static deltas: Use OtVariantBuilder to create deltas
This allows us to create the final delta desciptor directly on disk
rather than having it all in memory. This is nice because it can
become quite large if inlined parts are used.
Note however, that we currently generate all the delta parts in
memory before adding them to the delta, so we still keep all individual
parts in memory. Fixing that is the next step.
This is similar to GVariantBuilder in that it constructs variant
containers, but it writes it directly to a file descriptor rather
than keep the entier thing in memory. This is useful to create large
variants without using a lot of memory.

Before, if we found a devino cache hit, we'd use it unconditionally.
Recall that `bare-user` repositories are very special in that they're the only
mode where the on disk state ("physical state") is not the "real" state. The
latter is stored in the `user.ostreemeta` xattr. (`bare-user` repos are also
highly special in that symlinks are regular files physically, but that's not
immediately relevant here).
Since we now have `bare-user-only` for the "pure unprivileged container" case,
`bare-user` should just be used for "OS builds" which have nonzero uids (and
possibly SELinux labels etc.)
In an experimental tool I'm writing "skopeo2ostree" which imports OCI images
into refs, then squashes them together into a single final commit, we lost the
the `81` group ID for `/usr/libexec/dbus-1/dbus-daemon-launch-helper`.
This happened because the commit code was loading the "physical" disk state,
where the uid/gid are zero because that's the uid I happened to be using. We
didn't just directly do the link speedup because I was using `--selinux-policy`
which caused the xattrs to change, which caused us to re-commit objects from the
physical state.
The unit test I added actually doesn't quite trigger this, but I left
it because "why not". Really testing this requires the installed test
which uses SELinux policy from `/`.

lib/checkout: For "process whiteouts" mode, replace directories too
I'm playing around with some ostree ⇔ OCI/Docker bits, and ran
into this while importing an OCI image that built from the Fedora
base image where `/home` is a regular directory, and I added a layer
that did the ostree bits of moving it to `/var` and leaving a symlink.
OCI/Docker supports this. Now since "process whiteouts" is really the
"enable OCI/Docker" mode, let's only replace dirs if that's enabled.
This leaves the `UNION_FILES` targeted for its original use case
which is unioning components/packages. (Although that use case itself
is now a bit superceded by `UNION_IDENTICAL`, but eh).
One thing to note is when we parse the admin related functions,
we still keep the old admin related flags, and added a new parameter

easier for us to possibly deduplicate the subcommand handling in

lib/checkout: fallback to checksum for UNION_IDENTICAL
There's a subtle issue going on with the way we use `UNION_IDENTICAL`

This ends up causing issues like:
https://github.com/projectatomic/rpm-ostree/issues/1047
There, `vim-minimal` is already part of the host and has an object for
`/usr/share/man/man1/ex.1.gz`. `vim-common` has that same file, but
because it's unpacked in the pkgcache repo first, the hardlinks are not
the same.
There are a few ways we *could* work around this in rpm-ostree itself,
e.g. by re-establishing hardlinks when we do the content pull into the
system repo, but it still felt somewhat hacky. Let's just do this the
proper way and fall back to checksumming the target file if needed,

checksum if they're not hard links, but they're the same size.

modified.
One tricky bit that took me some time was that we now need to store the
st_dev & st_ino values in the GFileInfo because the cache lookup relies
on it. I'm guessing we regressed on this at some point.
This patch does slightly change the semantics of the xattr callback.
Previously, returning NULL from the cb meant no xattrs at all. Now, it
means to default to the on-disk state. We might want to consider putting
that behind a flag instead. Though it seems like a more useful behaviour
so that callers can only override the files they want to without losing
original on-disk state (and if they don't want that, just return an
empty GVariant).

libarchive: Fix assertion error if used with CANONICAL_PERMISSIONS
I was trying to do a change for rpm-ostree to use
`OSTREE_REPO_COMMIT_MODIFIER_FLAGS_CANONICAL_PERMISSIONS`
for container builds with `bare-user-only,` but hit an assertion here
ultimtely because we weren't setting `standard::type`.
Rather than hand-rolling `GFileInfo` creation, use the stat buffer conversion
code which is more robust and used in multiple places already.
