This allows specifying gpgpath as list of
paths that can point to a file or a directory. If a directory path
is given, paths to all regular files in the directory are added
to the remote as gpg ascii keys. If the path is not a directory,
the file is directly added (whether regular file, empty - errors
will be reported later when verifying gpg keys e.g. when pulling).
Adding the gpgkeypath property looks like:

When falling back to copying objects when importing them into a
bare-user repo, we only actually need to transfer over the
`user.ostreemeta` xattr.
This allows the destination repo to be on a separate filesystem that
might not even support `security.selinux`. (I hit this while importing
over virtio-9p).

I personally am very opposed to the entire idea of `make distcheck`;
I think source code should canonically be *git* and not tarballs.
See e.g. https://github.com/cgwalters/git-evtag for some
rationale.
But anyways we are uploading classic tarballs since today that
what Debian/Fedora/etc consume sadly, so we need to test it.
We explicitly skip `make distcheck` since we don't want to rerun
the test suite.

Wrap the `Version` key in the YAML-compatible output of
`ostree --version` with quotes so that it's parsed as a string. The
issues with the previous approach in a nutshell:
```
In [5]: yaml.load("asdf: 2018.10")
Out[5]: {'asdf': 2018.1}
```
It's treating the version number as a floating-point. Now, this is
technically a backwards incompatible change, but given that the previous
approach is inherently broken for our needs, I don't see a way around
breaking it now.

This renames a config key to make its semantics more obvious. Despite
what the commit message says, it only applies when a set of repo finders
is not specified (either on the command line or in a library API call).
This also renames the corresponding ostree_repo_get function. We can do
this since it hasn't been released yet.

Rather than manually starting the `ostree-finalize-staged.service` unit,
we can leverage systemd's path units for this. It fits quite nicely too,
given that we already have a path we drop iif we have a staged
deployment.
To give some time for the preset to make it to systems, we don't yet
drop the explicit call to `systemctl start`. Though we do make it
conditional based on a DEBUG env var so that we can actually test it in
CI for now. Once we're sure this has propagated, we can drop the
`systemctl start` path and the env var together.

This commit disables searching on the local network for refs, unless
explicitly requested by the user either by changing the value of the
"core.repo-finders" config option, or by passing an OstreeRepoFinderAvahi to
ostree_repo_find_remotes_async() / ostree_repo_finder_resolve_async(),
or by specifying "lan" in the --finders option of the find-remotes
command.
The primary reason for this is that ostree_repo_find_remotes_async()
takes about 40% longer to complete with the LAN finder enabled, and that
API is used widely (e.g. in every flatpak operation). It's also probable
that some users don't want ostree doing potentially unexpected traffic
on the local network, even though everything pulled from a peer is GPG
verified.
Flathub will soon deploy collection IDs to everyone[1] so these code
paths will soon see a lot more use and that's why this change is being
made now.
Endless is the only potential user of the LAN updates feature, and we
can revert this patch on our fork of ostree. For it to be used outside
Endless OS we will need to upstream eos-updater-avahi and
eos-update-server into ostree.

Currently libostree essentially has two modes when it's pulling refs:
the "legacy" code paths pull only from the Internet, and the code paths
that are aware of collection IDs try to pull from the Internet, the
local network, and mounted filesystems (such as USB drives). The problem
is that while we eventually want to migrate everyone to using collection
IDs, we don't want to force checking LAN and USB sources if the user
just wants to pull from the Internet, since the LAN/USB code paths can
have privacy[1], security[2], and performance[3] implications.
So this commit implements a new repo config option called "repo-finders"
which can be configured to, for example, "config;lan;mount;" to check
all three sources or "config;mount;" to disable searching the LAN. The
set of values mirror those used for the --finders option of the
find-remotes command. This configuration affects pulls in three places:
1. the ostree_repo_find_remotes_async() API, regardless of whether or
not the user of the API provided a list of OstreeRepoFinders
2. the ostree_repo_finder_resolve_async() /
ostree_repo_finder_resolve_all_async() API
3. the find-remotes command
This feature is especially important right now since we soon want to
have Flathub publish a metadata key which will have Flatpak clients
update the remote config to add a collection ID.[4]
This effectively fixes https://github.com/flatpak/flatpak/issues/1863
but I'll patch Flatpak too, so it doesn't pass finders to libostree only
to then have them be removed.

[3] Based on how long the "ostree find-remotes" command takes to
complete, having the LAN finder enabled slows down that step of the
pull process by about 40%. See also

Previously, we were preparing the root very late in the boot process;
right before we switch root. The issue with that is that most services
in the initrd that run `After=initrd-root-fs.target` expect that
`/sysroot` already points to the rootfs we'll be pivoting to. Running
this late violates that assumption.
This patch fixes this by making `ostree-prepare-root.service` instead
run right after `sysroot.mount` (the physical sysroot mounted by
systemd) but still before `initrd-root-fs.target` (which is the target
signalling that `/sysroot` is now valid and ready).
This should make it easier to integrate OSTree with other initrd
services such as Ignition.

Basically for people on e.g. rotational media, the default 90
second timeout can be too small.
We're in a tough situation here, because delaying shutdown
can be problematic too if the user is trying to shut down their
laptop to put in a backpack, etc.
There's potential optimizations here to make; I think we
could pre-copy the kernel/initramfs for example.
I suspect for some people the grub2 os-prober is a factor here too,
if that tries to e.g. inspect attached USB rotational hard drives.
But hopefully we'll get rid of that soon.

I was debugging some rpm-ostree work and saw:
`openat: No such file or directory`

Use the `err` API which is better in many ways; in this case
it automatically prefixes with `argv0`.

The idea is that if the process is running as root, it can change
ownership of newly written files to match the owner of the repo.
Unfortunately, it currently applies in the other direction, too - a
non-root user writing to a root owned repository. If the repo is
writable by the user but owned by root, it can still create files and
directories there, but it can't change ownership of them.
This feature comes from
https://bugzilla.gnome.org/show_bug.cgi?id=738954. As it turns out, this
feature was never completed. It only works on content objects and not
metadata objects, refs, deltas, summaries, etc. Rather than try to fix
all of those, remove the feature until someone has interest in
completing it.

Actually testing the patch to add `--force-copy-zerosized` to
rpm-ostree tripped over the fact that it uses `--union-identical`,
and we just hit an assertion failure with that combination.
Fix this by copying over the logic we have for the hardlink case.
Closes: #1753
Approved by: jlebon
In rpm-ostree we've hit a few cases where hardlinking zero-sized
files causes us problems. The most prominent is lock files in
`/usr/etc`, such as `/usr/etc/selinux/semanage.LOCK`. If there
are two zero-sized lock files to grab, but they're hardlinked,
then locking will fail.
Another case here is if one is using ostree inside a container
and don't have access to FUSE (i.e. `rofiles-fuse`), then the
ostree hardlinking can cause files that aren't ordinarily hardlinked
to become so, and mutation of one mutates all. An example where
this is concerning is Python `__init__.py` files.
Now, these lock files should clearly not be in the tree to begin
with, but - we're not gaining a huge amount by hardlinking these
files either, so let's add an option to disable it.

This commit removes the recommendation in the create-usb man page for
the user to update the summary in the source repo before using the
create-usb command. I'm not sure where I got the idea that create-usb
depends on a summary in the source repo. I went back to the first commit
that introduced the create-usb command and even using that a summary
isn't required, so it seems unlikely that this changed recently.
This is good news because the exclusive lock that's taken for summary
updates has been causing problems on Endless (due to other processes
having a lock for the duration of the 30 second acquire time out
period).

There are use cases for libostree as a local content store
for content derived or delivered via other mechanisms (e.g. OCI
images, RPMs, etc.). rpm-ostree today imports RPMs into OSTree
branches, and puts the RPM header value as commit metadata.
Some of these can be quite large because the header includes
permissions for each file. Similarly, some OCI metadata is large.
Since there's no security issues with this, support committing
such content.
We still by default limit the size of metadata fetches, although
for good measure we make this configurable too via a new
`max-metadata-size` value.

Currently the locking code checks if the value -1 was set for the config
key "lock-timeout-secs" and if so, a thread trying to acquire a lock
will block indefinitely. Positive values specify how long to attempt to
acquire a lock in a non-blocking way (the attempt is made once every
second). But when the value is read from the config file,
g_ascii_strtoull() is used, which converts it to an unsigned integer.
This commit makes libostree use g_ascii_strtoll() instead, so that it's
possible to set that key to -1 as intended.

Currently on Endless OS, the OSTree ref for the operating system is
something like os/eos/amd64/eos3, so that's what gets passed to `ostree
create-usb` when copying the OS to a USB drive (for offline updates).
However, when eos-updater checks for updates it pulls the metadata for a
candidate commit and in so doing updates that eos3 ref to point to the
partial commit being examined as a potential update rather than the
deployed commit. This causes `ostree create-usb` to fail with an error
like "No such metadata object
7fb045cb2d1f1f3a81bfc157c6128ff443eb56350315b9536bdb56aee0659863.dirtree".
OSTree creates deployment refs that look like "ostree/1/1/0" to maintain
a pointer to the deployed commit, but create-usb can't use these because
it shows up in the summary as just a ref, not a collection-ref.
So this commit adds a --commit option to the create-usb command, so we
can use the appropriate ref but copy the deployed commit rather than a
(potentially partial) update commit.

Copying the xattrs on metadata objects is wrong in general, we
don't "own" them. Notably this would fail in the situation of
doing a pull from e.g. a `bare-user` source to a destination
that was on a different mount point (so we couldn't hardlink),
and the source had e.g. a `security.selinux` attribute.
Closes: #1734Closes: #1736

Change the create-usb command so that it always creates the destination
repository using the "archive" mode, rather than using archive mode when
xattrs aren't supported and bare-user otherwise. This has a few
advantages:
1. The archive mode works with FAT filesystems, which is what most
USB drives are, and which doesn't support xattrs.
2. At least in some quick testing I did, archive mode is about
twice as performant as bare-user mode, in terms of how long it takes for
the create-usb command to complete.
3. This ensures that a tool can safely change the permissions on
".ostree/repo" and subdirectories after create-usb completes, which is
important for Endless since otherwise you can't use `ostree create-usb`
as root and then `flatpak create-usb` as a non-root user on the same USB
drive (or in other words copy OS updates and apps to the same USB).
