If ostree-prepare-root is run as pid 1 (i.e we're not using an initramfs), then
anything we write outside the target sysroot (such as `/run/ostree-booted`) will
be lost.
Since `ostree-remount.service` runs fairly early in boot, and is triggered via
`ConditionKernelCommandLine=ostree`, we can just touch the file there in
addition.

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.

In ostree_repo_abort_transaction, if we pass a cancellable and it gets
canceled, then the function may fail to fully clean up the transaction
state. This was happening e.g. when the ostree_repo_pull_with_options
call got cancelled.
To fix this, as suggested by Colin Walters, we set the passed
cancellable as NULL, in order for it to be ignored.

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.
By default the payload-link-threshold value is G_MAXUINT64 that disables
the feature.

The original changes here apparently had the *idea* that `--static-deltas-only`

If we're booted into a deployment, then any queries for the pending

OstreeRepoFinderMount checks mounts for a few well-known directories
such as "ostree/repo" and ".ostree/repo" to try to find remotes. One of
the hard-coded directories is "var/lib/flatpak" but that's the flatpak
directory, not the ostree repo used by flatpak, which is at
"var/lib/flatpak/repo". So this commit changes the path so the repo can
be found.
For recent versions of Endless, flatpak uses /ostree/repo as its
repository, so this commit won't make a difference there. But it may
help on other operating systems.

The `admin` commandline should be considered a demo; I just added
the `pin` command *mostly* so we could use it for unit tests, although
I can imagine other people using it.
But maintaining completions is a lot of overhead right now, let's not
do it for `admin`.
The other command line options that operate on repos we will definitely maintain

Example user story: Jane rebases her OS to a new major version N, and wants to
keep around N-1 even after a few upgrades for a while so she can easily roll

The `origin/unlocked` and `origin/override-commit` keys are examples of state
that's really transient; we don't want to maintain them across upgrades. Right
now there are bits for this in both `ostree admin upgrade` as well as in
rpm-ostree.
This new API will slightly clean up both cases, but it's really prep for adding
a concept of deployment "pinning" that will live in the new
`libostree-transient` group.

Since f4d1334e19 the primary pull code maintains a
maximum queue. In that commit message I said `Note that I kept an assertion.`.
But I think this is wrong since while it covers a lot of the normal cases, if
one is e.g. trying to fetch a ton of refs, the primary pull code doesn't yet
queue those. While it'd be nice to queue those, it isn't worth carrying
extra assertions in the backends that can still trigger.

There are a few cases for knowing whether a commit has identical
content to another commit. Some people want to do a "promotion workflow",
where the content of a commit on a tesitng branch is then "promoted"
to a production branch with `ostree commit --tree=ref`.
Another use case I just hit in rpm-ostree deals with
[jigdo](https://github.com/projectatomic/rpm-ostree/issues/1081) where we're
importing RPMs on both the client and server, and will be using the
content checksum, since the client/server cases inject different metadata
into the commit object.

For P2P pulls ostree adds temporary remotes and removes them in
find_remotes_cb(). However, if an OstreeRepoFinderResult gets freed
during the course of that function, the OstreeRemote in the result is
freed but a pointer to it remains in the remotes_to_remove array. This
means that when _ostree_repo_remove_remote() gets called on it at the
end of the function it will fail. In my case the resulting error was
"OSTree-CRITICAL **: _ostree_repo_remove_remote: assertion 'remote->name
!= NULL' failed" but I think it could also seg fault.
This commit adds a reference to the remote so it can be properly removed
when we're finished with it.

This is analogous to the filtering support for the commit API: we allow
library users to skip over checking out specific files. This is useful
in some tricky situations where we *know* that the files to be checked
out will conflict with existing files in subtle ways.
One such example is in rpm-ostree support for multilib. There, we want
to allow checking out a package onto an existing tree, but skipping over
files that are not coloured to our preferred value (e.g. not overwriting
an i686 version of `ldconfig` if we already have the `x86_64` version).

SPDX License List is a list of (common) open source
licenses that can be referred to by a “short identifier”.
It has several advantages compared to the common "license header texts"
usually found in source files.
Some of the advantages:
* It is precise; there is no ambiguity due to variations in license header
text
* It is language neutral
* It is easy to machine process
* It is concise
* It is simple and can be used without much cost in interpreted
environments like java Script, etc.
* An SPDX license identifier is immutable.
* It provides simple guidance for developers who want to make sure the
license for their code is respected

This came up as a problem with `oci-umount` which was trying to ensure some host

since our `/sysroot` mount wasn't private we also got a copy there.

Currently users of the find_remotes_async()/pull_from_remotes_async()
functions have no way to specify a commit hash to use instead of the
latest one available. This commit implements an "override-commit-ids"
option analogous to the one used by ostree_repo_pull_with_options().
It's accomplished by returning OstreeRepoFinderResult objects pointing
to the given commit checksum(s) regardless of which ones were available
from the remotes, but in the future this implementation could be
improved to take into account the commits advertised by the remotes.
One effect of this is that flatpak will have the ability to downgrade
apps that use collection IDs
(https://github.com/flatpak/flatpak/issues/1309).

Much like the (optional) initramfs at
`/usr/lib/ostree-boot/initramfs-<SHA256>` or
`/usr/lib/modules/$kver/initramfs` you can now optionally include a
flattened devicetree (.dtb) file alongside the kernel at
`/usr/lib/ostree-boot/devicetree-<SHA256>` or
`/usr/lib/modules/$kver/devicetree`.
This is useful for embedded ARM systems which need the devicetree file
loaded by the bootloader for the kernel to discover and initialise
hardware. See https://en.wikipedia.org/wiki/Device_tree for more
information.
This patch was mostly produced by copy-pasting code for initramfs handling
and renaming `s/initramfs/devicetree/g`. It's not beautiful, but it is
fairly straightforward.
It may be useful to extend device-tree support in a number ways in the
future. Device trees dependant on many details of the hardware they
support. This makes them unlike kernels, which may support many different
hardware variants as long as the instruction-set matches. This means that
a ostree tree created with a device-tree in this manner will only boot on
a single model of hardware. This is sufficient for my purposes, but may
not be for others'.
I've tested this on my NVidia Tegra TK1 device which has u-boot running
in syslinux-compatible mode.
Closes: #1411

The bootloader spec says:
> `devicetree` refers to the binary device tree to use when executing the
> kernel. This also shall be a path relative to the `$BOOT` directory. This
> key is optional. Example:
> `6a9857a393724b7a981ebb5b8495b9ea/3.8.0-2.fc19.armv7hl/tegra20-paz00.dtb`
This is necessary for booting my NVidia Tegra TK1 device. It uses u-boot
with syslinux compatibility. In the syslinux files that come with the
device this is called `FDT`, but u-boot treats `FDT and `DEVICETREE` as
synonyms.
