0e5c1cde96 compose: Move "serialized treefile" into Rust ownership
Now that we have `CUtf8`, let's just store the serialized JSON
as a string, owned by the Rust side.  This way we can drop the
`serialized_treefile` buffer we were passing around and simplify
various bits of code.  Most notably, we only serialize the JSON
once (via Serde) rather than also doing it again in the C side.

1d031fe51e core: Maintain /usr/etc as /etc when running scripts
In preparation for running in default Docker permissions where
we can `chroot()` and `makedev()` but not e.g. create bind mounts,
move `/usr/etc` to `/etc` when running scripts.

The script processing is also entangled with our passwd/group
file handling, so change those functions called from the core too.

It's tempting to basically maintain `/usr/etc` as `/etc` all
the way from immediately after checkout to just before commit.

We can't change how we do imports now; perhaps importing
RPMs into ostree as `usr/etc` was just a mistake in retrospect,
but oh well.

a86ad96669 compose: Support not specifying a ref
Split out of supporting "pure rojig" work.  We also want
to support this for doing "oscontainers" as is planned for
Red Hat CoreOS.  The user experience in both cases is oriented
around versioning of the external wrapper, not the inner ref/commit.

Note for users/builders who want to make use of this feature:
You probably want to mirror the changes in our test suite here to
use the compose JSON and parse the resulting `ostree-commit` out of that.

e3be475566 compose+rust: Parse includes via Rust too
This follows up to https://github.com/projectatomic/rpm-ostree/pull/1576
AKA commit 2e567840ca - we now process
treefile inheritance in Rust code.  Previously for elements which
reference external files (`postprocess-script` and `add-files`)
we'd hardcoded things to only look in the first context dir.

Now we open file descriptors in the Rust side for these "externals"
as we're parsing, and load them C side.  Hence we'll correctly handle
a `postprocess-script` from an included config.

Other advantages are that the include handling was ugly un-typesafe C code
with no unit tests, now it's memory safe Rust with unit tests.

The downside here is I ended up spelling out the list of fields
again - there's probably a way to unify this via macros but
for now I think this is OK.

426e16ee8b bwrap: Also drop constructor direct bwrap arguments
Following on to the previous change which added an explicit bind
mount API and also removed the API to append bwrap arguments, let's
also change the constructor to disallow the latter.

There was just one non-bind-mount argument being used
for "ro /var + tmpfs /var/tmp" - change that to an explicit new
API.

f50f9e8d7e Split cbindgen to separate build, support external version

locks serde to way old versions, and I want to use newer versions.

Since Fedora will now again ship a `cbindgen` package, let's

the cost of building it.

For distros that don't ship it (e.g. CentOS) for CI purposes
we build it.  For downstream builds that are offline, rather
than vendor the cbindgen sources like we do with our main Rust,
let's just vendor the `rpmostree-rust.h` file as was suggested

c6de759cc0 compose: Drop combined ostree+rojig compose tree
Currently `compose tree` supports writing to both an OSTree
repository and optionally simultaneously generating a rojig
RPM or rojig set.

We are instead going to split off a separate `compose rojig` verb,
since we want to support a "pure rojig" mode, and having all
3 options would make this code far too complex.

For now anyone who wants *both* formats can use `compose tree` then
follow up with `ex commit2rojig`.

This is also inline with the new coreos-assembler push, where
we'll treat `rpm-ostree compose` as more of a "low level" API,

So we have two choices: allocate, or internally use a `NUL`-terminated
type.  Let's just use `Box<CStr>` internally.  Note I chose that
over `CString` as the latter is theoretically mutable, and when
passing data back over to C we don't have ownership/mutability

We can further simplify the logic on the client side here by relying on
the fact that there is only a base layer iif we're layered, so we don't
need two output variables.

I find it also makes things much easier to grok in some places, e.g. in
`rpmostreed-deployment-utils.c`, we now have:

    const char *current_base_checksum = current_base_checksum_owned ?: current_checksum;

which better crystallizes what we want to get at.

897dd2839a postprocess: Don't copy base rpmdb when layering
We only want to copy our own rpmdb to the base rpmdb location in the
server-side paths. OTOH, when creating layered commits client-side, we
want to make sure that we *don't* touch the base rpmdb location.
Accordingly, move the logic that does the hardlinking into
`postprocess_final`.

This can cause issues if we want to make use of the base rpmdb (as in a
forthcoming patch) of commits that were not created by a recent enough
rpm-ostree which inject the base rpmdb. When layering on such base
commits, we would unwittingly copy the new rpmdb (with the layered
packages) into the base rpmdb location. This then of course throws off
any logic that assumes the rpmdb at that location is from the base
layer.

There's a slight compatibility issue here: there are still older layered
commits out there where we did this and which might throw off new logic
that relies on this. We bump the clientlayer version so that we can just
check for that version to know whether it's safe to use the base rpmdb.
