a195888b0f lib/checkout: Fix regression in subpath for regular files
This is what caused the merge of
https://github.com/projectatomic/rpm-ostree/pull/652
to blow up, since https://github.com/ostreedev/ostree/pull/848
landed right before we tried to merge it.

When I was writing that PR I remember having an uncertain feeling
since we were doing a `mkdirat` above, but at the time I thought
we'd have test suite coverage...turns out we didn't.

For backwards compatibility, we need to continue to do a `mkdirat` here of the
parent. However...I can't think of a reason anyone would *want* that behavior.
Hence, let's add a special trick - if the destination name is `.`, we skip
`mkdirat()`. That way rpm-ostree for example can open a dfd for `/etc` and avoid
the `mkdir`.

Fold the subpath tests into `test-basic.sh` since it's not worth a separate
file. Add a test case for checking out a file.

b83d509e78 tree-wide: Switch tabs ⭾ in various files over to spaces ␠
As $DEITY intended.

I was reading the `prepare-root.c` code and the indentation damage was
distracting. Squash tabs that have leaked into various places in the code. I
didn't yet touch the `src/libostree` bits as that has higher potential for
conflict.

63497c65f3 checkout/commit: Use glnx_regfile_copy_bytes() if possible
Rather than `g_output_stream_splice()`, where the input is a regular
file.

See https://github.com/GNOME/libglnx/pull/44 for some more information.

I didn't try to measure the performance difference, but seeing the
read()/write() to/from userspace mixed in with the pointless `poll()` annoyed me
when reading strace.

As a bonus, we will again start using reflinks (if available) for `/etc`,
which is a regression from the https://github.com/ostreedev/ostree/pull/797
changes (which before used `glnx_file_copy_at()`).

Also, for the first time we'll use reflinks when doing commits from file-backed
content. This happens in `rpm-ostree compose tree` today for example.

48d2637e98 tests: Migrate test-pull-many.sh to installed on FAH
`test-pull-many.sh` is was just too slow to be a unit test.  Generating
a bunch of files via shell is slow, the delta generation is slow, etc.
Every developer doesn't need to run it every time.

Somewhat address this by converting it into our installed test framework, which
moves it out of the developer fast paths.  Another advantage to this is
that we can simply reuse the FAH tree content rather than synthesizing
new bits each time.

c7efe01520 Add --enable-installed-tests=exclusive, fix installed case
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.

e8efd1c8dc checkout: Add SELinux labeling for checkout, use in deploy
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()`.

b9df96db8b pull: Support deltas for explicit commits
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.

305db981d4 Add Coccinelle usage: one for blacklisting, one for patch collection
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.

455cc5e892 repo+tests: Add [core]disable-xattrs=true, use it on overlayfs
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.

a787e0c072 pull: Use all available commits for delta sources
The previous logic for static deltas was to use as a FROM
revision the current branch tip.  However, we want

here is to search it, and find the newest commit
we have locally that matches the TO revision target.

361aa449fb libcurl backend
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.

ecf5c079ea tests: Add setup for more realistic repo, change pull-many to use
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.

5c940987e7 Add support for more selective pruning
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.
