And in general, if for some reason we can't write `user.` xattrs, provide an
error immediately rather than doing it during a later pull. This way the failure
cause is a lot more obvious.

In the storage PR I was trying to do a `pull-local` of the whole
`/ostree/repo` on the system, which ended up triggering a `g_critical()`
in the collections code, since we tried to parse a remote-prefixed ref
`fedora:fedora/26/x86_64/atomic-host` as a ref.
I'm not sure offhand what our behavior in this case *should* be. I
think git only clones local refs, but I need to check.
This corner case arises only with `pull-local`. But in any case,
while we were previously saying this is programmer error, since it's
so easy to pass various unchecked input into the pull machinery,
make invalid refs an explicit error.

For ostree-as-host, we're the superuser, so we'll blow past
any reserved free space by default. While deltas have size
metadata, if one happens to do a loose fetch, we can fill
up the disk.
Another case is flatpak: the system helper has similar concerns
here as ostree-as-host, and for `flatpak --user`, we also
want to be nice and avoid filling up the user's quota.

Some of the Jenkins jobs for Fedora Atomic Host broke after updating
to 2017.7, and it turns out that we regressed handling unreadable
files in `bare-user` mode. An example of this is `/etc/shadow`, which
ends up in the ostree-as-host content as `/usr/etc/shadow`.
Now there are better fixes here; we should probably delete it and create it
during the config merge if it doesn't exist. In general, having secret files in
ostree really isn't supported, so it doesn't make sense to include them.
But let's fix this regression - when operating as an unprivileged user we don't
have `CAP_DAC_OVERRIDE` and hence will fail to open un-user-readable objects.
(We still preserve the actual `0` mode of course in the xattr and will
apply it in `bare`)

Previously, we only supported additions in the statoverride file;
it was mainly for adding the setuid bit without having that physically
on disk.
However, for testing a change to `bare-user` handling around *unreadable*
files (which happens for `/etc/shadow` in host content), I need a way
to write that into a repo in the test suite.
I'm not actually aware of a non-test-suite use case for this; a more
sophisticated user is going to be using the API directly, which can already do
this. But we need it for tests at least.

I had thought `glnx_link_tmpfile_at()` actually consumed the tmpfile;
it does consume the *path* but not the fd. In the non-delta path
things were fine since we used the autocleanup.
But the delta code had a tmpfile allocated in its struct that got reused, and
hence leaked the fd. Fix this by making the commit API actually consume the
tmpfile fully, just like the path path.

This is a lot like `git clone --reference`, but we chose "localcache" as the
term "reference" is already used.
The main use case I'm targeting this for is the Fedora Atomic Host installer
case where we embed the repo content in the installer, but we may want to
kickstart and download newer content. There, while we want to get a newer ref,
we can still use the local repo as an object cache, since we have it sitting
there in memory anyways.
Another case is where one has a host ostree (say e.g. Fedora Atomic
Workstation), and one wants to create a local archive mirror of FAH. Then one
can use `pull --reference /ostree/repo` and pull the common objects (e.g.
contents of `bash.rpm` etc.)

There's lots of mechanically replacing `OtTmpFile` with `GLnxTmpfile`;
the biggest changes are in the commit path. Symlink commits are now
very clearly separated from regular files. Symlinks are `OtCleanupUnlinkat`,
and regular files are `GLnxTmpfile`.
The commit codepath separates those as `_ostree_repo_commit_path_final()` and
`_ostree_repo_commit_tmpf_final()`. A nice aspect of all of this is that they
both *consume* the temporary on success. This avoids an extra spurious
`unlink()` call.
One of the biggest bits of code motion is in `commit_loose_regfile_object()`,
which no longer needs to care about symlinks. For the most parth though it's
just removing conditionals.

This is an option which is intended mostly for flatpak;

We're adding an option for pulling into *all*
repo modes that has an effect similar to the `bare-user-only`
change from https://github.com/ostreedev/ostree/pull/909

ensure that there aren't any setuid or world-writable files.
Closes: #926
Approved by: alexlarsson
Thinking about the problem of flatpak converting from `bare-user` to `bare-user-only`
"in place" by creating a new repo and doing a `pull-local`, I realized
that we can optimize this process by doing hardlinks for both metadata
and regular files. The repo formats are *almost* compatible, the
exception being symlinks.
An earlier patch caused us to do hardlinks for metadata, this patch takes things
to the next step and special cases this specific conversion. In this case we
need to parse the source object to determine whether or not it's a symlink.
Closes: #922
Approved by: alexlarsson
Our previous logic for import-via-hardlink only tried if the repo modes match,
but we *can* hardlink metadata between e.g. `archive` and `bare-user` repos, and
that's quite useful thing to do. Our documentation encourages converting to/from
those repo modes locally for build systems.
Closes: #922
Approved by: alexlarsson
Before this, if one had repos of matching mode but different owners,
which could happen if one e.g. makes a `bare` non-root repo in
`/ostree/deploy/$stateroot/var/tmp`, every time we tried to call `linkat()`
we'd get `EPERM` and fall back to a copy.
Fix this by saving the repo owner uid, and avoid trying to call `linkat()` if we
know it's going to fail. Of course most commonly in this scenario we'll
immediately fail trying to `chown` the files to `0`, but this is prep for a
future patch to improve `bare-user` → `bare-user-only` imports where we'll be a
bit more sophisticated.

to have world-writable dirs. Particularly with the presence of the system
helper.
An approach I considered instead was to parse and validate directory metadata
objects at commit time. We still may do that in addition; for file objects we *had*
to do it that way because the actual files would be laid down suid. But directories
live only as inert `.dirmeta` objects until we do a checkout (i.e. `mkdir()`), so
we can solve the problem at checkout time.

for `bare-user` what we did for `bare-user-only` in
https://github.com/ostreedev/ostree/pull/909
It's also a stronger version of what we do with `checkout -U` in suppressing
suid - here we also strip world-writable files and the sticky bit (even though
that's meaningless today, it might not be in the future).

This is only used internally (the header is not public), so it doesn’t
have to go in ostree-autocleanups.h. It will be used in some following
commits.

If there are no deltas to be listed in the summary file, don’t bother
including the key for them in the additional metadata section of the
file. This saves a few bytes in some cases.

This follows on from commit a946c3d4, which added formatting for
well-known summary metadata keys. This commit adds it for commits.
Currently, the only well-known commit metadata key is
ostree.commit.timestamp. Formatting this correctly is especially
important, since it’s a big-endian uint64, which is completely unusable
for mere mortals when presented as a number rather than a date.
Non-formatted output can still be retrieved using the OSTREE_DUMP_RAW
flag, and the non-formatted key name is always printed for clarity.
