I hit a bit of a wall here around `gs_shutil_cp_al_or_fallback()`.
I guess we'll have to reimplement it here.
In the meantime, this gets us closer.

This is basically a re-implementation of
85c9dd5c07
for the same reasons: it makes things work for rpm-ostree running
inside NixOS. But there are other cases where if e.g. an unprivileged
user runs rpm-ostree and may not have `/usr/sbin` in PATH, we still
want the container to pick it up, etc.
While changing things I nuked the hacky `RPMOSTREE_DEBUG_SCRIPT` env
var, we can re-add it later in a better way if needed.

We have two different codepaths for creating a cache branch header
string, one from libdnf, and one from librpm. It turns out if
an RPM package explicitly specifies an `Epoch: 0` like various Fedora
perl subpackages do, these are different.
Explicitly convert `0:` to the empty string to make them match, and
hence installation will work.

Nothing in the file seems to use it. Doing this quickly via GitHub UI under assumption that the magic @walters bot will take care of running the full test suite, but otherwise I'll test it later when I get back to a machine I can use for that.

This makes the design fully coherent now - we don't try to store
multiple commits, we no longer reference them, and the cleanup does a
depth=0 pruning.

My desktop system was aborting on upgrade with a missing metadata
object, which turned out to be the fact that my previous changes to
the package layering code pruned with depth=0, but the commit it was
looking for had a parent commit that had been pruned.

I hit a pile of:
```
Oct 04 12:44:15 icarus.verbum.local rpm-ostreed[26257]: ostree_repo_resolve_partial_checksum: assertion 'error == NULL || *error == NULL' failed
```
Which turned out to be a missing metadata object (for some reason),
but this function's incorrect use of `ret = TRUE` caused the GError
to have already been set.
Fix this, and we change to "direct return" style which is more
readable.

Per OSTree design, /var can start out empty. However, our warning
spam here is annoying. Let's first delete some known files -
obviously this won't be exhaustive, but it's way faster than trying to
fix all of this in the packages right now.
The major one is the SELinux policy, which resulted in a lot of spam.

These were added to shadow-utils in recent times (Fedora 25 e.g.) and
like the other passwd files, shadow-utils opens them with `O_TRUNC`.
(At some point we should patch it to do create-new-then-replace internally)

It turns out it was buggy (for some reason `PS1` wasn't propagating),
and furthermore, things mostly work if one enables `--new-chroot` i.e.
`systemd-nspawn`, which is what Fedora is going to do, and everyone
else in the world uses Docker.
While we're here, tweak the error message to use `<>` around the URL
which makes it more easily clickable from terminals.

Communicating information is a hard problem, but basically there
are two things here. First, the changelogs make the diff visual
spaghetti. (If we were rendering to HTML with expanders or something,
it could work).
Second, I think RPM changelogs are legacy - tooling should pull from
git.
So far when doing release announcements I've been manually stripping
out the changelogs, embarassingly enough. Time to fix that.
Anyways, we preserve the changelog-emitting code, it's just not the
default now.

Currently, we do the final commit into the pkgcache repo, then
pull it to the base. The problem with this is that, combined
with the fact that we're not presently pruning the pkgcache repo,
we leak space.
In preparation for a cleaner fix for this, rework things so that the
core infra can know about *both* a base repo and a pkgcache repo. If
they're separate (as is the case for rpm-ostree-on-host), whenever we
are doing layering, explicitly pull just the `.file` objects that are
referenced into the parent repo. We do the final commit in the base
repo.

I hit this with librepo subbing out the $releasever with e.g. 7.2016.1
when trying to pull various URLs. It should be enough for the user to
see the ostree version in VERSION and PRETTY_NAME. For applications,
there's OSTREE_VERSION if they need just that.

`systemctl start/stop/try-restart` are all useless for us in
scripts, since changes should only affect the *next* boot.
`systemctl enable` is also wrong - one should use presets instead.
Currently, systemd has code to detect whether it's inside
a chroot, which works for mock, but *not* for Docker or bubblewrap.
(We should teach systemd a nicer way to disable itself, but
even if we did that we'd have to support old scripts)
So, this fixes layering `glusterfs` in CAHC.
Closes: #432

When executing scripts, map `/usr/lib/passwd` temporarily back to
`/etc/passwd` from the POV of the script, then move it back. This
allows client-side layered packages be merged with the base tree
version, while still being distinct from the `/etc/passwd`.
(In the future we'll likely rewrite all of this to use
`systemd-sysusers(8)`, but for now let's be incremental.)
Note in this commit it isn't very useful, because pretty much all RPMs
only call `useradd` in `%pre`, which is the next commit.
Closes: #432
Approved by: jlebon
Because OSTree includes numeric uid/gid, but package layering (and
traditional full-client-side RPM) expects to allocate UIDs on the
machine, we need to handle non-root owned files specially.
For files in /run and /var, we can convert them to
`systemd-tmpfiles(8)` snippets which will be executed at the next
boot, after a uid/gid has been assigned.
Closes: #432

Decided to test this on Sunday evening. Of course it was broken =(
(Actually I tested mock-in-Docker but it should be the same)
The core problem is that mock does `chroot()` without using `/`
as a mount point. This breaks an assumption in bwrap that it is.
Now, in theory we could move this same logic down into bwrap to
work around this situation, but for now let's hack it here.
Mock is old, legacy container code that doesn't really do anything
in a modern way - in fact our goal should be to replace it
with a combination of rpm-ostree and bwrap. So carrying this
hack here to get us to that future should be OK for now.

I want a better error message if the user happens to execute
inside e.g. a Docker container without sufficient privileges
for recursive containerization.
Closes: #429

The previous commit https://github.com/projectatomic/rpm-ostree/pull/422
introduced a regression in the "outside of a container" path - we
get `EINVAL` trying to `mount("proc",...)` and honestly I'm not sure why.
We can either back up or plow forward, and it turns out to be
pretty straightforward to complete the port to using bwrap.
I extracted the bwrap-execution code out of the RPM script engine,
because the treecompose model is currently different (no hardlinks
yet).
NOTE: A *very* important side effect of this is that we now
require "privileged" containers on hosts without user namespaces,
and on userns hosts, require `CLONE_NEWUSER` to be exported to the
container host.
In general though, the previous path of blindly executing scripts as root
without e.g. `proc` mounted was just bad.

The treecompose code will learn how to use bwrap instead of
libcontainer in libglnx, since the latter is a buggy copy of a subset
of the former.

If next_dent returns `FALSE`, we need to also return `FALSE` from
the function.
I just noticed this as I happened to be reading the code randomly.

Otherwise we try to execute as shell script which obviously doesn't
work. This was noticed when @dustymabe was trying to assemble
a Fedora container with `glibc-all-langpacks`.

I was looking at starting to unify the treecompose path to the
"new world" infrastructure in package layering. An initial
step here is to port to fd-relative, which cleans up the code.
Note this depends on a libglnx pull.
