Followup to #9740. Nice work, but the _confirm_update() helper
was dangerously broken and I just wasn't able to communicate
that. Given the time zone difference, and my weekly time cost
in reviewing, it's easier for me to fix it myself. (The problem
is that the function was a complete NOP, which would lead to
flakes).
Also: got rid of some clutter, restructured a few minor places
for maintainability.

System test: Add tests for podman auto-update

Add some cases for podman auto-update:
1. Test with different value for label io.containers.autoupdate
2. Run podman auto-update as systemd timer

remote: always send resize before the container starts

There is race condition in the remote client attach logic. Because the
resize api call was handled in an extra goroutine the container was
started before the resize call happend. To fix this we have to call
resize in the same goroutine as attach. When the first resize is done
start a goroutine to listen on SIGWINCH in the background and resize
again if the signal is received.

Fix a bug in remote events where only one event would be sent if when
streaming is turned off. The source of the bug was that the handler
attempted to implement the streaming logic and did it wrong. The fix is
rather simple by removing this logic from the handler and let the events
backend handle streaming.

The containers /etc/resolv.conf allways preserved the ipv6 nameserves
from the host even when the container did not supported ipv6. Check
if the cni result contains an ipv6 address or slirp4netns has ipv6
support enabled and only add the ipv6 nameservers when this is the case.
The test needs to have an ipv6 nameserver in the hosts /etc/hosts but we
should never mess with this file on the host. Therefore the test is
skipped when no ipv6 is detected.

selinux-policy-34.9-1.fc34 breaks a behavior we've relied on
since (at least) January 2020:
- Revert "Add permission open to files_read_inherited_tmp_files()
interface"
That's probably the correct thing to do, but it breaks our
existing tests. Solution: add ':Z' where needed.
Tested on Ed's laptop, which has the offending selinux-policy
as of 2021-05-31. Tests pass root and rootless. (I mention
this because tests will obviously pass in CI, which has a
much older selinux-policy).
Also: add a 'podman rmi' for cleanup in one test, to avoid
noise in test logs.

Fix a race in journald driver. Following the logs implies streaming
until the container is dead. Streaming happened in one goroutine,
waiting for the container to exit/die and signaling that event happened
in another goroutine.
The nature of having two goroutines running simultaneously is pretty
much the core of the race condition. When the streaming goroutines
received the signal that the container has exitted, the routine may not
have read and written all of the container's logs.
Fix this race by reading both, the logs and the events, of the container
and stop streaming when the died/exited event has been read. The died
event is guaranteed to be after all logs in the journal which guarantees
not only consistencty but also a deterministic behavior.
Note that the journald log driver now requires the journald event
backend to be set.

Currently if a user specifies a --root flag to override the location of
the container storage, we still enforce the storage-opts from
storage.conf. This causes issues with people trying to intereact with
the additional stores feature, and then forces them to use the obscure
--storage-opt="" option. I belive this should be the default and we
already do this when the user specifies the --storage-driver option.

When attempting to copy files into and out of running containers
within the host pidnamespace, the code was attempting to join the
host pidns again, and getting an error. This was causing the podman
cp command to fail. Since we are already in the host pid namespace,
we should not be attempting to join. This PR adds a check to see if
the container is in NOT host pid namespace, and only then attempts to
join.

The initial version of libimage changed the order of layers which has
now been restored to remain backwards compatible.
Further changes:
* Fix a bug in the journald logging which requires to strip trailing
new lines from the message. The system tests did not pass due to
empty new lines. Triggered by changing the default logger to
journald in containers/common.
* Fix another bug in the journald logging which embedded the container
ID inside the message rather than the specifid field. That surfaced
in a preceeding whitespace of each log line which broke the system
tests.
* Alter the system tests to make sure that the k8s-file and the
journald logging drivers are executed.
* A number of e2e tests have been changed to force the k8s-file driver
to make them pass when running inside a root container.
* Increase the timeout in a kill test which seems to take longer now.
Reasons are unknown. Tests passed earlier and no signal-related
changes happend. It may be CI VM flake since some system tests but
other flaked.

When a container is automatically restarted due its restart policy and
the container used the slirp4netns netmode, the slirp4netns process
died. This caused the container to lose network connectivity.
To fix this we have to start a new slirp4netns process.

The with --new generated systemd unit loses the environment variables
when the create command only contains the key without the value. Since
podman tries to lookup those values from the environment the unit can
fail.
This commits ensures that we will add the environment variables to the
unit file when this is the case. The container environment variables are
looked up in the container spec.

Reason: to catch errors before they surface in RHEL.
One of the Ubuntus is specially crafted to run with cgroups v1
and runc. Although this isn't quite the same as RHEL, it's as
close as we can come in our CI environment, and I suspect it
would have caught #10234 (a regression).
Sorry, team.
Also: play kube limits test: skip on all rootless, not just
rootless+fedora. There was a complicated and unnecessary
check in there for Fedora.
Also: workaround for bug #10248, a spurious error message on
the first invocation of rootless podman on Ubuntu.Old

Migrate the Podman code base over to `common/libimage` which replaces
`libpod/image` and a lot of glue code entirely.
Note that I tried to leave bread crumbs for changed tests.
Miscellaneous changes:
* Some errors yield different messages which required to alter some
tests.
* I fixed some pre-existing issues in the code. Others were marked as
`//TODO`s to prevent the PR from exploding.
* The `NamesHistory` of an image is returned as is from the storage.
Previously, we did some filtering which I think is undesirable.
Instead we should return the data as stored in the storage.
* Touched handlers use the ABI interfaces where possible.
* Local image resolution: previously Podman would match "foo" on
"myfoo". This behaviour has been changed and Podman will now
only match on repository boundaries such that "foo" would match
"my/foo" but not "myfoo". I consider the old behaviour to be a
bug, at the very least an exotic corner case.
* Futhermore, "foo:none" does *not* resolve to a local image "foo"
without tag anymore. It's a hill I am (almost) willing to die on.
* `image prune` prints the IDs of pruned images. Previously, in some
cases, the names were printed instead. The API clearly states ID,
so we should stick to it.
* Compat endpoint image removal with _force_ deletes the entire not
only the specified tag.

System tests: honor $OCI_RUNTIME (for CI)

Some CI systems set $OCI_RUNTIME as a way to override the
default crun. Integration (e2e) tests honor this, but system
tests were not aware of the convention; this means we haven't
been testing system tests with runc, which means RHEL gating
tests are now failing.
The proper solution would be to edit containers.conf on CI
systems. Sorry, that would involve too much CI-VM work.
Instead, this PR detects $OCI_RUNTIME and creates a dummy
containers.conf file using that runtime.
Add: various skips for tests that don't work with runc.
Refactor: add a helper function so we don't need to do
the complicated 'podman info blah blah .OCIRuntime.blah'
thing in many places.
BUG: we leave a tmp file behind on exit.
