The intention of --read-only-tmpfs=fals when in --read-only mode was to
not allow any processes inside of the container to write content
anywhere, unless the caller also specified a volume or a tmpfs. Having
/dev and /dev/shm writable breaks this assumption.

HPC Community asked for this support specifically for using GPUs
within containers. Nvidia requires the correct shared library to
to be present in the directory that matches the device mounted
into the container. These libraries have random suffixes based
on versions of the installed libraries on the host.
podman run --mount type=glob:src=/usr/lib64/nvidia\*:ro=true. This helps
quadlets be more portable for this use case.

Use "--wait" flag in "systemd start" for a one-shot container.
Should fix a CI failure I've been seeing sporadically, in which
the --==VALUE==-- string is not seen in journal.

If a user puts a quadlet file in his homedirectory with
the same name as one in /etc/containers/systemd/user or
/etc/containers/systemd/user/$UID, then only use the one in
homedir and ignore the others.

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.

Quick followup to #19348:
- refactor into table form, for legibility
- add tests for 'podman kube play' and 'podman run'
- slightly cleaner message on failure

Add a new "healthy" sdnotify policy that instructs Podman to send the
READY message once the container has turned healthy.

**podman compose** is a thin wrapper around an external compose provider
such as docker-compose or podman-compose. This means that `podman
compose` is executing another tool that implements the compose
functionality but sets up the environment in a way to let the compose
provider communicate transparently with the local Podman socket. The
specified options as well the command and argument are passed directly
to the compose provider.
The default compose providers are `docker-compose` and `podman-compose`.
If installed, `docker-compose` takes precedence since it is the original
implementation of the Compose specification and is widely used on the
supported platforms (i.e., Linux, Mac OS, Windows).
If you want to change the default behavior or have a custom installation
path for your provider of choice, please change the `compose_provider`
field in `containers.conf(5)`. You may also set the
`PODMAN_COMPOSE_PROVIDER` environment variable.

`podman system service` + TCP is not a configuration we should be
recommending. There was already language about this in the
manpages, but it was not sufficient in explaining how bad of an
idea this is. Expand the manpage warnings, add a dedicated
heading so people notice, and add a warning every time the
service starts with a TCP URL that directs people to the manpage
to see that explanation.

Some quadlet tests are failing on RHEL8: test code was
using journalctl to check output from containers. This
fails on RHEL8, where default log driver is k8s-file.
Solution: use 'podman logs' instead. To do so, we need to
keep the containers alive (otherwise, quadlet seems to
delete them on exit). Do so by running 'top -b' (batch);
the currently-used 'top' was failing because not-a-tty.

quadlet volume-path system test was making invalid assumptions
about $TMPDIR, causing test to fail when TMPDIR=/var/tmp or /dev/shm
Much more complicated than it should be, because we need to
find out the systemd value of %T.

Fixes a bug where `podman volume ls` with multiple `label` filters would
return volumes that matched *any* of the filters, not *all* of them.
Adapts generating volume filter functions to be more in
line with how it is done for containers and pods.

Adds any required "wiring" to ensure the reserved annotations are supported by
`podman kube play`.
Addtionally fixes a bug where, when inspected, containers created using
the `--publish-all` flag had a field `.HostConfig.PublishAllPorts` whose
value was only evaluated as `false`.

- the "podman {run,exec} /etc" test: runc now spits out
"is a directory" instead of "permission denied". And,
on exec, exits 255 instead of 126. Deal with it.
