add a new option --preserve-fd that allows to specify a list of FDs to
pass down to the container.
It is similar to --preserve-fds but it allows to specify a list of FDs
instead of the maximum FD number to preserve.
--preserve-fd and --preserve-fds are mutually exclusive.
It requires crun since runc would complain if any fd below
--preserve-fds is not preserved.

Some system tests run deep loops:
for x in a b c; do
for y in d e f; do
.... check condition $x + $y
Normally, if one of these fails, game over. This can be frustrating
to a developer looking for failure patterns.
Here we introduce a new defer-assertion-failure function, meant
to be called before loops like these. Everything is the same,
except that tests will continue running even after failure.
When test finishes, or if test runs immediate-assertion-failure,
a new message indicates that multiple tests failed:
FAIL: X test assertions failed. Search for 'FAIL': above this line.

commit 7ade972102 introduced the change
that caused an issue in crun since it forces the root user session
instead of the system one when DBUS_SESSION_BUS_ADDRESS is set.
I am addressing it in crun, but for the time being, let's also not
pass the variable down to conmon since the assumption is that when
running as root the containers must be created on the system bus.

Pass the _entire_ environment to conmon instead of selectively enabling
only specific variables. The main reasoning is to make sure that conmon
and the podman-cleanup callback process operate in the exact same
environment than the initial podman process. Some configuration files
may be passed via environment variables. Podman not passing those down
to conmon has led to subtle and hard to debug issues in the past, so
passing all down will avoid such kinds of issues in the future.

The processing and setting of the static and volume directories was
scattered across the code base (including c/common) leading to subtle
errors that surfaced in #19938.
There were multiple issues that I try to summarize below:
- c/common loaded the graphroot from c/storage to set the defaults for
static and volume dir. That ignored Podman's --root flag and
surfaced in #19938 and other bugs. c/common does not set the
defaults anymore which gives Podman the ability to detect when the
user/admin configured a custom directory (not empty value).
- When parsing the CLI, Podman (ab)uses containers.conf structures to
set the defaults but also to override them in case the user specified
a flag. The --root flag overrode the static dir which is wrong and
broke a couple of use cases. Now there is a dedicated field for in
the "PodmanConfig" which also includes a containers.conf struct.
- The defaults for static and volume dir and now being set correctly
and adhere to --root.
- The CONTAINERS_CONF_OVERRIDE env variable has not been passed to the
cleanup process. I believe that _all_ env variables should be passed
to conmon to avoid such subtle bugs.
Overall I find that the code and logic is scattered and hard to
understand and follow. I refrained from larger refactorings as I really
just want to get #19938 fixed and then go back to other priorities.
https://github.com/containers/common/pull/1659 broke three pkg/machine
tests. Those have been commented out until getting fixed.

With few exceptions, commands that exit 0 should not emit any
messages with level=warning or =error. Let's start enforcing
that in run_podman.
Allow one-off exceptions, typically when we're testing an
actual warning condition (usual case: "podman stop" where it
times out to SIGKILL). Exceptions are specified via:
run_podman 0+w subcommand...
^^^---- or, rarely, 0+e
"0" stands for "expect exit status 0", which is the default
so it's implicit anyway. The +w / +e (or even +we) is the
new part. I have added it to tests where necessary.
And, because life is what it is, add two global exceptions:
- Debian. Because runc has too many flakes.
- kube. Ditto. Kube commands emit lots of nasty error
messages (yes, level=error) that don't seem to affect
results.

BATS 1.8.0 introduces tags: metadata that can be applied to
a single test or one entire file, then used for filtering
in a test run.
Issue #19299 introduces the possibility of using OpenQA
for podman reverse dependency testing: continuous CI on
all packages that can affect podman, so we don't go two
months with no bodhi builds then get caught by surprise
when systemd or kernel or crun change in ways that break us.
This PR introduces one bats tag, "distro-integration".
The intention is for OpenQA (or other) tests to install
the podman-tests package and run:
bats --filter-tags distro-integration /usr/share/podman/test/system
Goal is to keep the test list short and sweet: we do not
need to test command-line option parsing. We *DO* need to
test interactions with systemd, kernel, nethack, and other
critical components.

The current way of bind mounting the host timezone file has problems.
Because /etc/localtime in the image may exist and is a symlink under
/usr/share/zoneinfo it will overwrite the targetfile. That confuses
timezone parses especially java where this approach does not work at
all. So we end up with an link which does not reflect the actual truth.
The better way is to just change the symlink in the image like it is
done on the host. However because not all images ship tzdata we cannot
rely on that either. So now we do both, when tzdata is installed then
use the symlink and if not we keep the current way of copying the host
timezone file in the container to /etc/localtime.
Also note that we need to rebuild the systemd image to include tzdata in
order to test this as our images do not contain the tzdata by default.

Make sure to look for the container's exit code when it's in stopped
state. With `--restart=always`, the container seems to stay in the
stopped state which led the wait logic to loop until the 20 seconds
timeout for the cleanup process to have finished kicks in.
Also defensively make sure to loop when the container is in stopped
state but no exit code has been written yet.
Add a regression test to make sure Podman doesn't wait more than 20
seconds. Even on a CI machine under high load I expect it to take much
much much less than that, so I do not expect this test to flake in the
future.

There are days when I really, really, really hate GNU. Remember
when someone decided that 'head -1' would no longer work, and
that it was OK to break an infinite number of legacy production
scripts? Someone now decided that egrep/fgrep are deprecated,
and our CI logs (especially pr-should-include-tests) are now
filled with hundreds of warning lines, making it difficult
to find actual errors.
I expect that those warnings will be removed quickly after
furious community backlash, just like the 'head -1' fiasco
was quietly reverted, but ITM the warnings are annoying
so I capitulate.

Having a container spin-wait on a /stop file, then exit, is
unsafe: 'podman exec $ctr touch /stop' can get sucked into
container cleanup before the exec terminates, resulting in
the podman-exec failing and hence the test failing.
Most existing instances of this pattern are unnecessary.
Replace those with just 'podman rm -f'.
When necessary, use a variety of safer alternatives.

...not CONTAINERS_CONF. At least for most tests.
Nearly every system test currently using CONTAINERS_CONF=tmpfile
should be using CONTAINERS_CONF_OVERRIDE.
Simple reason: runtime (crun/runc), database_backend (bolt/sqlite),
logger, and other important settings from /etc/c.conf are not
usually written into the tmpfile. Those tests, therefore, are
not running podman as configured on the system.
