sysroot: Rework how we find booted deployment

I was looking at this code in prep for "staging" deployments,
and there are several cleanups to be made here.  The first
thing I noticed is that we look for the `ostree=` kernel argument,
but the presence of that should be exactly equivalent to having
`/run/ostree-booted` exist.  We just added a member variable for
that, so let's make use of it.

Related to this, we were erroring out if we had the karg but
didn't find a deployment.  But this can happen if e.g. one is
using `ostree admin --sysroot` from an ostree-booted system!  It's
actually a bit surprising no one has reported this so far; I guess
in the end people are either using non-ostree systems or running
from containers.

Let's add a member variable `root_is_sysroot` that we can use
to determine if we're looking at `/`.  Then, our more precise
"should find a booted deployment" state is when both `ostree_booted`
and `root_is_sysroot` are TRUE.

Next, rather than walking all of the deployments after parsing,
we can inline the `fstatat()` while parsing.  The mild ugly
thing about this is assigning to the sysroot member variable while
parsing, but I will likely clean that up later, just wanted to avoid
rewriting everything in one go.

When a new object is added to the repository, create a
$PAYLOAD-SHA256.payload-link symlink file as well.  The target of the
symlink is the checksum of the object that was added the repository.

Whenever we add a new object file, in addition to lookup if the file is
already present with the same checksum we also check if an object with
the same payload is in the repository.

If a file with the same payload is already present in the repository, we
copy it with `glnx_regfile_copy_bytes` that internally attempts to
create a reflink (ioctl (..., FICLONE, ..)) to the target file if the
file system supports it.  This enables to have objects that share the
payload but have a different inode and xattrs.

lib: Validate metadata structure more consistently during pull

Previously we were doing e.g. `ot_util_filename_validate()` specifically inline
in dirtree objects, but only *after* writing them into the staging directory (by
default). In (non-default) cases such as not using a transaction, such an object
could be written directly into the repo.

A notable gap here is that `pull-local --untrusted` was *not* doing
this verification, just checksums.  We harden that (and also the
static delta writing path, really *everything* that calls
`ostree_repo_write_metadata()` to also do "structure" validation
which includes path traversal checks.  Basically, let's try hard
to avoid having badly structured objects even in the repo.

One thing that sucks in this patch is that we need to allocate a "bounce buffer"
for metadata in the static delta path, because GVariant imposes alignment
requirements, which I screwed up and didn't fulfill when designing deltas. It
actually didn't matter before because we weren't parsing them, but now we are.
In theory we could check alignment but ...eh, not worth it, at least not until
we change the delta compiler to emit aligned metadata which actually may be
quite tricky.  (Big picture I doubt this really matters much right now
but I'm not going to pull out a profiler yet for this)

The pull test was extended to check we didn't even write a dirtree
with path traversal into the staging directory.

There's a bit of code motion in extracting
`_ostree_validate_structureof_metadata()` from `fsck_metadata_object()`.

Then `_ostree_verify_metadata_object()` builds on that to do checksum
verification too.

All the current uses of the find-remotes command in the tests use it to
find configured remotes or mounted (USB) remotes, so using
--finders=config and --finders=mount in the tests respectively shouldn't

Support for booting without initramfs

Previously when initramfs-* was not found in a deployment's
boot directory, it was assumed that rootfs is prepared for
ostree booting by a kernel patch.

With this patch, the behaviour changes to be - if initramfs-*
is not found, assume that system is using a static
ostree-prepare-root as init process. Booting without initramfs

also more convenient, than having to patch the kernel.

ostree-prepare-root: enabler for simpler kernel arg

With the current approach, when ostree-prepare-root is used
on the kernel command line as init=, it always assumes that
the next value in the argument list is a path to the sysroot.
The code for falling back to a default path (if none is provided),
would only work if init= is the last arg in the argument list.
We can not rely on that and have to explicitly provide the
path to the sysroot. Which defeats the purpose of a default
path selection code.

To keep command line neater assume that sysroot is on / when
using ostree-prepare-root as init. This probably is what most
people want anyways. Also _ostree_kernel_args* API assumes
that args are space separated list. Which is problematic for:
"init=${ostree}/usr/lib/ostree/ostree-prepare-root /" as it

bin/commit: add --keep-metadata option

Clients of libostree such as rpm-ostree make extensive use of the
`ostree commit -b foo --tree=ref=foo` pattern in their tests, e.g. to
simulate an update.

What I'm trying to solve here is that it's often the case that we want
to keep metadata from the previous commit without having to be too
verbose (i.e. reading from the parent, then passing it as an argument).

The new `--keep-metadata` switch makes this really easy. I intend to use
this in the rpm-ostree testsuite to make sure we always carry over the
`source-title` metadata as well as during set up for tests that require
`rpmostree.rpmdb.pkglist` metadata.

I initially implemented this in a small wrapper script that uses the API
directly, though we make use of so many other `ostree commit` functions
that it'd require re-implementing a lot of it.
