All components of the path are locked before the check, and
released once the path is already mounted.
This makes it impossible to replace the mounted directory until it's
actually mounted in the container.

All subpath components are opened with openat, relative to the base
volume directory and checked against the volume escape.
The final file descriptor is mounted from the /proc/self/fd/<fd> to a
temporary mount point owned by the daemon and then passed to the
underlying container runtime.
Temporary mountpoint is removed after the container is started.

`VolumeOptions` now has a `Subpath` field which allows to specify a path
relative to the volume that should be mounted as a destination.
Symlinks are supported, but they cannot escape the base volume
directory.

Instead of special-casing anonymous endpoints in libnetwork, let the

Rewrite `.build-empty-images` shell script that produced special images
(emptyfs with no layers, and empty danglign image) to a Go functions
that construct the same archives in a temporary directory.
Use them to load these images on demand only in the tests that need
them.

Copy the implementation of `context.WithoutCancel` introduced in Go 1.21
to be able to use it when building with older versions.
This will use the stdlib directly when building with Go 1.21+.

Integration tests will now configure clients to propagate traces as well
as create spans for all tests.
Some extra changes were needed (or desired for trace propagation) in the
test helpers to pass through tracing spans via context.

commit ab35df454d removed most of the pre-go1.17

As we have a hard time figuring out what moby/moby#46099 should look
like, this drop-in replacement will solve the initial formatting problem
we have. It's made internal such that we can remove it whenever we want
and unlike moby/moby#46099 doesn't require thoughtful API changes.

This sets BuildKit version from the build information embedded
in running binary so we are aligned with the expected vendoring.
We iterate over all dependencies and find the BuildKit one
and set the right version. We also check if the module is
replaced and use it this case.
There is also additional checks if a pseudo version is
detected. See comments in code for more info.

Starting the daemon should not load the busybox image again
in most cases, so add a new `StartNodeWithBusybox` function
to be clear that this one loads the busybox image, and use
`StartNode()` for cases where loading the busybox image is
not needed.
Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
The daemon was already created and started with the busybox
image loaded, so there's no need to load the image again.

While working on other tests I noticed that environment.Execution cannot
be used for anything but the pre-configured daemon, however this can
come in handy for being able share daemons across multiple tests that
currently spin up a new daemon.
The execution env also seems to be misused in some of these cases.

This is just noise due to timing. I picked `> 2` just based on

When connecting with the daemon using a UNIX socket, the HTTP hostname was set, based
on the socket location, which was generating some noise in the test-logs.
Given that the actual hostname is not important (the URL just has to be well-formed),
the hostname/address can be cleaned up to reduce the noise.
This patch strips the path from the `addr`, and keeps `<random-id>.sock` as address.

The test-integration/test=integration-cli directory contains
a directory for each daemon that was created during the integration
tests, which makes it a long list to browse through. In addition,
some tests spin up multiple daemons, and when debugging test-failures,
the daemon-logs often have to be looked at together.
This patch organizes the bundl directory to group daemon storage
locationos per test, making it easier to find information about
all the daemons that were used in a specific test.

This allows our tests, which all share a containerd instance, to be a
bit more isolated by setting the containerd namespaces to the generated
daemon ID's rather than the default namespaces.
This came about because I found in some cases we had test daemons
failing to start (really very slow to start) because it was (seemingly)
processing events from other tests.

This improves the select logic for the restart tests or starting the
daemon in general. With the way the ticker and select was setup, it was
possible for only the timeout to be displayed and not the wait errors.

Refactored exiting logic on way that layers are first marked to be under
removal so if actual removal fails they can be found from disk and
cleaned up.
Full garbage collector will be implemented as part of containerd
migration.
