We need our `make install` to override the ostree RPM, so do it all in one txn.
This sort of thing is where a more rigorous model like rdgo/gcontinuous use
becomes better, but we'll hack it with shell for now.

`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.

Previously it was static to ostree-repo.c. Make it usable throughout
libostree so it can be used by an upcoming commit, but also expose the
typedef and reference counting functions so that opaque OstreeRemote
pointers can be used by user code, in anticipation of exposing more of
its API publicly in future.

global symbol list iff configured with --enable-experimental-api.
Distributions should not package OSTree with --enable-experimental-api.

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

If a summary metadata key is well-known, like ostree.static-deltas, or
ostree.summary.last-modified, format it a little more nicely.
This is especially important for timestamps like last-modified, since
otherwise they’re formatted as a big-endian uint64, which is basically
unusable for the user.
Non-formatted output can still be retrieved using the OSTREE_DUMP_RAW
flag, and the non-formatted key name is always printed for clarity.

• Commit timestamps, so it’s easy to work out whether a given commit is
newer than the one we have locally
• Summary file timestamp, so it’s easy to work out whether the summary
file is more up to date than another summary file
• Summary file expiry time, so clients can work out when they should
expect the summary file to next be updated, and hence can query for
it at roughly the right time
The expiry time requires input from the user, so is currently never set
automatically. Programs using libostree can set it if they wish.

If one of the progress keys is set in a pull operation, a ::changed
signal is emitted on the progress object, and the callback for that
could query any of the progress keys — so they all need to be set,
otherwise we get an assertion failure in ostree_async_progress_get() due
to a named key not existing.

g_date_time_new_from_unix_utc() will not always return a valid GDateTime

Use the new well-known `status` key for OstreeAsyncProgress to get and

Closes: #819
Approved by: cgwalters
Rework how the status is handled in OstreeAsyncProgress so that it’s now
a well-known key in the hash table. This means that it can be retrieved
and set atomically with other keys using
ostree_async_progress_[get|set]().
The behaviour of ostree_async_progress_[get|set]_status() is preserved,
with the caveat that `status` can now also be accessed using the other
API on OstreeAsyncProgress, and has to be accessed with the right
GVariant type.
Internally, a NULL status is represented by an empty status string
(since ostree_async_progress_[get|set]_variant() deliberately don’t
allow NULL variants to be set against keys, since that would break the
ostree_async_progress_get() API).

OstreeAsyncProgress is thread-safe: it can have keys changed by one
thread while another is getting the same keys (modulo some locking
contention). However, the thread safety is done at the function call
level: if some code calls an OstreeAsyncProgress getter several times,
the key fetches are not atomic with respect to each other.
In the case of contention on the lock, this can result in consumers of
OstreeAsyncProgress data seeing an inconsistent state between the
properties they query, which could result in progress reporting
inaccuracies.
In the uncontested case, this results in the OstreeAsyncProgress lock
being locked and unlocked many times more than necessary.
Try to improve this by adding new API, which supports getting and
setting multiple keys atomically:
• ostree_async_progress_get()
• ostree_async_progress_set()
The new API uses GVariants and varargs: keys are passed as a
GVariantType string followed by arguments as for g_variant_new() or
g_variant_get(), followed by the next key, etc.

OstreeAsyncProgress currently does some contortions to try and avoid
allocating space for guints and guint64s (on 64-bit platforms), but this
means it uses two GHashTables. A GHashTable allocates 8 buckets even
when empty. Given that the largest usage of OstreeAsyncProgress in
libostree puts 13 uints and 5 uint64s in it, this optimisation does not
save significant (if any) memory.
Instead, change OstreeAsyncProgress to store values internally as
GVariants, and expose this with some new API:
• ostree_async_progress_get_variant()
• ostree_async_progress_set_variant()
Each GVariant is allocated on the heap. As they are immutable, they are
thread-safe once returned by a getter.
The existing API continues to work as before, except in the case where a
key is set/got as both a uint and a uint64 — there will now be a
collision (and a GVariant type checking failure) whereas previously
there was no collision. Nothing in OSTree uses OstreeAsyncProgress this
way though.
The new API can be used to share more complex data via the progress API.

This was part of the philosophy behind https://wiki.gnome.org/Initiatives/GnomeGoals/InstalledTests -

can use the tests from our dependencies directly too.

Instead of using G_OPTION_ARG_STRING, use G_OPTION_ARG_FILENAME, which
handles filename encoding conversion differently from the locale
conversion which G_OPTION_ARG_STRING. This will fix argument handling on
systems where the filename encoding is not the same as the locale
encoding (which is fairly unlikely since most systems use UTF-8).

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()`.

installed, but in practice is oriented around unit (uninstalled, unprivileged)
tests.
