There are use cases for having a single repo with branches
with different lifecycles; a simple example of what I was
trying to do in CentOS Atomic Host work is have "stable"
and "devel" branches, were we want to prune devel, but
retain *all* of stable.
This patch is split into two parts - first we add a low level "delete all
objects not in this set" API, and change the current prune API
to use this.
Next, we move more logic into the "ostree prune" command. This paves the way for
demonstrating how more sophisticated algorithms/logic could be developed outside
of the ostree core.
Also, the --keep-younger-than logic already lived in the commandline, so it
makes sense to keep extending it there.

Conceptually we've been moving towards having our GPG verification
paths be per-remote. The code internally supports this, but we
didn't expose an API to use it conveniently.
This came up when trying to add a new `gpgkeypath` option, since
right now rpm-ostree manually finds keyrings for the remote, and
hence it wasn't looking at the keypath, and said "Unknown key"
in status.
Adding an API fixes this nicely.

The checksum_b64_inplace variants can't be used in bindings. Provide
versions that allocate and return the output rather than working on a
passed in buffer. These can then be used in GI bindings to get the
ostree modified base64 encodings.

Add the functionality to use the same name for refs in local and remote
repos. This helps users keep track of local refs of remote origin, much
like local and remote git branches.
Previously, when a local ref is specified, resolve_refspec would fall
back to searching through remote repos if the ref is not found locally.
This function now takes an extra flag to specify whether it should
search through remote repos. Additionally, ostree_repo_resove_rev_ext
was added to call resolve_refspec with fallback_remote being false, so
refs --create would no longer complain when trying to create a local
ref of the same name as a remote one.
Fix remote repo parsing not being handled correctly on refs --create.

This can be useful for validating the 3rd party data that is put in
the extensions directory and is signed with the same keys as commits
or the summary file.

I plan to add a function for verifying any data which may return the
error about lack of trusted signatures, so let's avoid the redundancy
and put the check in the separate function.

It is quite similar to the already existing
ostree_raw_file_to_content_stream function, so I factored the common
part to a separate function. The difference is that we cannot report
the size of the resulting stream.
Can be useful for serving a "bare" repository as a faked "archive-z2"
repository.
Closes: #308

This adds a _with_options variant of the
ostree_repo_remote_fetch_summary function, so we can tell the fetcher
to use a specific URL instead taking it from the remote config.

We keep forgetting to update `apidoc/ostree-sections.txt`, so let's
start enforcing it. Of course it turns out we had some bugs here
like symbols marked as public but never implemented, etc. Those
are fixed in the prior commits.

These are useful for ostree users (like xdg-app) that have custom
options for remotes. In particular they are useful when we later make them
all respect self->parent_repo.

This can be used as a fingerprint to determine whether two

I'm trying to improve the developer experience on OSTree-managed
systems, and I had an epiphany the other day - there's no reason we
have to be absolutely against mutating the current rootfs live. The
key should be making it easy to rollback/reset to a known good state.
I see this command as useful for two related but distinct workflows:
- `ostree admin unlock` will assume you're doing "development". The
semantics hare are that we mount an overlayfs on `/usr`, but the
overlay data is in `/var/tmp`, and is thus discarded on reboot.
- `ostree admin unlock --hotfix` first clones your current deployment,
then creates an overlayfs over `/usr` persistent
to this deployment. Persistent in that now the initramfs switchroot
tool knows how to mount it as well. In this model, if you want
to discard the hotfix, at the moment you roll back/reboot into
the clone.
Note originally, I tried using `rofiles-fuse` over `/usr` for this,
but then everything immediately explodes because the default (at least
CentOS 7) SELinux policy denies tons of things (including `sshd_t`
access to `fusefs_t`). Sigh.
So the switch to `overlayfs` came after experimentation. It still
seems to have some issues...specifically `unix_chkpwd` is broken,
possibly because it's setuid? Basically I can't ssh in anymore.
But I *can* `rpm -Uvh strace.rpm` which is handy.
NOTE: I haven't tested the hotfix path fully yet, specifically
the initramfs bits.
This will allow daemons like rpm-ostree to detect if there are any new
deployments efficiently, in combination with using inotify. If there
are any changes, rpm-ostree wants publish them on DBus.
While we're here, add some changes to start doing unit C testing of
the sysroot API.
And change the command line to use it. rpm-ostree had a copy
of this code, and thus there's a clear reason to have an API.
While we're moving this into API, ensure the mtime on deploy is bumped
after an osname is created, so that daemons like rpm-ostree can notice
changes. (In reality, creating the directory should do this, but
let's be double sure)
It accepts a `flags` argument to control its behavior. Differently
from `ostree_repo_list_refs`, the `refspec_prefix` is not removed from
the results.

I plan to use this in rpm-ostree at least for two reasons:
- To find the mtime on the repo
- To use the tmp/ directory to stage content (but we should eventually
add a better API)
As rpm-ostree evolves, it keeps driving API additions to libostree.
This creates a relatively tight coupling.
However, if delivering via e.g. RPM, unless one manually remembers to
increment the `Requires:` in the spec file, it's possible for the two
to become desynchronized.
RPM handles versioned symbols and will ensure a dependency if the
application starts using a newer version.
To implement this, switch to `-fvisibility=hidden`, along with an
annotation in the header, and finally add a `.sym` file.
This matches what other projects like systemd and libvirt do.
Although rather than attempting to retroactively version symbols, glom
them all onto the current one.
