56a922280f tests: Port sysroot.js away from libgsystem
My case-sensitive `git grep` didn't find this one originally,
but the Travis+Debian setup was configured to run it.

a29bb0ab6b Final excision of libgsystem dependency
Lots and lots of preparation led to this moment - when nothing
apparent changes for users!  Woo!

But seriously, having the extra dependency is a minor annoyance, and
in the big picture I think the libgsystem idea was wrong - we need to
land things in GLib, and use git submodules for API-unstable or
Linux-specific sharing.  For a lot of OSTree, the libgsystem `GFile*`
orientation was also wrong, we really want fd-relative.

fd9536bb19 prune: Retain the tip of each ref even with date pruning
I hit an error with [CAHC](https://wiki.centos.org/SpecialInterestGroup/Atomic/Devel)
where we were doing time-based pruning.  `ostree summary -u` started failing,
and it took me a bit to realize it was because we were pruning
even the tip of old branches, which I was not at all expecting,
and I don't think users will too.

Perhaps in the future we could add some sort of --prune-ref-tips or
something if people wanted it, but I doubt it.

46e118ee84 travis: run the test suite on various distributions
.travis.yml is obviously still Travis-specific, but tests/ci-* are
designed to be shareable with other CI environments if there is interest
in doing so.

At the moment I'm only testing on Debian and Ubuntu. In principle we
could try a non-Debian-derived Docker container such as Fedora or CentOS
inside travis-ci's Ubuntu environment, similar to what I'm doing
for Debian, but I don't know the correct setup commands to use there.

593effe2fb lib: Add padding booleans to OstreeRepoCheckoutAtOptions
Since this is a new API, and adding booleans is the most likely thing
we'll do, let's stick some explicit padding for them in here now.

We could use the `unused_ints[]` but it'd be out of order, and this
will more clearly remind people about the padding.  The efficiency hit
versus bitfields is annoying, but oh well, not a real world problem.

47e7afab27 ostree-prepare-root: Refactor: Create /sysroot.tmp much later
Typically we have our ready made-up up root at
`/sysroot/ostree/deploy/.../` (`deploy_path`) and the real rootfs at
`/sysroot` (`root_mountpoint`).  We want to end up with our made-up root
at `/sysroot/` and the real rootfs under `/sysroot/sysroot` as systemd
will be responsible for moving `/sysroot` to `/`.

We need to do this in 3 moves to avoid trying to move `/sysroot` under
itself:

1. `/sysroot/ostree/deploy/...` -> `/sysroot.tmp`
2. `/sysroot` -> `/sysroot.tmp/sysroot`
3. `/sysroot.tmp` -> `/sysroot`

This is a refactoring to group all these operations together so I can
implement an alternative in terms of `pivot_root`.

94e50ca5aa tests: Add basic tests for ostree-prepare-root
These tests use unshare and mount to prepare a fake initrd/early boot
directory structure so we can then test ostree-prepare-root.

Things that are tested:

* Running in an initrd environment
* Running without initrd
* /var and /sysroot being mounted correctly
* /usr being mounted read-only

Things not tested (yet):

* Running as init - this could be accomplished by unsharing the pid
  namespace too.
* mounting/unmounting `/proc` if `/proc/cmdline` isn't available
* Persistent overlayfs for `/usr`
* Probably other things

The tests are basic but can be extended in the future as we do more work
on `ostree-prepare-root`.

These tests must be run as root as they require the ability to `mount`
and to `unshare` the mount namespace. Perhaps in the future we can use
user namespaces for this test once they are more widely available.

5334758ba7 repo: Make ostree_repo_create() nonfatal on existing repos
In general we want to support "idempotentcy" or "state
synchronization" across interruption.  If a repo is only partially
created due to a crash or whatever, it's hard for a user to know that.
Let's just make `ostree_repo_create()` idempotent. Since all we're
doing is a set of `mkdirat()` invocations, it's quite simple.

This also involved porting to fd-relative, which IMO makes the
code a lot clearer.

6ffcb24d22 deltas: Handle untrusted checksums faster and more robustly
When reworking the ostree core [to use O_TMPFILE](https://github.com/ostreedev/ostree/pull/369),
I hit an issue in the way the untrusted delta codepath ends up trying
to re-open the file to checksum it.  That's not possible with
`O_TMPFILE` since the fd (which we opened `O_WRONLY`) is the only
accessible reference to the content.

Fix this by changing the delta processing code to update a checksum as
we're doing writes, which is also faster, and ends up simplifying the
code as well.

What would be an even larger simplification here is if we e.g. used a
separate thread calling `write_object()` or something like that; the
main issue I see there is somehow bridging the fact that function
wants a `GInputStream*` but the delta code is generating stream of
writes.
