First step towards giving depot modules the ability to declare their
own backup directories by moving all restic configuration into a new
module and adding a NixOS option for inclusion/exclusion paths for
backups.
This still keeps all backup paths within the whitby config.

Previously we served the dumb git HTTP protocol from code.tvl.fyi via
cgit. This CL disables this feature and instead runs josh in the same
location (by redirecting appropriately), but while also enabling
partial cloning of all subtrees of the depot.
For example, after this CL the following would result in an
independent clone of //nix/readTree:
git clone https://code.tvl.fyi/depot.git:/nix/readTree.git
Note that there are no josh workspaces configured at all for now,
these references are only for static depot subpaths.
Please refer to the documentation for josh for more information on
available kinds of josh filters.
Josh state is kept in a systemd state directory in /var/lib/josh and
backed up to Restic. Backing this up is necessary, as josh uses
stateful information to do things like tracking merges and rewriting
history per subtree appropriately to avoid cloned repositories ending
up in peculiar states.

Add the beginnings of an auto-deploy script for whitby, intended to
be (eventually) suitable for running automatically in a systemd timer.
The current iteration of the script doesn't actually do any deploying,
but instead takes as an argument a revision, creates a new git worktree
in /tmp with that revision checked out, runs a nix-diff of whitby's
system derivation in the running system and at that closure, puts an
html-rendered version of that diff in the public directory used by
deploy.tvl.fyi, and finally sends a message to IRC via irccat with a
link to that HTML page.

We changed the configured pipeline in Buildkite to upload
`static-pipeline.yaml` instead of containing the steps of that
pipeline itself.
This makes it easier to test changes to builds and such, but adds
another build step with scheduling overhead etc.
However - we can work around this by killing one of the existing build
steps. There's no reason the failure status zeroing (required for
status reporting) shouldn't be part of the pipeline setup, so I've
moved it there instead and nuked that step.
This should mean that the pipeline is configurable from within the
repo, but without slowing anything down.

Skip build steps if they have already been built, reducing pipelines
to the things that actually changed between builds. On canon all
targets are always built (we require this for anchoring).
Note that this is not perfect, garbage collection and competing
pipelines may affect each other.
Also note that we have some impure targets that change on every
commit.

We currently evaluate every target twice -- once when the depot pipeline
is built and once when actually running the build step in question. Nix
evaluation is quite slow especially given heavy use of import from
derivation in depot, so avoiding the second evaluation is desireable.
Evaluating a derivation yields a `drv` file in the nix store which can
be passed to `nix-store --realise` in order to build it eliminating the
need to wait for evaluation. We can obtain the path to the `drv` file
while building the pipeline via `target.drvPath` and remember it for the
build later.
However we need to work around a flaw (or oversight) in Nix's dependency
tracking via string context: This is based on derivations, not output
path (because this is what evaluation deals with, likely). This is no
problem per se, but an issue is that Nix can't express a dependency on
a `drv` file without any of its output paths. This means for us that we
either have to build all output paths at evaluation time (which we don't
want, obviously) or to deal with the fact that the `drv` file we need
may be garbage collected at any moment after discarding the string
context -- then nix is unable to track the reference from the pipeline
to the `drv` file in the store.
So to prevent a race condition between the pipeline and the garbage
collector we fall back to the normal nix-build invocation as we did
before.

This is a bit of an under-documented feature, but if the "tag" field for
a gerrit review starts with the string
"autogenerated:<something>~<something-else>", only the last comment per
instance of <something> will be shown by default on the CL page (with
the rest viewable by toggling the "Show all entries" switch). The idea
behind the "<something-else>" tag is to be used for the "type" of
comment within a particular system - gerrit's documentation gives the
example of one tag for "the build is running" and another for "the build
has finished, here's the result".
