This fixes the problem where even as root we check the netns files from
root. But in order to catch any rootless bugs we must check the rootless
files from $XDG_RUNTIME_DIR/netns.

When running parallel, multiple tests could be trying to start
the registry at once. Make this parallel-safe.
Also, use a safer port range for the registry. Something
outside of /proc/sys/net/ipv4/ip_local_port_range
Sorry, I'm including a FIXME section that I haven't investigated
deeply enough.

For the past two months we've been splitting system tests
into two categories: those that CAN be run in parallel,
and those that CANNOT. Much work has been done to replace
hardcoded names (mycontainer, mypod) with safename().
Hundreds of test runs, in CI and on Ed's laptop, have
proven this approach viable.
make {local,remote}system now runs in two steps: first
the serial ones, then the parallel ones. hack/bats will
now recognize the 'ci:parallel' tag and add --jobs (nprocs).
This requires some tweaking of leak_check, because there
can be umpteen tests running (affecting image/container/pod/etc
state) when any given test completes.
Rules for enabling parallelization in tests:
* use unique container/pod/volume/network names (safename)
* do not run 'podman rm -a' or 'rmi -a'
* never use the -l (--latest) option
* do not run 'podman ps/images' and expect precise output

At the end of all tests always check for leaks. That should make us more
robust against adding tests at the end that would leak stuff otherwise.
TODO: something seems wrong with bats when returning an error in
teardown_suite(), it prints a warning:
bats warning: Executed <NUM+1> instead of expected <NUM> tests
And also the output is formatted weirdly in this case where the podman
args are split over multiple lines.
But the test fails as expected so I don't think it is a problem.

While these are not really slow they still take about 100-250ms if I
time this locally. Given they are run for every test this adds up
quickly. Looking at CI logs I can see the timings for skipped
tests are all in 600ms range. So I think it is safe to assume that these
functions need to get faster.
We have over 670 test cases currently so we talk about over 400s spend
in these functions in CI. This allows for big gains.
Now overall this is a tricky trade of, while all tests should cleanup
after themselves there is no guarantee for that as such errors can be
leaked into other tests making debugging much harder. To work at least a
bit against this teardown checks if the test was successful and only
skips the podman commands bases on that. Without it a single flake could
cause all following tets to fail.
As such this commit does the proper setup once one suite start then only
after a test failed.
In order for this to work at all we have to fix all leaks first, see
previous commits. And then for the future keep a very strong eye on
this during reviews.
Also add a PODMAN_BATS_LEAK_CHECK option
By default test must cleanup themselves and to speed up CI we no longer
do any cleanup in teardown by default. However there is still many cases
where we might have to debug a leak so add a new PODMAN_BATS_LEAK_CHECK
env option that can be set and should cause teardown to fail if the test
did not cleanup properly.

This was added ages ago in commit c65b3599cc, however in the meantime
both podman and conmon can support longer socket paths as they use a
workaround to open the path via /proc/self/fd, see openUnixSocket() in
libpod/oci_conmon_attach_linux.go
Thus this restriction is not needed anymore and we can drop a workaround
in the tests.
Fixes#22272

Our test registry (used for login & local registry tests)
was being run using the standard podman tmpdir, hence the
standard podman database, This was then getting clobbered
in the 330-corrupt-images test, which runs "system reset".
We just didn't know this was happening. Until we added
a registry test after the system reset. Oops.
Solution: new helper function podman_isolation_opts()
sets --root, --runroot, *and --tmpdir*. Refactor all
existing --root/--runroot usages. Document.
Next problem: the "network reload" test in 500-networking.bats
did not (could not) know about our registry port, so the
"iptables -F" command reverted that to DROP, so the subsequent
podman-auth in 700-play timed out.
Solution: add a podman-isolated "network reload" to start_registry().
Final problem, because, really, those weren't enough: a BATS
bug where running with --filter-tags would set IFS=',' in setup_suite
which in turn has catastrophic consequences:
https://github.com/bats-core/bats-core/issues/812
See #20966 for details of the failure and further conversation.

The podman-login tests have accumulated much cruft over the
years, because that's the only place where we run a local
registry, and the process was crufty: we actually start/stopped
the registry as the first & last tests of the file. Meaning,
you couldn't do 'hack/bats 150:just-one-test' because that
would skip the registry start. And just now, a completely
unrelated test has had to be shoved into the login file.
This PR revamps the whole thing, by adding a new registry helper
module that can be used anywhere. And, once the registry is
started, it just stays running until the end of tests. (This
requires BATS 1.7 or greater).
