d5273b34d0 lib/repo: Add API to create and list ref aliases
There are multiple use cases where we'd like to alias refs.

First, having a "stable" alias which gets swapped across major
versions: https://pagure.io/atomic-wg/issue/228

Another case is when a ref is obsoleted;
<https://pagure.io/atomic-wg/issue/303>
This second one could be done with endoflife rebase, but I think
this case is better on the server side, as we might later change
our minds and do actual releases there.

I initially just added some test cases for symlinks in the `refs/heads` dir to
ensure this actually works (and it did), but I think it's worth having APIs.

455cc5e892 repo+tests: Add [core]disable-xattrs=true, use it on overlayfs
There are a lot of things suboptimal about this approach, but
on the other hand we need to get our CI back up and running.

The basic approach is to - in the test suite, detect if we're on overlayfs. If
so, set a flag in the repo, which gets picked up by a few strategic places in
the core to turn on "ignore xattrs".

I also had to add a variant of this for the sysroot work.

The core problem here is while overlayfs will let us read and
see the SELinux labels, it won't let us write them.

Down the line, we should improve this so that we can selectively ignore e.g.
`security.*` attributes but not `user.*` say.

02a2b689dd refs: resolve conflict between local/remote repos
Add the functionality to use the same name for refs in local and remote
repos. This helps users keep track of local refs of remote origin, much
like local and remote git branches.

Previously, when a local ref is specified, resolve_refspec would fall
back to searching through remote repos if the ref is not found locally.
This function now takes an extra flag to specify whether it should
search through remote repos. Additionally, ostree_repo_resove_rev_ext
was added to call resolve_refspec with fallback_remote being false, so
refs --create would no longer complain when trying to create a local
ref of the same name as a remote one.

Fix remote repo parsing not being handled correctly on refs --create.

744543110e refs: allow overwrite of empty folders
We noticed that once a ref folder is created, there is no existing
command that can remove it. For example, once "foo/bar" is created,
even if the user deletes foo or all the refs under foo, the folder
will persist.

Now when the user attempts to create a ref "foo" either through commit
or refs --create, if a folder "foo" exists but is empty of refs, the
folder is removed and the new ref "foo" is created.

New unit tests in tests-ref.sh verify this functionality.

f8fcdba0a5 refs: add "ostree refs --create" and unit tests
Added the ability to create a ref (much like a git tag) for an
existing commit through "ostree refs EXISTING --create=NEWREF".
Previously the only way to create a new ref was by creating a new commit,
but refs --create allows multiple refs to point to the same commit.

The command will fail if:
 - None/more than one existing ref is specified
 - The specified EXISTING tag does not exist, or was not specified
 - The specified NEWREF already exists, or is the name of a folder

Add unit tests in tests-ref.sh to verify above functionality

d25212f04a tests: Port to glib-tap.mk, make make check run all of the tests
OSTree's code for testing predates the `glib-tap.mk` making its
way into GLib.  Let's switch to it, as it provides a number
of advantages.

By far the biggest advantage is that `make check` can start to run
most of the tests *in addition* to having them work installed.

This commit keeps the installed tests working, but `make check` turns
out to be really broken because...our TAP usage has bitrotted to say
the least.  Fix that all up.

Do some hacks so that the tests work uninstalled as well - in
particular, `glib-tap.mk` and the bits encoded into
`g_test_build_filename()` assume *recursive* Automake (blah).  Work
around that by creating a symlink when installed to loop back.
