Most of the test flakiness was caused by the git-daemon not being able
to bind to a port. It seems like using an RNG was not a good enough
solution.
After this change, tests seem to be passing without issue.
Our build was faking the inclusion of SQLite and dynamically
linking it in the 'radicle' crate and other components.
This patch solves the following error and requires reinstallation
of the `radicle-cli`, `radicle-node`, and, if used, the `radicle-httpd`
```
✗ Sync failed: internal error: malformed database schema (node-policies) - near "strict": syntax error (code 11): malformed database schema (node-policies) - near "strict": syntax error (code 11)

Previously, we only sent the announcement when there were external
addresses. But it contains other information like the node alias,
therefore we always send it.
Since the proof-of-work can be expensive to compute everytime, we add
the ability to load the local node announcement from the file system.
We also change the proof-of-work parameters so that they are relaxed
when running in debug mode, instead of when running tests.
Finally, we remove the boolean validation of the PoW. Instead, we store
the work per-node, in the database, to be used in the future in case of
DoS attacks or network congestion.
Previously, only one connection to the node control socket could be
handled at a time. This usually worked fine, but if one connection hangs
for whatever reason, no other process can access the node.
It turns out it's possible to create a deadlock when using
`child.wait()` with `Stdio::piped()`, if we don't read the output while
the child process is running. This is because the pipe has an internal
kernel buffer that will eventually fill up, causing the child process to
block on writing to stdout and never exit.
To remedy this situation, we read the stdout in a thread while the child
process is running.
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.

When attempting to connect to a peer, and when succeeding, write the timestamp
to the database.
This will allow us to better select addresses and not retry peers to
soon.
On macOS, shutting down a socket returns an error if the socket is
already closed. We don't consider that a problem, as it just returns
`Ok(())` on Linux.
We fix the failing fetch tests by:
1. Not verifying our own refs, unless we're cloning, since we're
otherwise not fetching our own refs.
2. Always force-fetching `sigrefs` from remotes into the staging copy.
3. Making sure that sigref updates are fast-forward before transfering
the remote into the production copy.
Ensure that the production repository is validated after fetching and
performing deletions. This is to highlight any inconsistencies that
may show up between fetching and deleting references.

Given the scenario of 3 peers, A, B, and C each having a project R. If
peer A has B's fork, but C does not, then when peer A attempts to
fetch from C the fetch will be rejected since Git will fail when a
refspec that is asked for does not exist on the remote side.
To avoid this, the fetch logic is changed so that the client first calls
ls-remote to the remote side, which results in the references that the
remote has which the client is interested in. The follow-up fetch then
uses these refs as the refspecs -- which should succeed unless there
was a race for a deletion on the remote side.
The rest of the verification logic stays the same, so the storage
should still be in a working state before transferring from the staged
repository to the production repository.

Ensure that non-existent tracking relationships do not affect
fetching.
This is tested by first performing a clone, by `bob` from `alice`,
after `bob` tracks a remote that does not exist. `alice` creates an
issue which is then fetched by `bob` -- to ensure the fetching
scenario is also tested.

We were allowing remotes to be constructed via a function that didn't
check its inputs.
This is now fixed by moving the public key into the `SignedRefs` struct.
It's currently possible for a channel to be blocked forever while
waiting for data, if the remote peer keeps the connection alive.
This can occupy a worker indefinitely.
With these timeouts, we ensure that workers exit if there is no
activity after a certain amount of time.
This command announces refs to peers and waits for them to be
in sync.
Adds a subscribe method to `Handle` so that we can get the events
from the seed to allow us to confirm that the configured seeds fetched
from us.
By having the keep-alive delta be the same as the ping timeout,
we essentially disconnected peers right after we sent them our
first ping.
This fixes that issue by setting the ping timeout to double the
keep-alive delta.
Instead of returning the namespaces that we fetched with,
we return the remotes that were actually fetched from.
This can differ if some trusted peers were not available
on the remote node.
Previously, if that was the case, it would cause errors
since the remotes were looked up and that lookup failed.
