50b255a8a9 Move varsubst code into Rust, use it in treefile parsing
External tools often want to parse the ref; for example coreos-assembler
currently does so.  Let's ensure `${basearch}` is expanded with
`--print-only` so they can parse that JSON to get the expanded version
reliably.

Implementation note: this is the first Rust code which exposes a
"GLib-like" C API, notably with GHashTable, so we're making more use
of the glib-rs bindings.

c3be38af72 postprocess: Minor glnx_console interaction fixes
Make sure we always pass an integer and not a float to
`glnx_console_progress_text_percent`. And also make sure we clamp the
value we pass to 100. Not sure how I hit this, somehow the byte counting
we do upfront before committing is *less* than the addition of all the
`g_file_info_get_size()`s?

5c4e88da9c core: use DEVINO_CANONICAL regardless of repo type
If the policy didn't change, then it's safe to use the devino cache
regardless of the repo type. This dates from #1123; I think the
rationale there was so that it only affects the pkglayering path, where
the system repo is bare. But really, it should be fine to generalize
this since we don't have any xattr callbacks.

6d39cfa78f compose: Don't require SELinux policy in legacy path
In #1630, we lowered SELinux policy loading into the core. However, this
also enabled SELinux policy loading from the host system even in the
legacy (non-unified) compose path. This meant that compose systems now
needed to have the policy installed even though we didn't need it at
all. This caused regressions in pungi:

https://pagure.io/dusty/failed-composes/issue/956

Just make the binding of the "selinux" member conditional on whether or
not we're in unified mode (which is really when we even care about
having it loaded from the start for pkgcache purposes).

79d4e52d99 app: Wrap Version in --version in quotes
Wrap the `Version` key in the YAML-compatible output of
`rpm-ostree --version` with quotes so that it's parsed as a string. The
issues with the previous approach in a nutshell:

```
In [5]: yaml.load("asdf: 2018.10")
Out[5]: {'asdf': 2018.1}
```

It's treating the version number as a floating-point. Now, this is
technically a backwards incompatible change, but given that the previous
approach is inherently broken for our needs, I don't see a way around
breaking it now.

88ffdc0ae2 Add compose rojig command
This currently requires a `--i-know-this-is-experimental` flag;
I know it'd be a bit more consistent to have it under `ex`, but
what feels weird about that is *most* of the `ex` commands people
use are client side.  This is where we want it to ultimately end
up.

We've landed a lot of prep patches, but I know there's still
a notable amount of code duplication with `compose tree`.  What's
left is about ~700 lines but it's mostly not hard/complex code
anymore.

In the future, I'd like to extract more of the compose code
to a `rust/src/compose.rs` or so, but I think this is sustainable
fow now.

My high level goal is to get this into coreos-assembler and stand
up a Silverblue build that uses it.

99776be162 core: Disable librpm SELinux plugin when writing rpmdb
OSTree was designed from the very beginning of its existence
to support SELinux well instead of being something wedged on.
rpm-ostree builds on that foundation.  We don't want to have anything
to do with librpm's SELinux code.  And with unified core,
we usually don't, but that `rpm-plugin-selinux` code does get loaded.

Disable it here.  The main reason I'm submitting this patch
is to help an effort in coreos-assembler to use a "supermin" virtual
machine: https://github.com/coreos/coreos-assembler/pull/124

f3b8ef043e libpriv: Sanity check that paths are OSTree compatible
I originally was going to add the check here and error out to the user,
but `add-files` is handled all the way near the end of the compose,

still useful at postprocess time as well as a sanity 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.
