This way two pulls will not use the same tmpdir and accidentally
overwrite each other. However, consecutive OstreeFetchers will reuse
the tmpdirs, so that we can properly resume downloading large objects.

Concurrent pulls break since we're sharing the staging directory for
all transactions in the repo. This makes us use a per-transaction directory.
However, in order for resumes to work we first look for existing
staging directories and try to aquire an exclusive lock for them. If
we can't find any staging directory or they are all already locked,
then we create a new one.
https://bugzilla.gnome.org/show_bug.cgi?id=757611
This creates a subdirectory of the tmp dir with a selected prefix,
and takes a lockfile to ensure that nobody else is using the same directory.
However, if a directory with the same prefix already exists and is
not locked that is used instead.
The later is useful if you want to support some kind of resumed operation
on the tmpdir.

This is very useful for the inline-parts case, as you can then include
detached signatures in a single file representing the commit.
It is not as important for the generic pull case, as the detached
metadata is only a single small file. Additionally the detached
metadata is not content referenced and may change after the static
delta file was created, so we need to pull the latest version anyway.
If you pass a diriectory it will look for the "superblock" child, otherwise
it will use the file as the superblock. I need this in xdg-app to be able
to install any filename as a bundle.
Also renames OstreeRepoTrustedContentBareCommit to
OstreeRepoContentBareCommit so that it can be used by both.
This will be needed when we introduce checksum verification of objects
in static deltas.
In this mode the parts are stored in the metadata of the main delta
superblock file. This can be useful if you want a single-file delta
for easy transport, or for http in the case the delta is very small.
You create these with something like:
ostree static-delta generate --empty --to=master
These will be automatically used during pull if no previous revision
exists in the target repo.
These work very much like the normal static deltas except they
are named just by the "to" revision. I.e:
deltas/94/f7d2dc23759dd21f9bd01e6705a8fdf98f90cad3e0109ba3f6c091c1a3774d
for a from-scratch to 94f7d2dc23759dd21f9bd01e6705a8fdf98f90cad3e0109ba3f6c091c1a3774d delta.

The current layout uses a prefix of two bytes as the initial dir
and a second directory inside that with the superblock. This
updates the list code to handle that.

This creates a archive-z2 repo, pull-locals it to bare-user and then
again back to archive-z2 making sure things fsck along the way.
Then it checks out all repos and makes sure each one reproduces
the same result.
Unfortunately we can't install this as a real test because
it doesn't work in the test-runner because tmpfs doesn't support
user xattrs.
https://bugzilla.gnome.org/show_bug.cgi?id=741125
This just does whatever test-basic.sh does, but on a bare-user
repo.
This works standalone, but unfortunately it breaks in
gnome-desktop-testing-runner as /tmp doesn't support
xattrs, so it is not installed atm.
https://bugzilla.gnome.org/show_bug.cgi?id=741125
This format is pretty much the same as the "bare" format, except the
file ownership and xattrs is not stored in the actual filesystem object, but
rather on the side in a user xattr. This means two things:
1) An unprivileged user can store such a repo independent of the types
of files in it or their xattrs. And you can later (as root)
reconstruct the real filesystem tree with ownership. Although you
can't do that using hardlink-sharing. This also means ostree
fsck does a full verification.
2) Such a repository can be checked out with user-mode (checkout -U)
as an unprivileged user using hardlinks for space sharing.
Additionally, symlinks are stored as regular files (with the content
being the symlink target) because user xattrs are not supported on
symlinks. We know at checkout time if the file is a symlink because
the original st_mode is stored in the xattr metadata.
https://bugzilla.gnome.org/show_bug.cgi?id=741125
Applying xattrs on a symlink during checkout failed since
it was setting the xattrs on the final filename, not the
temporary name.
This made the "checkout union 1" test in test-basic.sh
fail.
https://bugzilla.gnome.org/show_bug.cgi?id=741125
When commiting a symlink we do store the uid/gid of the actual
symlink (i.e. not target). However, this was not restored
on non-user-mode checkout as it should.
This commit fixes that, and additionally it ensures xattrs
on symlinks are not set in user-mode checkout.
