99bca8ad3f Suppress uid == 0 check in unit tests
Our `make check` runs an unprivileged rpm-ostreed if run as non-root; this is a
feature. We didn't notice in the CI tests since those run as "docker-uid0". It
does break my local workflow though.

b3e16a3313 bwrap: Turn on all namespaces
The fact we weren't doing this is an oversight.  We should *really*
be using the PID namespace at a minimum, but I decided to just turn
them all on.

The one that seems most likely to potentially introduce a regression is turning
on the netns (i.e. disabling networking). But I can't really think of what we'd
be running in a script today that would break in practice.

f8edd59d5f daemon: Introduce an origin structure
In prep for adding "regenerates initramfs" to "is locally assembled",
we need more abstraction.  I previously introduced a helper function, but
I'd still need to touch every call site when changing that.

Rather than having each caller re-parse the origin, let's parse it once into a
structure, and then have error-free accessors for it (that also don't malloc).
This way when adding a new flag, I don't need to touch every call site.

Notes:

 - Some places in the code (like the deployments -> variant bits) tried to
   handle deployments without an origin gracefully.  That's no
   longer true.  I'm not sure how much we care - do we?
 - There are a few places where I changed `packagelist.len() > 0` to
   `is_locally_assembled()`.  I think this is right, but we'll need
   to be sure the "no packages to overlay, just initramfs" case
   works when that lands.

e1cdfa1712 libpriv: Introduce an rpmostree-kernel.[ch] for dracut
Since the dracut run is now separated from the rest of postprocess, we change it
to use the bwrap API diretly, and this lets use the new _IMMUTABLE bwrap type.
This will make it easier to reuse for client-side initramfs regeneration.

Splitting this off makes it also easier to simplify the remaining mutable
usage in postprocess.c.

f0ec738376 libpriv: Enhance internal bwrap API
Make it a real struct with methods.  This noticeably increases
the ergonomics and design of the API.

The main goal here is to introduce the enum which defines whether or not the
rootfs is mutable or not. We move the "rofiles" mode from the RPM script code
down into the bwrap layer, which will make it easier to reuse for treecompose.

50ab2983ab postprocess: Use O_TMPFILE for dracut, merge reproducible bits
I was planning to do some further changes here, and I really don't like the
manual fork/exec stuff on in the --reproducible checks. Our subprocess code
should basically be all bwrap.  Synchronous code execution while not reading from the
pipe is a recipe for deadlocks.

What simplifies things a lot is to write to an `O_TMPFILE` fd (or a tempfile on
legacy kernels), and slightly extend our bwrap-executing code to support a child
setup function, so we can set the tmpfile fd to be stdout.

Now that we have a shell script wrapper we inject, it's trivial to reimplement
the "detect reproducibility" in shell script there, rather than C.

This doesn't matter much for treecompose today, but it will matter more when
we're supporting client side initramfs regeneration, since now the dracut
container can be fully immutable.

e32bbf16d1 passwd_prepare_rpm_layering: account for local entries
On Fedora 25, systemd adds a sysuser config file for multiple users. It
also explicitly creates those same users in its %pre, except for one:
systemd-coredump. This means that the tree's /usr/lib/passwd doesn't
contain systemd-coredump. Of course, on first boot, it gets created and
added to /etc/passwd.

During package layering, we map /usr/lib/passwd to the container's
/etc/passwd. If the %pre calls useradd/groupadd without passing an
explicit uid/gid, it's possible that the allocated id is already in use
by an entry in the deployment's /etc/{passwd,group} (such as
systemd-coredump, but the same holds for any manually-added entry).

We resolve this by taking the switcheroo a step further: we map
/usr/lib/passwd to /usr/etc/passwd, and then also map /etc/passwd to
/usr/lib/passwd. That way, useradd in %pre will account for already
allocated local uids and react accordingly.

b68209b6d4 daemon: start with one commit only when resolving versions
During a deploy operation, we would fetch commit objects from the remote
to resolve the version string. If gpg-verify was turned on, we would
fail to pull them if some of the commits were not signed. This is
because we pulled them in batches. We partially address this by only
fetching the HEAD commit on the first pass. This allows `upgrade`
operations to work just as well as `deploy` operations.

Though there is still an issue if we have to traverse farther back than
when signed commits become unsigned (unless they happen to fall on a
batch boundary). We leave that unsolved for now, since that would likely
require a more complex solution and it's not clear whether it's a real
world issue (signers can just retroactively sign commits).

Copy the gpghome from ostree so that we can test GPG-related cases in
our suite.

e10c97007f rebase: add support for rebasing to a specific rev
Expand the available options in the Rebase() D-Bus method to also have a
"revision" key. Its value has the same semantics as the "revision" key
in the Deploy() method (e.g. the "revision=" and "version=" prefixes are
also supported). Also expand the rebase CLI to allow for specifying the
revision as an additional argument.

This allows users to rebase to a specific version or checksum, rather
than only to the latest. Conceptually, this is the equivalent of doing a
rebase followed by a deploy. I.e. we specify an override-commit in the
origin and expect the same behaviours that apply after a deploy to also
apply here.

c5fa202378 sync.sh: tweak for container workflow

However, when using git worktrees (which is useful in this scenario to
avoid having to overwrite your local builds) and a CentOS build
container, the git inside is too old to understand worktrees, so let's
avoid invoking git in any of the test harness scripts.

5bf7a040a5 libvm.sh: strengthen reboot
Unsurprisingly, rebooting machines that are running in OpenStack is
not as reliable or as fast as a local VM, which is what vmcheck was
originally written for and tested against.

Replace the:

  sleep 2 # give time for port to go down

which is rife with raciness, with a stronger boot_id-based check to
ensure we're in a new boot. Run "sync" before rebooting which sometimes
helps (though I didn't fully investigate why or whether it always helps,
there's probably something more subtle going on underneath). Increase
the timeout to 120s.
