It turns out that librpm automatically merges identical files between
distinct packages, and this occurs in practice with Fedora today between
`chkconfig` and `initscripts` for exmaple.

let's change the semantics to do a merge. While we're here rename
to `UNION_IDENTICAL`.

Steal some code from flatpak for this, which allows porting a few more things to
new style. I started on a public API version of this but was trying to roll some
other things into it and it snowballed. Let's do this version since it's easy
for now.
While here I changed things so that `generate_deployment_refs()` now just uses
`_set_ref_immediate()` rather than requring a txn.
Also, AFAICS there was no test coverage of `generate_deployment_refs()`; I tried
commenting it out and at least `admin-test.sh` passed. Add some coverage of this
- I verified that with this commenting out bits of that function cause the test
to fail.

For rpm-ostree, I want to move RPM files in `/boot` to `/usr/lib/ostree-boot`.
This is currently impossible without forking the libarchive code. Supporting
this is pretty straightforward; we already had pathname translation in
the libarchive code, we just need to expose it as an option.
On the command line side, I chose to wrap this as a regexp. That should be good
enough for a lot of use cases; sophisticated users should as always be making
use of the API. Note that this required some new `#ifdef LIBARCHIVE` bits to use
the new API. Following previous patterns here, we use the new API only if a
relevant option is enabled, ensuring unit test coverage of both paths.
For the test cases, I ended up changing the accounting to avoid having to
multiply the test count.

`vmlinuz`. Also just best practice to have file suffix types where they make

This is the new Fedora kernel standard layout; it has the advantage
of being in `/usr` like `/usr/lib/ostree-boot`, but it's not OSTree
specific.
Further, I think in practice forcing tree builders to compute the checksum is an
annoying stumbling block; since we already switched to e.g. computing checksums
always when doing pulls, the cost of doing another checksum for the
kernel/initramfs is tiny. The "bootcsum" becomes more of an internal
implementation detail.
Now, there is a transition; my current thought for this is that rpm-ostree will
change to default to injecting into both `/usr/lib/ostree-boot` and
`/usr/lib/modules`, and stop doing `/boot`, then maybe next year say we drop the
`/usr/lib/ostree-boot` by default.
A twist here is that the default Fedora kernel RPM layout (and what's in
rpm-ostree today) includes a kernel but *not* an initramfs in
`/usr/lib/modules`. If we looked only there, we'd just find the kernel. So we
need to look in both, and then special case this - pick the legacy layout if we
have `/usr/lib/modules` but not an initramfs.
While here, rework the code to have an `OstreeKernelLayout` struct which makes
dealing with all of the variables nicer.

In the production case since we used `daemon()` our stderr is `/dev/null`¹
there's not much use in logging errors from `FITHAW` or `exit(1)`, and doing so

we can really do if `FITHAW` fails, and in most of those cases `EINVAL`,
`EOPNOTSUPP`, we *shouldn't* do anything anyways.

I'd like to move the new canonical kernel directory to `/usr/lib/modules/$kver`,
as Fedora has done. The `get_kernel_from_tree()` function now abstracts over
parsing the data (src vs destination filenames, as well as checksum) in
preparation for adding the new case.

*current* directory of `/usr/lib/ostree-boot`, and also add coverage of `/boot`.

XFS doesn't flush the journal on `syncfs()`. GRUB doesn't know how to follow the
XFS journal, so if the filesystem is in a dirty state (possible with xfs
`/boot`, extremely likely with `/`, if the journaled data includes content for
`/boot`, the system may be unbootable if a system crash occurs.
Fix this by doing a `FIFREEZE`+`FITHAW` cycle. Now, most people
probably would have replaced the `syncfs()` invocation with those two
ioctls. But this would have become (I believe) the *only* place in
libostree where we weren't safe against interruption. The failure
mode would be ugly; nothing else would be able to write to the filesystem
until manual intervention.
The real fix here I think is to land an atomic `FIFREEZETHAW` ioctl
in the kernel. I might try a patch.
In the meantime though, let's jump through some hoops and set up
a "watchdog" child process that acts as a fallback unfreezer.

(Note this PR was reverted in <https://github.com/ostreedev/ostree/pull/902>;
this version should be better)
Using `${sysroot}` to mean the physical storage root: We don't want to write to
`${sysroot}/etc/ostree/remotes.d`, since nothing will read it, and really
`${sysroot}` should just have `/ostree` (ideally). Today the Anaconda rpmostree
code ends up writing there. Fix this by adding a notion of "physical" sysroot.
We determine whether the path is physical by checking for `/sysroot`, which
exists in deployment roots (and there shouldn't be a `${sysroot}/sysroot`).
In order to unit test this, I added a `--sysroot` argument to `remote add`.
However, doing this better would require reworking the command line parsing for
the `remote` argument to support specifying `--repo` or `--sysroot`, and I
didn't quite want to do that yet in this patch.
This second iteration of this patch fixes the bug we hit the first time;
embarassingly enough I broke `ostree remote list` finding system remotes.
The fix is to have `ostree_repo_open()` figure out whether it's the same
as `/ostree/repo` for now.
Down the line...we might consider having the `ostree remote` command line itself
instatiate an `OstreeSysroot` by default, but this maximizes compatibility; we
just have to pay a small cost that `ostree` usage outside of that case like
`ostree static-delta` in a releng Jenkins job or whatever will do this `stat()`
too.
