `draft` for patches)
- `get_mut`
- `remove`
which can be used instead of their repository store counterparts.
All uses of the repository stores (where needed) are replaced with
`Cache` types.

Shell out to `git`, avoiding using `git2`. This is to avoid an
issue where somewhere within the fetch there is an attempt to lookup a
`rad/sigrefs` object, which says that the object is missing. It is
suspected that this is due to the object being localised in the same
packfile as other objects we are fetching. Since the `rad/sigrefs`
object is never needed nor used in the working copy, this will always
result in the object missing. This seems to only be an issue with
`libgit2`/`git2` and not `git` itself.

It's actually not such a great idea to sync on git-fetch and
git-ls-remote, as syncing is supposed to happen in the background
already, and if you want to force a sync, you can just call `rad sync`.
Previously, it would be annoying that when you called `rad sync` and
then `git fetch`, it would still attempt another sync, for example.
Moving forwards, it might make sense to call `git-fetch` on `rad sync`
(so the other way around), because `git-fetch` is free (it doesn't talk
to peers), and you almost always want your working copy up to date with
your storage.
This makes the divergence check on push slightly more lenient, by
allowing rolling back to a previous commit in the canonical branch
history.
Without this, it can become impossible to roll-back commits in certain
situations.
When specifying a `patch.base` to point to for stacking patches, it's
useful to accept any kind of revspec, e.g. `HEAD^`.
Change the argument parsing to use the `Rev` type instead, and change
the `rad-patch-ahead-behind` to use `HEAD^` to test the example usage.

Changes the behavior of `git fetch` by running a radicle network-level
fetch (ie. `rad sync --fetch`) before fetching refs from storage. This
avoids having to run `rad sync` before `git fetch`; and tries to make
sure that refs are always fresh.
Allows for setting a patch message during a push. Eg.:
$ git push -o patch.message="My Title" -o patch.message="My description" \
rad HEAD:refs/patches
Works the same way as the `-m` flag of `git commit`.
This adds the ability to the git-remote-helper to open and update
patches via a `git push` to the magic ref `refs/patches` and
`refs/heads/patches/<patch-id>`.
The main change is that we had to move away from offering the `connect`
capability in the remote helper, to offering `push` and `fetch`
individually.
To get a feel for how this works, see the `rad-patch-via-push.md`
example.
Instead of `Node::announce_refs`, we call `rad sync` to have the
terminal block while waiting for nodes to fetch the changes.
We also change the use of `git push` in the patch command to not
trigger syncing in that case.
There is no mechanism for fetching the canonical `refs/heads/master`
from a project's repository into a local working copy.
Allow setting up a remote in the working copy, e.g.
[remote "canon"]
url = rad://z3gqcJUoA1n9HaHKufZs5FCSGazv5
fetch = +refs/heads/master:refs/remotes/canon/master
Such that it can fetch the `master` branch, but disallows push to the
canonical reference namespace.
This is achieved by allowing the namespace in `radicle::Url` to
be `None` when the radicle-remote-helper is called. It disallows the
namespace to be None during a `git-receive-pack` -- also keeping the
check for the namespace being equal to the local operator's key.
When the namespace is `None` then `GIT_NAMESPACE` is set to the empty
string.

By allowing the node to run using a `MockSigner`, we speed up tests
significantly, since PBKDF2 doesn't need to run.

In interactive (user) contexts, use `try_sign` instead of `sign`.
We also revisit the `Profile` by adding a `signer` method that can
fail, eg. if we couldn't connect to ssh-agent.
Finally, we replace `UnsafeSigner` with `MemorySigner`, which makes
use of `ssh::Keystore`.

The crypto types are useful to use in other components that are
separate from the radicle crate, e.g. the incoming radicle-cobs
crate.
Separate out the types into a radicle-crypto crate. This crate defines
the usual PublicKey, SecretKey, and Signature types. It also provides
the ssh functionality, under the `ssh` feature. It is also necessary
to provide the `From` impl for `Component` here, which again is
guarded by the `git-ref-format` feature.
The `Arbitrary` implementation are moved. The arbitrary decision of
redefining `ByteArray` in both radicle-crypto and radicle was made.

To distinguish between working-copy-to-storage (local) and
storage-to-storage (remote) replication, we create two new
URL types: a `remote::Url` (`heartwood://`) and a `local::Url`
(`rad://`).
These schemes are to be used for the remote and local transports,
respectively.
The difference between the two schemes is that remote replication
requires a node id.

We set the `HEAD` and eg. `refs/heads/master` refs when updating
repositories, which allows users to easily clone with git.
For now, `HEAD` is chosen based on a unanimity quorum of delegates.
This can be made more sophisticated in the future.
We've also had to ignore some refs during verification, since these
have cropped in for eg. due to the staging copy clone and the
changes included here.
