OSTree function ostree_repo_pull_with_options starts a
series of operations that makes heavy use of the PullData's
cancellable.
This isn't effective, however, since nowhere in the code
the OtPullData.cancellable field is set. This is visible,
for example, when trying to cancel a Flatpak pull and nothing
happens, because the cancellable is not properly passed
to the pull data.
Fix that by setting the cancellable field of the pull data. It
owns a reference for safety reasons, and unreferences it at the
end of the operation.

The `warn()` libc extension has exactly the same behaviour as our own
`perrorv` function, but is available in (at least) glibc and musl. As an
added bonus the similar function `err()` which will exit with an error
code afterwards.
This implementation is tidier and allows us to get rid of our own
`perrorv`. It paves the way to removing `ostree-mount-util.c` to simplify
the build scripts.

If the `--with-static-compiler=musl-gcc` configure flag is given.
ostree-prepare-root can be used as init in a system without a populated
/lib. To support this use case we need to link statically as we will be
unable to locate libc.so at run time if it's not installed in /lib.
We support building ostree-prepare-root with a different compiler to the
rest of ostree so we can use musl rather than glibc. This reduces the size
of the executable significantly: from ~700K -> ~30K. We have to use
`_SCRIPTS` here to get autotools to install this as an executable but
without generating rules to make it itself which we have specified
manually.
See https://lists.gnu.org/archive/html/help-gnu-utils/2007-01/msg00007.html
for advice on using autotools in this manner.

POSIX and GNU define conflicting versions of `strerror_r`. The GNU
version returns the string but doesn't necessilary write into buf.
The POSIX version writes into buf and returns the length but doesn't
necessilary append a terminate the string with a NUL if it's too long
to fit in buf.
This commit fixes building ostree-prepare-root with musl libc. The
stripped static build with musl on my machine is 30K vs. 724K with glibc
static and 11K with glibc shared.

We hold a fd open on this, and it's basically now expected
to be immortal. Confer that status.
This was showing up in flatpak crashers, because we'd get
an unexpected errno.
(I didn't test this fixes the crasher, but it's clearly right)

I noticed seeing the output of `prune` twice in rpm-ostree, and had
always wondered why. When reading the rpm-ostree code to fix
something else, reasons, I noticed the reason - we were pruning once
here, and then once after rpm-ostree regenerates its "base" refs.
There's no reason to clean twice, so let's add a flag so rpm-ostree
can suppress doing it inside libostree.

It's close-on-exec, not close-on-fork. I was clearly confused when
writing this; it works just fine to reference the fd in the child and
`fchdir()` before exec. So drop the unnecessary duplication.
Just noticed this while reading the code for a random other reason.

With this patch, an admin (system builder) can now:
1) Edit /usr/lib/ostree-boot/uEnv.txt
2) Deploy the new tree. OSTree will append system's uEnv.txt
to the OSTree's managed uEnv.txt (loader/uEnv.txt).
It is common for u-boot systems to read in an extra env
from external /uEnv.txt. The same file OSTree uses to pass
in its env. With this patch /uEnv.txt now contains OSTree's
env + custom env added by system builders.

When doing a prune, we should not try to delete objects in parent
repos, since it'll fail. There is a bigger discussion about the
semantics of `parent=` to be had, but this will fix trying to use
`ostree prune --repo=/ostree/repo/extensions/rpmostree/pkgcache`.

Programs like `useradd` try to `open(/etc/passwd, O_RDWR)` to append,
which didn't work with rofiles-fuse. Thinking about this, I realized
that there's a simpler algorithm for "can we write to this file" which
is "does it have a hardlink count <= 1"?
Switching to this both drops complexity (we no longer need to keep a
hash table of files we created), and also lets useradd work.

The test suite was actually doing something before, just
not quite what I intended. Without `-U` for bare-user checkouts
we end up doing a copy.
Now, a future commit will change how rofiles work, which would cause
the test suite to permit inplace mutation for non-hardlinked files.
So let's ensure they *are* hardlinked.

The documentation says this is ignored, implying that you should pass
NULL to it. However, the function immediately returns in this case even

Why not to use libexecdir?
Because this directory does not exist on some distros or paths
between distros varies. There are several reasons why a well
known path is prefered, for example when generating a kernel
command line:
init=${ostree}/usr/lib/ostree-boot/ostree-prepare-root
In addition this saves us some typing in a console when wanting
to access the "ostree" cmd line.

Pulls from local repos now default to disabling static deltas so that
objects are copied. To check this is the case, see if the object files
are hardlinked after pulling.
Closes: #447Closes: #448
Approved by: cgwalters
For local pulls there's no benefit pulling the static delta over the
individual object files since there's no HTTP overhead. Furthermore,
processing deltas always generates the objects whereas a standard pull
ensures that the exact object files are copied. Using deltas also
prevents hardlinking the objects if the repos exist on the same
filesystem.
Closes: #447Closes: #448
Approved by: cgwalters
When testing pulling of deltas, use the new --require-static-deltas
option to pull-local to ensure that deltas are actually used. To support
the require-static-deltas mode, the summary in the remote repo must be
generated.

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.

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.
