I'm trying to get ostree tests to pass in OpenShift as part of our CI

create-usb: Update summary in destination repo
Currently the create-usb command only generates a summary file in the
destination repo if one doesn't already exist, which means if one does
exist it becomes out of date after the new refs are pulled. This commit
makes ostree regenerate the summary regardless of whether it exists, so
that consumers such as ostree_repo_find_remotes_async() (and at a higher
level, GNOME Software) get an accurate picture of the refs available on
the mount. This commit also updates one of the unit tests to check that
the summary is accurate after a second pull into the same repo.
Since any user of the create-usb command is using collection IDs they
are new enough to be using the unsigned summary support. While it would
technically be possible to use summary signatures on a repo and use the
create-usb command on it (a scenario broken by this commit), the
create-usb command is designed for P2P distribution of refs, which
requires use of unsigned summary support. So this is a legitimate

lib/sysroot: Move staged into deployment list, rework handling
Followup to: https://github.com/ostreedev/ostree/pull/1503
After starting some more work on on this in rpm-ostree, it is
actually simpler if the staged deployment just shows up in the list.
It's effectively opt-in today; down the line we may make it the default,
but I worry about breaking things that e.g. assume they can mutate
the deployment before rebooting and have `/etc` already merged.
There's not that many things in libostree that iterate over the deployment
list. The biggest change here is around the
`ostree_sysroot_write_deployments_with_options` API. I initially
tried hard to support a use case like "push a rollback" while retaining
the staged deployment, but everything gets very messy because that
function truly is operating on the bootloader list.
For now what I settled on is to just discard the staged deployment;
down the line we can enhance things.
Where we then have some new gymnastics is around implementing
the finalization; we need to go to some effort to pull the staged
deployment out of the list and mark it as unstaged, and then pass
it down to `write_deployments()`.
This is a version of ostree_repo_traverse_commit_union that also
remembers where the objects came from, by recording the parent
relationships in a hashtable. This can be used to later find which
commits each object was from, which we want to use in fsck.
Differently than the original implementation, now we don't attempt any
test for reflinks support on the parent repository, since the test
requires write access to the repository.
Additionally, also check that the two repositories are on the same
device before attempting any reflink.

lib/repo: Add timestamps to OstreeRepoFinderResult
Currently OstreeRepoFinderResult, a data structure used by pull code
that supports P2P operations, has a hash table mapping refs to checksums
but doesn't include timestamp information. This means that clients have
no way of knowing just from the OstreeRepoFinderResult information if a
commit being offered by a peer remote is an update or downgrade until
they start pulling it. The client could check the summary or the commit
metadata for the timestamps, but this requires adding the temporary
remotes to the repo config, and ostree is already checking timestamps
before returning the results, so I think it makes more sense for them to
be returned rather than leaving it to the client. This limitation is
especially important for offline computers, because for online computers
the latest commit available from any remote is the latest commit,
period.
This commit adds a "ref_to_timestamp" hash table to
OstreeRepoFinderResult that is symmetric to "ref_to_checksum" in that it
shares the same keys. This is an API break, but it's part of the
experimental API, and none of the current users of that (flatpak,
eos-updater, and gnome-software) are affected. See the documentation for
more details on "ref_to_timestamp". One thing to note is the data
structure currently gets initialized in find_remotes_cb(), so only users
of ostree_repo_find_remotes_async() will get them, not users of, say,
ostree_repo_finder_resolve_all_async(). This is because the individual
OstreeRepoFinder implementations don't currently access the timestamps
(but I think this could be changed in the future if there's a need).
This commit will allow P2P support to be added to

Related to this, we were erroring out if we had the karg but

using `ostree admin --sysroot` from an ostree-booted system! It's
actually a bit surprising no one has reported this so far; I guess
in the end people are either using non-ostree systems or running
from containers.
Let's add a member variable `root_is_sysroot` that we can use
to determine if we're looking at `/`. Then, our more precise
"should find a booted deployment" state is when both `ostree_booted`
and `root_is_sysroot` are TRUE.
Next, rather than walking all of the deployments after parsing,
we can inline the `fstatat()` while parsing. The mild ugly
