There are currently no unstable APIs, but some will be added in
following commits. They will be built and exposed in the libostree
global symbol list iff configured with --enable-experimental-api.
Distributions should not package OSTree with --enable-experimental-api.
This is designed for previewing new APIs on controlled platforms; any of
the APIs hidden behind this option may be changed or removed at any
point.

The major reason to do this is that running tests *both* installed
and uninstalled in our CI is a mostly pointless waste of time.
Particularly given we have a few expensive tests.
We *do* have tests that only run uninstalled (since they require
the source code) like `test-symbols.sh`.
Hence, add `--enable-installed-tests=exclusive` to mean *only* do installed for
most tests.
We'll still have uninstalled coverage via the Travis/Debian configs, and we
could perhaps do another build with a subset of uninstalled tests, but I'm not
really concerned about it.
I'd like to do a renewed push for the InstalledTests model since
I feel it's just fundamentally better. (`g-d-t-r` kind of sucks,
but then so does the automake runner).
Also while we're here - fix the CI to use the correct context,
which started this mess.

There were some regex special characters in the pattern strings, which I
think were causing the test to fail on some Travis builds due to using
an invalid regex.
Fix that by matching using fixed strings instead. We don’t need regexes
here. Use a new assert_file_has_content_literal to do that for us.

This is a variant of the efforts in https://github.com/ostreedev/ostree/pull/741
Working on `rpm-ostree livefs`, I realized though I needed to just
check out *new* files directly into the live `/etc` (and possibly
delete obsolete files).
The way the current `/etc` merge works is fundamentally different from
that. So my plan currently is to probably do something like:
- Compute diff
- Check out each *new* file individually (as a copy)
- Optionally delete obsolete files
Also, a few other things become more important - in the current deploy code, we
copy all of the files, then relabel them. But we shouldn't expose to *live*
systems the race conditions of doing that, plus we should only relabel files we
checked out.
By converting the deploy's /etc code to use this, we fix the same TODO item
there around atomically having the label set up as we create files. And further,
if we kill the `/var` relabeling which I think is unnecessary since Anaconda
does it, we could delete large chunks of code there.
In the implementation, there are two types of things: regular files, and
symlinks. For regular files, in the `O_TMPFILE` case, we have the ability to
do *everything* atomically (including SELinux labeling) before linking it into
place. So let's just use that. For symlinks, we use `setfscreatecon()`.

This could be shared more easily with e.g. rpm-ostree, but what I'm currently
working on is installed, privileged (potentially destructive, i.e. VM) tests
that will source this separately from the current `libtest.sh`. That does work
installed, but in practice is oriented around unit (uninstalled, unprivileged)
tests.

We really have an astonishing variety of similar functions which write files and
symlinks. I was working on a different PR and the duplication between the
union-mode and add-mode/none-mode checkout functions bothered me.
I realized that the "handle EEXIST" tri-state maps directly to the
`GLnxLinkTmpfileReplaceMode`, so deduping things makes even more sense.

I think the majority of OSTree usage calls pull with refs, not
explicit commits. We even added special "override syntax" with
`@` (e.g. `ostree pull foo@ab12c34`) as a hybrid.
However, some users may want to still pull explicit commits
for whatever reason. The old static delta logic looked at
the previous commit of the ref. However, in https://github.com/ostreedev/ostree/pull/710
we enhanced the logic to look at all local commits.
It's now a lot more natural to teach the delta logic
to support revisions, e.g. `ostree pull someorigin ab12c34`.
This also fixes the problem that before, `--require-static-deltas`
was completely ignored when processing revisions.
This is a nontrivial refactoring of the logic, but the end
result feels a lot more readable to me.

Previously we'd assert and dump core if one used `checkout -H` without
`-U` on a bare-user repo, because we'd hit the bare-user symlink case.
Rework the code to handle this, and add tests. I hit this when I was going to
suggest to someone to use `-H` to ensure they were getting hardlinks.

This is inspired by the [Coccinelle](http://coccinelle.lip6.fr/) usage
in systemd. I also took it a bit further and added infrastructure
to have spatches which should never apply. This acts as a blacklist.
The reason to do the latter is that coccinelle is *way* more powerful than the
regular expresssions we have in `make syntax-check`.
I started with blacklisting `g_error_free()` directly. The reason that's bad is
it leaves a dangling pointer.

This is somewhat complicated by such repos only properly supporting
some subset of file metadata (uid/gid 0, etc). We fix this by

There are a lot of things suboptimal about this approach, but
on the other hand we need to get our CI back up and running.
The basic approach is to - in the test suite, detect if we're on overlayfs. If
so, set a flag in the repo, which gets picked up by a few strategic places in
the core to turn on "ignore xattrs".
I also had to add a variant of this for the sysroot work.
The core problem here is while overlayfs will let us read and
see the SELinux labels, it won't let us write them.
Down the line, we should improve this so that we can selectively ignore e.g.
`security.*` attributes but not `user.*` say.

At least in all Linux kernels up to today, one can never `link()` across

The previous logic for static deltas was to use as a FROM
revision the current branch tip. However, we want
to support deltas between branches in an automatic
fashion.
If a summary file is available, we already have an
enumerated list of deltas - so the logic introduced
here is to search it, and find the newest commit
we have locally that matches the TO revision target.
This builds on some thoughts from

In https://github.com/ostreedev/ostree/pull/408, we disabled the use of
static deltas when mirroring. Later,
https://github.com/ostreedev/ostree/pull/506 loosened this up again so
that we could use static deltas when mirroring into bare{-user} repos.
However, the issue which originally spurrred #408 is even more generic
than that: we want to avoid static deltas for any archive repo, not just
when doing a mirror pull. This patch tightens this up, and also
relocates the decision code to make it easier to read.

For rpm-ostree, we already link to libcurl indirectly via librepo, and
only having one HTTP library in process makes sense.
Further, libcurl is (I think) more popular in the embedded space. It
also supports HTTP/2.0 today, which is a *very* nice to have for OSTree.
This seems to be working fairly well for me in my local testing, but it's
obviously brand new nontrivial code, so it's going to need some soak time.
The ugliest part of this is having to vendor in the soup-url code. With
Oxidation we could follow the path of Firefox and use the
[Servo URL parser](https://github.com/servo/rust-url). Having to redo
cookie parsing also sucked, and that would also be a good oxidation target.
But that's for the future.

As OSTree has evolved over time, the tests grew with it. We
didn't start out with static deltas or a summary file, and the
tests reflect this.
What I really want to do is change more of the pull tests, from
corruption/proxying/mirroring etc. to use this more realistic
repo rather than the tiny one the other test creates.
We start by using some of the code from `test-pull-many.sh`, and change that
test to use `--disable-static-deltas` for pull, since the point of that test is
to *not* test deltas.
Still TODO is investigate changing other tests to use this.

This would be more likely to tickle things like

Also, while working on the curl backend, I hit on the fact that curl doesn't
queue (by default, you can enable) and will happily create 20000+ concurrent TCP
connections if you try. Having this test would have made that more likely to
fail.

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.

Working on the libcurl backend, I hit the issue that the trivial-httpd program
depends on libsoup. I briefly considered having two versions, but libcurl is
client only, and moreover trivial-httpd is no longer trivial - it has various
features which are used by the test suite extensively.
Hence, what we'll do is build it as a separate binary which links to libsoup,
and use it during the tests. We *also* currently still provide `ostree
trivial-httpd` since some things use it like `rpm-ostree-toolbox` and the
Cockpit tests.
After those are ported to use some other webserver, I plan to add a build-time
option to drop it.
