I find myself often wanting to debug interactively failing tests.
This makes it more convenient to keep around the temporary directories
just for those tests, rather than accumulating tons of tempdirs from
the successful tests as well.

The fact that we weren't doing this is at best an oversight, and
for some deployment models a security vulnerability. Having both
`gpg-verify` and `gpg-verify-summary` shows that we were intending
them to be orthogonal/independent.
Lately I've been advocating moving towards pinned TLS instead of
gpg-signed summaries, and if we follow that path, performing GPG
verification of commit objects even if using deltas is more important,
as it provides an at-rest verifiable authenticity and integrity
mechanism.
Content providers which are signing their summary files and/or using
TLS (particularly pinned TLS) for transport should treat this as a
nice-to-have. However, for providers which are serving content over
plain HTTP and relying on GPG, this is a critical update.

`-fsanitize=address` complained that the `refcount > 0` assertions
were reading without atomics. We can fix this by reworking them
to read the previous value.

It turns out this is basically racy with the presence of other
threads. It was really cosmetic so let's stop doing it and make
`-fsanitize=thread` happy.

This is actually fine in practice, but it triggers this
`-fsanitize=undefined` warning I saw in the test suite log:

You'd expect
ostree commit --tree=ref=A --tree=ref=B
to produce a commit with the union of the trees given. Instead you'd get
a commit with the contents of just the latter commit. This was due to an
optimisation where we'd skip filling out the `files` and `subdirs`
members of the mtree, just filling in the metadata instead. This backfires
becuase this same code relies on checking the `files` and `subdirs` members
itself to work out whether the mtree is empty.
This commit removes the optimisation, fixing the bug. Maybe there's a way
to keep the optimisation and still fix the bug but it's not obvious to
me.

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.
Closes: #576

For Project Atomic, we already have RPM signatures which use files in
`/etc/pki/rpm-gpg`. It's convenient to simply bind the OSTree remote
configuration to those file paths, rather than having duplicate key
data.
This does mean that we need to parse the files for verification, so we
end up importing them into the verifier's temporary keyring, which is
a bit ugly, but it's what other projects do.

When doing commit --tree=ref=XXX while at the same time applying some
form of modifier, ostree dies trying to read the xattrs using the
raw syscalls. We fix this by falling back to ostree_repo_file_get_xattrs()
in this case.
Also adds a testcase for this.
Closes: #577

What in the code is called "scanning" is ensuring (potentially
recursively) have an object, and if not, fetching it. And then if
it's metadata, parsing it and finding new objects to fetch.
This logic has grown fairly complex. What I'm trying to fix
right now is that if we're doing a pull-local to a remote repository
via `sshfs` (FUSE) we still end up scanning, which is inefficient.
We can take advantage of the "commitpartial" logic here - if a commit
isn't partial, it's complete, hence we don't need to scan it.
At the same time, I'm changing the logic here to *always* do scans for
dirtree objects. This will fix cases where multiple commits share
dirtree objects. We have "commitpartial" metadata, but no such concept
of partial/complete for dirtrees.
But, we'll only ever scan dirtrees if we scan commits, which is
what the section above fixes.

Some deployments may want to gate access to content based on things
like OAuth. In this model, the client system would normally compute a
token and pass it to the server via an API.
We could theoretically support this in the remote config too, but
that'd be a bit weird for OAuth as the information is dynamic.
Therefore this cleans up the code a little bit to more clearly handle
the case that the fetcher is initialized from both remote config
data plus pull options.

Otherwise it's possible for us to exhaust available file descriptors
or (on 32 bit) run up against mmap limits.
In the rollsum case, we didn't need to hold open the "from" object
at all. And in the bsdiff case, we weren't even looking at either of
the files until we started processing.
Also, while we have the patient open, switch to using O_TMPFILE
if available.

Private Cloudfront instances return 403 for objects which don't exist
rather then a 404.
Change the fetcher to assume 403 is ok for download that are "optional"
rather then erroring out at that step (e.g. trying to download a static
delta if the remote repo doesn't have those)

We should just download the commit objects directly, as it's
obviously a lot more efficient than deltas.

I was doing a chain of mirroring like A -> B -> C
And repo B had A as a remote. When I added B as
a remote to C, the summary file of B had a ref
upstream:foo/bar/baz, which caused all pulls from
B to C to fail, since the summary file is only
expected to have refs, not refspecs.

The cleanup attribute doesn't clean up before calling a noreturn
function like exit(). Explicitly clean up the pointer variables
(but don't assume that a simple g_object_unref() would be OK either,
in case the behaviour of the cleanup attribute changes).
This isn't a real leak since we're about to exit anyway, but if we
don't fix it then valgrind memcheck will make the tests fail.

Improve the heuristic to use only the part before the first '.' when
looking for a similar file in the current directory.
last versions of dracut generate reproducible initramfs files, but we
still fallback to the full file download if there is any minimal
change that causes a different checksum and file name.
This change extends that case to deal better with similar files that
have a different suffix.
