940fc1364a compose: Check that add-files are compatible after parsing
While serde gives us type checking, it of course doesn't understand
semantics beyond that. One example is checking the compatibility of
`add-files` entries with the OSTree model. This is something we can do
upfront early on to avoid surprises for users.

Also tweak the docs to reflect this new check.

245d238563 Use autocleanup for task output
I was playing with https://crates.io/crates/indicatif
and this is prep for using it.

By using autocleanups here we ensure that the output state
ends even if we encounter an error.  We previously had a few
explicit `failed` prints in cases where failure was more common
such as dependency resolution, but that was far from consistent.

Now we will always ensure a newline is printed even if an error
occurs, and we won't have to worry about missing calls to
`_task_done()` in the success case.

The downside of this is that we lose the `done` bit in the success
path...I thought about maybe taking a pointer to the error and
printing `done` or `failed` depending on whether it's non-`NULL`
but eh...the `done` is implied by us going on to the next line.
Also that issue will be fixed with the indicatif work.

fca01e70b5 Lower initial SELinux policy load from compose to core
Add a `selinux` verb to treespec, and bind it from treefile.  If
set, use it in the core to load an initial policy before import,
if we didn't already set a policy.

In practice right now this is only used from the compose path
since the SysrootUpgrader uses the policy from the merge deployment.

Unset the policy if rojig mode is enabled.

Now, non-SELinux use cases are required to set `selinux: false`
in the treespec. For `ex container` I just set it in our example
specs.  Probably that should forcibly disable it in the
treespec but eh, it's experimental.

The other case I can think of is client-side layering; before
we would create a policy using the target root, but it
wasn't a *hard* requirement, i.e. we didn't error out if
`policy_get_name() == NULL`.  Let's preserve that semantic by
hooking off of whether `_new_system()` was used.

Prep for sharing code with `compose rojig`.

67a831b043 rust/journal: Adapt for el7 platforms
Supporting ancient systemd is painful, though given that it may end up

Basically, the big changes here are:
- avoid using `_SYSTEMD_UNIT` since it might be missing in some entries
- also grep for the el7 version of the systemd msg when a service fails
- use `_TRANSPORT=stdout` for the error msg in case of ordering issues

b3f6f25637 core,scripts: When no cachedir+unified-core, disable rofiles-fuse
This is prep for running inside (unprivileged) Kube containers
as they exist today: https://github.com/projectatomic/rpm-ostree/issues/1329

Sadly FUSE today uses a suid binary that ends up wanting CAP_SYS_ADMIN.
I think there's some work on FUSE-in-containers but I'm not sure of
the current status.

What rofiles-fuse here is doing here is protecting is the hardlinked
repo imports.  But if `--cachedir` isn't specified, that repository
gets thrown away anyways.  So there's no real value to using FUSE
here.

Also since nothing is cached, disable the devino cache.

We also make use of --force-copy-zerosized that just landed
in libostree: https://github.com/ostreedev/ostree/pull/1752

Down the line ideally we gain the capability to detect if either
unprivileged overlayfs/FUSE are available.  Then if `--cachedir`
is specified we can make things work.

8ba5bda821 core: Apply s{u,g}id consistently on checkout
This is basically overriding what happens with `bare-user` mode
OSTree repositories.  I put a lot of thought into avoiding creating
suid files with that mode.

But today this creates a situation where if we don't have a devino
cache, the file will lose its suid bits.

In the end, since we're using the "inaccessible directory" pattern
anyways for rpm-ostree on the host, we don't need to really worry
about transient suid binaries.  And similarly when we're run inside
an existing container, that's also fine.

aa485b7625 Fix cache_age handling for compose and client-side
PR: https://github.com/projectatomic/rpm-ostree/pull/1562
AKA commit: a7bbf5bc14
introduced two regressions.  First one for `compose tree`.  The intention is
the default there is to *always* immediately check for updated
rpm-md - a bit like `yum clean expire-cache`.  However due
to bugs in the stack we end up downloading it again anyways, but
that's not the topic here.

When we made that change we basically stopped using `DnfContext`'s
`cache_age`, which is what `compose tree` was setting.

Introduce a new explicit API to do what we want for `compose tree`.

Secondly, we were mistakenly always caching on the client
side.

This also fixes an issue that `--cache-only` didn't work, it basically
just made `compose tree` use the default `metadata_expire`.  Now we
really don't expire it.
