Some use cases for checkouts don't need to fsync during checkout.
Installer programs for example will just do a global fsync at the end.
In the future, the default "ostree admin" core could also be
rearchitected to only do a transaction commit right before reboot, and
do the fsync then.

This is just an efficiency optimization. We're getting fairly close
to all of the hot code paths using `*at()`.
Note that we end up maintaining a half-duplicate code path set here,
because we still need to support commits from an arbitrary GFile *,
which in a possible common case is an OSTree commit.
I think it's worth it though.
rpm-ostree had code to check for this, which didn't actually work.
I don't see a no backwards compatibility concern in changing this, as
it's unlikely a caller would try to sensibly disambiguate FAILED.
We were already using openat() for the contents, but not the xattrs.
Now that libgsystem 2014.3 has gs_fd_get_all_xattrs(), make use of it.
Clean things up a bit so we only open the fd once.
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.

ostree_repo_pull_with_options() needs this, and I'd rather keep the
OstreeRemote struct definition tucked away in ostree-repo.c with its
own internal API.
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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=741125
Applying xattrs on a symlink during checkout failed since
it was setting the xattrs on the final filename, not the
temporary name.
This made the "checkout union 1" test in test-basic.sh
fail.

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.

rpm-ostree at least has the option to generate a tree with just that
instead of /boot, but while we were enumerating the latter, we'd still
return paths from /boot.

In Anaconda, we're using "ostree admin --sysroot=/mnt/sysimage
instutil set-kargs", and it was working before, but newer versions of
lorax strip out /etc/system-release which grub2 wants.
That was wrong anyways as we want the /etc/system-release from the
target root.
(Man, grub2 sucks...give me a declarative config file format I can just
write)

Make _ostree_fetcher_request_uri_with_partial_async and
ostree_fetcher_stream_uri_async simple wrapper around the same
function, all the requests are created in the same place now.

Use the pattern:
$PRETTY_NAME [$COMMIT_VERSION] (ostree[:$OSNAME][:$DEPLOYMENT_INDEX])
$OSNAME is only shown if there are multiple values.
$COMMIT_VERSION refers to the version tag in the commit's metadata.
$DEPLOYMENT_INDEX is only shown if no $COMMIT_VERSION is available.

We potentially need a lot of argument types for pull. Rather than
have a C function with tons of arguments, let's use a GVariant a{sv}
as a handy extensible (and immutable) bag of properties.
This is prepratory work for adding an option to pull to traverse
history.
