This made sense back when we used a main loop even when we needed to
fetch objects synchronously. Nowadays, we no longer actually update
progress before the FETCHING_OBJECTS phase, which is only for async
requests.
This allows us to get rid of fetch_uri_contents_membuf_sync() and to
generalize fetch_uri_contents_utf8_sync() so that it only requires a
fetcher. This will be needed later.

Allow users to pass a --contenturl during `remote add` and store it in
the remote config.
Fish out the contenturl setting from the remote config and use it when
downloading static deltas and objects (except for commit signatures).
The idea here is that items in the trust chain (summary & sigs) can be
fetched from a more secure e.g. TLS-pinned location, while objects
themselves are fetched from another location. Once mirrorlist support is
added, this use-case will become even more advantageous.

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.

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.

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

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.

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.

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.

This was the last use of libgsystem tmpfile APIs. The change here is
a bit uglier than it needs to be because we support creating the delta
in place as well as in the repo, so we needed to abstract over
locations.

Inlining this is uglier, but this code kind of sucks anyways =( We're
going to need to do some fd-relative porting in here at some point.

In one case, we already had relative fds and hence this was
nicer. Unfortunately the other areas got uglier. More fd-relative

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.

If a static delta is generated between 2 commits with the same content,
then the delta will contain 1 part with no checksums. While useless,
this is a valid delta that shouldn't raise an assertion. If the delta
part has no checksums, then there are no objects to recreate and the
processing can be skipped.

In general this is even cleaner now, though it was better after I

Closes: #369

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.

This one is a bit subtle; we're generating a hash that contains
