This was useful to have in CI, e.g. when targeting a specific NixOS
system. The actual result symlink which is printed is not useful.
Alternative solution would be to change the wrapping of this so that
we conditionally create the symlink for extra steps, but I think it's
not worth the complexity of evaluating the step twice.

This changes the logic for build pipeline generation to inspect
an (optional) parentTargetMap attribute which contains the derivation
map of a target commit.
Targets that existed in a parent commit with the same drv hash will be
skipped, as they are not considered to have changed.
This does not yet wire up any logic for retrieving the target map from
storage, meaning that at this commit all targets are always built.
The intention is that we will have logic to fetch the target
map (initially from Buildkite artefact storage), which we then pass to
the depot via externalArgs when actually generating the pipeline.

The file is always uploaded to Buildkite as an artifact. This allows
for retrieving it based on the commit ID in a Buildkite GraphQL query.
By default, Buildkite stores artefacts for 6 months. Storage location
can be overridden (with custom retention) through some environment
variables, but for now at TVL the Buildkite-managed storage is fine.
See also: https://buildkite.com/docs/pipelines/artifacts
In the subsequent filtering implementation, when diffing commits
across a time-range that exceeds artefact retention time, we should
simply default to building everything.

Note that this has a small functional change: In error messages of the

than the Perforce-style `//` notation common in TVL.
For example, an error at `//web/tvl/logo` will produce `web.tvl.logo`
in the error message (which corresponds to the readTree attribute
itself).
This makes more sense for non-TVL consumers of readTree, as the
Perforce-style notation is custom to us specifically.

In order to make readTree import symlinked directories I've been looking
into how to detect if a symlink points to a directory (since this would
allow us to use symlinks for //nix/sparseTree). I've found a hack for
this:
symlinkPointsToDir = path: isSymlink path &&
builtins.pathExists (toString path + "/.")
Unfortunately it doesn't seem to be possible to distinguish whether the
symlink target does not exist or is a regular file.
Since it's possible, I thought might as well add this to
`pathType`. To make returning the extra information workable, I've
elected to use the attribute set layout used by `//nix/tag`. This
doesn't require us to depend anything (as opposed to yants), but gives
us pattern matching (via `nix.tag.match`) and also quite idiomatic
checking of pathTypes:
pathType ./foo ? file
(pathType ./foo).symlink or null == "symlink-directory"
Nonexistent paths are encoded like this:
pathType ./foo ? missing
Of course we can't use this in readTree (since it must be zero
dependency), but we can easily inline this hack at some point.
