Fix a corner case in basic_setup(), where we rmi stray images.
If a test tags $IMAGE and fails to rmi by tag name, cleanup
could rmi both tag name and IID, wiping out the desired image:
podman tag $IMAGE foo
...
cleanup: rmi foo $FOO_IID [this removes $IMAGE!]
Solution: rmi by name, but only rmi by IID if != $IMAGE.
TOTH to ypu for bringing this to my attention.

is not added to $PATH for rootless users. This will break rootless

Instead of creating an extra container create a network and mount
namespace inside the podman user namespace. This ns is used to
for rootless cni operations.
This helps to align the rootless and rootful network code path.
If we run as rootless we just have to set up a extra net ns and
initialize slirp4netns in it. The ocicni lib will be called in
that net ns.
This design allows allows easier maintenance, no extra container
with pause processes, support for rootless cni with --uidmap
and possibly more.
The biggest problem is backwards compatibility. I don't think
live migration can be possible. If the user reboots or restart
all cni containers everything should work as expected again.
The user is left with the rootless-cni-infa container and image
but this can safely be removed.
To make the existing cni configs work we need execute the cni plugins
in a extra mount namespace. This ensures that we can safely mount over
/run and /var which have to be writeable for the cni plugins without
removing access to these files by the main podman process. One caveat
is that we need to keep the netns files at `XDG_RUNTIME_DIR/netns`
accessible.
`XDG_RUNTIME_DIR/rootless-cni/{run,var}` will be mounted to `/{run,var}`.
To ensure that we keep the netns directory we bind mount this relative
to the new root location, e.g. XDG_RUNTIME_DIR/rootless-cni/run/user/1000/netns
before we mount the run directory. The run directory is mounted recursive,
this makes the netns directory at the same path accessible as before.
This also allows iptables-legacy to work because /run/xtables.lock is
now writeable.

The 'is' check was intended to be called with three arguments,
the last one being a nice helpful test name. There's a fallback
for two-argument calls, but it was a horrible FIXME.
New fallback: the most recently run podman command. We keep
track of it in each run_podman() invocation.
This is not ideal, because it's theoretically possible to
invoke 'is' on something other than the output of run_podman,
but this at least fixes the by-far-most-common case.

Since podman-remote resize requests can come in at random times, this
generates a real potential for race conditions. We should only be
attempting to resize TTY on running containers, but the containers can
go from running to stopped at any time, and returning an error to the
caller is just causing noice.
This change will basically ignore requests to resize terminals if the
container is not running and return the caller to success. All other
callers will still return failure.

If you are attempting to run a container in interactive mode, and want
a --tty, then there must be a terminal in use.
Docker exits right away when a user specifies to use a --interactive and
--TTY but the stdin is not a tty.
Currently podman will pull the image and then fail much later.
Podman will continue to run but will print an warning message.

- cp test: clean up stray image
- build test: add workaround for #9567 (ultra-slow ubuntu).
We're seeing CI flakes (timeouts) due to ubuntu 2004 being
absurdly slow. Workaround: double our timeout on one specific
test when ubuntu + remote.
- build test: clean up new copy-from test (from #9275).
The test was copy-pasted from buildah system tests, without
really adapting for podman environment (e.g. it was using
images that we don't use here, and would cause pulls, which
will cause flakes). Rewrite test so it references only $IMAGE,
remove some confusing/unnecessary stuff, selectively run
parts of it even when rootless or remote, and add a
test to confirm that copy-from succeeded.
- load test: add error-message test to new load-invalid (#9672).
Basically, make sure the command fails for the right reason.
- play test (kube): use $IMAGE, not alpine; and add pause-image
cleanup to teardown()
- apiv2 mounts test: add a maintainability comment in a tricky
section of code; and tighten up the mount point test.

podman gating tests are hanging in the new Fedora CI setup;
long and tedious investigation suggests that 'socat' processes
are being left unkilled, which then causes BATS to hang when
it (presumably) runs a final 'wait' in its end cleanup.
The two principal changes are to exec socat in a subshell
with fd3 closed, and to pkill its child processes before
killing the process itself. I don't know if both are needed.
The pkill definitely is; the exec may just be superstition.
Since I've wasted more than a day of PTO time on this, I'm
okay with a little superstition. What I do know is that with
these two changes, my reproducer fails to reproduce in over
one hour of trying (normally it fails within 5 minutes).
AND, update: only rawhide (f35) leaves stray socat processes
behind. f33 and ubuntu do not, so 'pkill -P' fails.
I really have no idea what's going on.

Copy is full of perils. Some of them are the nuances when copying
directories. Who would have thought that
* cp dir foo
* cp dir/ foo
* cp dir/. foo
are all supposed to yield the same result when foo does not exist.
`podman cp` now supports all three notations, which required to massage
the front-end code in `cmd/podman` a bit. The tests have been extended
and partially rewritten to test container->host and host->container
copy operations.

Traditionally, the path resolution for containers has been resolved on
the *host*; relative to the container's mount point or relative to
specified bind mounts or volumes.
While this works nicely for non-running containers, it poses a problem
for running ones. In that case, certain kinds of mounts (e.g., tmpfs)
will not resolve correctly. A tmpfs is held in memory and hence cannot
be resolved relatively to the container's mount point. A copy operation
will succeed but the data will not show up inside the container.
To support these kinds of mounts, we need to join the *running*
container's mount namespace (and PID namespace) when copying.
Note that this change implies moving the copy and stat logic into
`libpod` since we need to keep the container locked to avoid race
conditions. The immediate benefit is that all logic is now inside
`libpod`; the code isn't scattered anymore.
Further note that Docker does not support copying to tmpfs mounts.
Tests have been extended to cover *both* path resolutions for running
and created containers. New tests have been added to exercise the
tmpfs-mount case.
For the record: Some tests could be improved by using `start -a` instead
of a start-exec sequence. Unfortunately, `start -a` is flaky in the CI
which forced me to use the more expensive start-exec option.
