Colin Walters 5c940987e7 Add support for more selective pruning
There are use cases for having a single repo with branches
with different lifecycles; a simple example of what I was
trying to do in CentOS Atomic Host work is have "stable"
and "devel" branches, were we want to prune devel, but
retain *all* of stable.

This patch is split into two parts - first we add a low level "delete all
objects not in this set" API, and change the current prune API
to use this.

Next, we move more logic into the "ostree prune" command. This paves the way for
demonstrating how more sophisticated algorithms/logic could be developed outside
of the ostree core.

Also, the --keep-younger-than logic already lived in the commandline, so it
makes sense to keep extending it there.

Alexander Larsson d0e74cf3af Fix pruning of partial commits
If we have a partial commit it is not an error for a dirmeta to be
missing (in fact, that is likely), so instead of returning a not-found
error from ostree_repo_traverse_commit() we ignore the error and
continue.

In particular, this means we don't stop early at the first
missing dirmeta, which previously caused ostree_repo_prune() to
thing the dirmetas after that to be unreached and thus purged.

Also, we remove the special casing in ostree_repo_prune() to
not report errors for commitpartial, because these should not
be reported anymore.

This fixes https://github.com/ostreedev/ostree/issues/541

Colin Walters 3ef4cc2e5b lib: Add an API to list only "our" objects, fix prune to use it
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`.

Dan Nicholson 31240982e7 core: Add verbose messages for pruning
When prune fails, it can be really difficult to figure out why. This at
least lets you know which objects are being considered.

Dan Nicholson 2ae7f619b2 prune: Don't fail on partial commits
If a commit only pull has been done, then the commit object exists in
the object store in addition to the commitpartial file. Traversing this
partial commit will likely fail, but that's expected. If traverse
returns a G_IO_ERROR_NOT_FOUND in this case, continue with pruning.

Colin Walters 18530894c7 libglnx porting: Use glnx_shutil_rm_rf_at()
In some cases (such as `ostree-sysroot-cleanup.c`), the surrounding
code would be substantially cleaner if it was also ported to
fd-relative, but I'm going to do that in a separate patch.

That way these patches are easier to review for mechanical
correctness.  I used an Emacs keyboard macro as the poor man's
[Coccinelle](http://coccinelle.lip6.fr/).

Extract existing code from ostree_repo_prune and add an argument COMMIT,
that controls which commit purge.  If not set, the old behavior is kept.

Colin Walters 279308b5b9 core: Cleanup commitpartial file with fd-relative lookups
First, this is just a general continuation of the `GFile -> openat`
transition.

Second, it's preparatory work for fsck to gain awareness of partial
commits.

Anne LoVerso 3742c32945 repo-pull: Allow pulling only one directory
Changes the pull API to allow pulling only a single directory instead
of the whole deployment.  This option is utilized by the check-diff
option in rpm-ostree.

Add a new state directory to hold <checksum>.commitpartial files, so
we know that we've only downloaded partial state.

Colin Walters 72da2e0c36 core: Unify object deletion code with prune
The prune API duplicated logic to delete objects, and furthermore the
core API to delete an object didn't clean up detached metadata.

Fix the duplication by doing the obvious thing: prune should call
_delete.

Colin Walters ac2d61dd51 core: Add detached metadata, readd metadata to commits
Previously I thought we'd have to ditch the current commit
format to avoid a{sv} due to

See https://bugzilla.gnome.org/show_bug.cgi?id=673012

But I realized that we don't really have to care about
unpacking/repacking commit objects, so let's just re-expose the
existing metadata a{sv} in commits in the API.

Also, add support for "detached" metadata that can be updated at any
time post-commit.  This is specifically designed for GPG signatures.
