Add more flexible _remote_change() API , expose via 'ostree remote'
For Anaconda, I needed OSTREE_REPO_REMOTE_CHANGE_ADD_IF_NOT_EXISTS,
with the GFile *sysroot argument to avoid ugly hacks. We want to
write the content provided via "ostreesetup" as a remote to the target
chroot only in the case where it isn't provided as part of the tree
content itself.
This is also potentially useful in idempotent systems management tools
like Ansible.

repo: Add private functions to access remote options
ostree_repo_pull_with_options() needs this, and I'd rather keep the

repo: Add an internal struct to manage remotes
OstreeRemote is a reference-counted struct that encompasses data about a
remote, whether read from a configuration file or created explicitly via
ostree_repo_remote_add().
OstreeRemotes are held in an internal table indexed by remote name.
This solves some problems caused by merging system-wide remote data into
the OstreeRepo's internal config key file.

Add local-pull archive-z2 <=> bare-user roundtrip test
This creates a archive-z2 repo, pull-locals it to bare-user and then
again back to archive-z2 making sure things fsck along the way.
Then it checks out all repos and makes sure each one reproduces
the same result.
Unfortunately we can't install this as a real test because
it doesn't work in the test-runner because tmpfs doesn't support
user xattrs.
This format is pretty much the same as the "bare" format, except the
file ownership and xattrs is not stored in the actual filesystem object, but
rather on the side in a user xattr. This means two things:
1) An unprivileged user can store such a repo independent of the types
of files in it or their xattrs. And you can later (as root)
reconstruct the real filesystem tree with ownership. Although you
can't do that using hardlink-sharing. This also means ostree
fsck does a full verification.
2) Such a repository can be checked out with user-mode (checkout -U)
as an unprivileged user using hardlinks for space sharing.
Additionally, symlinks are stored as regular files (with the content
being the symlink target) because user xattrs are not supported on
symlinks. We know at checkout time if the file is a symlink because
the original st_mode is stored in the xattr metadata.
When commiting a symlink we do store the uid/gid of the actual
symlink (i.e. not target). However, this was not restored
on non-user-mode checkout as it should.
This commit fixes that, and additionally it ensures xattrs
on symlinks are not set in user-mode checkout.

grub2: If using --sysroot, run in chroot
In Anaconda, we're using "ostree admin --sysroot=/mnt/sysimage

That was wrong anyways as we want the /etc/system-release from the

Add (non-atomic) support for GRUB2 + UEFI
We need basic support for UEFI - many newer servers don't support
BIOS compatibility mode anymore.
However, this patch only implements non-atomic because UEFI is FAT, and
we can't do the previous design for OSTree of atomic swap of
/boot/loader.
The Fedora/RHEL UEFI layout has the kernels on a "real" /boot
partition, and /boot/efi/EFI/$vendor just holds the grub2 UEFI binary
and grub.cfg.
Following this, /boot/loader is still on the OS boot partition, and we
still atomically swap it. This potentially paves the way to atomic
upgrades in the future.

repo: When writing to a non-root owned repo, chown() objects to match
Some package systems need to be run as root, so the process linking to

This patch makes it Just Work by chowning the file content to match.
Note this only operates on archive-z2 repositories, because you can't
usefully serve bare repositories via HTTP.

libostree: Add initial GRUB2 support
In this approach, we drop a /etc/grub.d/15_ostree file which is a
hybrid of shell/C that picks up bits from the GRUB2 library (e.g. the

GRUB2 code which knows about the BLS entries.

learn the BLS specification. However, the spec has a few issues:
