Podman is attempting to split the headers returned by the ps
command into a list of headers. Problem is that some headers
are multi-word, and headers are not guaranteed to be split via
a tab. This PR splits the headers bases on white space, and for
the select group of CAPS headers which are multi-word, combines
them back together.

When using the docker REST API to wait for a container to be removed,
for example, WaitContainerDocker uses a one microsecond interval between
poll requests. This ends up being effectively a busy-wait, with the
podman system service spinning at > 100% CPU time.
The equivalent Podman method uses a 250ms default. Use that for the
docker variant, too.
I'm going to optimistically assert [NO NEW TESTS NEEDED] - given there's
no functional change here, and a test will require some form of mocking
or strac'ing the binary for evidence that it's polling less frequently,
unless someone who is familiar with podman can briefly explain what kind
of test would be appropriate here.

Allow users to customize the network_interface option is the network
config. For bridge this allows users to change the bridge name and for
maclvan it will be the same as `--opt parent=...`.
However the main reason for this option is to allow netavark plugins to
make use of it. I demoed the host-device plugin which makes use of this
as an example. While we could let users set them via --opt it is more
natural to just use the field which is designed for that purpose.

Currently --tmpdir changes the location of the pause.pid file. this
causes issues because the c code in pkg/rootless does not know about
that. I tried to fix this[1] by fixing the c code to not use the
shortcut. While this fix worked it will result in many pause processes
leaking in the integrration tests.
Commit ab88632 added this behavior but following the disccusion it was
never the intention that we end up having more than one pause process.
The issues that was trying to fix was caused by somthing else AFAICT,
the main problem seems to be that the pause.pid file parent directory
may not be created when we try to create the pid file so it failed with
ENOENT. This patch fixes it by creating this directory always and revert
the change to no longer depend on the tmpdir value.
With this commit we now always use XDG_RUNTIME_DIR/libpod/tmp/pause.pid
for all podman processes. This allows the c shortcut to work reliably
and should therefore improve perfomance over my other approach.
A system test is added to ensure we see the right behavior and that
podman system migrate actually stops the pause process. Thanks to Ed
Santiago for the improved test to make it work for both `catatonit` and
`podman pause`.
This should fix the issues with namespace missmatches that we can see in
CI as flakes.

add a function to securely mount a subpath inside a volume. We cannot
trust that the subpath is safe since it is beneath a volume that could
be controlled by a separate container. To avoid TOCTOU races between
when we check the subpath and when the OCI runtime mounts it, we open
the subpath, validate it, bind mount to a temporary directory and use
it instead of the original path.
