Use safename for containers, volumes, images.
Build a temporary scratch image for podman image mount, so
we can safely mount/umount it (instead of $IMAGE) without
risk of other parallel tests umounting it.
Fixed some oopsies ("$vol1" is empty string, so, NOP test)
And... an experiment. I'm leaving in my 'ci:parallel' tags
and notes, so I don't have to carry them in #23275. This
is harmless, basically just noisy comments. The drawback
is, if for some reason #23275 does not pan out, I'll have
to go back and remove those tags. Right now I'm feeling
pretty comfortable about this parallelization approach tho.

Use safename instead of hardcoded "test"
Start registry once, in setup_file(), instead of requiring
individual tests to do so.
Add explicit --authfile arg to a bunch of places that now need it
Minor cleanup and improvements in test descriptions. I may have
gotten a little carried away here, but if this test ever fails
these additions will make someone's life much easier.

Strictly speaking we don't need the path yet, but it existing
prevents a lot of strangeness in our path-checking logic to
validate the current Podman configuration, as it was the only
path that might not exist this early in init.

BATS teardown logs are unreadable, making it almost impossible
to see tiny "Leaked this-or-that" messages.
Solution: new _run_podman_quiet() helper, replaces run_podman
in a small number of cases within teardown. Clunky, and
duplicative, sorry.
New helper for leak_check, basically spits out warnings (and
bumps error count) if it sees any output whatsoever from
individual "podman XXX ls" commands.

We bind ports to ensure there are no conflicts and we leak them into
conmon to keep them open. However we bound the ports after the network
was set up so it was possible for a second network setup to overwrite
the firewall configs of a previous container as it failed only later
when binding the port. As such we must ensure we bind before the network
is set up.
This is not so simple because we still have to take care of
PostConfigureNetNS bool in which case the network set up happens after
we launch conmon. Thus we end up with two different conditions.
Also it is possible that we "leak" the ports that are set on the
container until the garbage collector will close them. This is not
perfect but the alternative is adding special error handling on each
function exit after prepare until we start conmon which is a lot of work
to do correctly.

These test steps check the automount feature with multi images for
following item:
1. multi images can be auotmounted with yaml file.
2. if there are same path exist in the images, the last one
should trumps.
3. the volume is mounted readonly in the container.
4. the volumes are only mounted in the specific container, but
not the whole pods.

The test assumes that if more than 1 ip on the host we should be able to
set host.containers.internal. This however is not how the logic works in
the code. What it actually does is to check all ips in the
rootless-netns and then it knows that it cannot use any of these ips.
This includes any podman bridge ips.
You can reproduce the error when you have only one ipv4 on the host then
run a container as root in the background and run the test:
hack/bats --rootless 505:host.containers.internal
So the failure here was that there was already a podman container
running as root on the default bridge thus the test saw 2 ips but then
the rootless run also uses the same subnet for its bridge and the code
knew that ip would not work either. I could have made another special
condition in test but the better way to work around it is to create a
new network. A new network will make sure there are no conflicting
subnets assigned so the test will pass.

Using the scanner is just unnecessary complicated an buggy as it will
not read the final line with a newline. There is also the problem that
it happens in a separate goroutine so it could loose output if we read
the array before the scanner was done.
The API accepts a Writer so we can just directly use a bytes.Buffer
which captures all output in memory without the need of another
goroutine.
This also means that now we always include the final newline in the
output. I checked with docker and they do the same so this is good.

When the file is empty it is possible our code panics as bar.ProxyReader
returns nil when the bar is finished which is the case for 0 size as it
doesn't have to read anything from there. However as this happens on
different goroutines it is race and most of the time still works.
To fix this simply skip the progress bar setup for empty files.
While at it fix the deprecated argument in the tests.

The end goal is making this test file parallel-safe, by:
1) Having all tests use unique names for all objects; and
2) Not doing "rm -a" or "expect ps to be empty".
This commit is not enough to make tests parallel-safe. The
rest of the changes are not relevant for now. This set of
changes is _necessary_ for parallelizing, and is _meaningful_
(good practice) for current linear-testing podman without
introducing any unnecessary cruft.

Make safename() invocations consistent within the same
test. This puts the onus on the caller to add a unique
element when calling multiple times, e.g. "ctr1-$(safename)".
This is not too much of a burden. Major benefit is making
it easy for a reader to associate containers, pods, volumes,
images within a given test.
And, use dashes, not underscores. "podman generate kube"
removes underscores, making it very difficult to do
things like "podman inspect $podname" (because we need
to generate "$podname_with_underscores_removed")

Remnant from the very early days of this test file. There's
a boilerplate $testYaml string used in many tests; each
use requires three clunky lines of prep. Most of those
were not needed; we can (and now do) use _write_test_yaml()
instead.
There are still two instances that could not be fixed in
this commit. I will do those next. This commit is kept

Many system tests use hardcoded names for containers, images,
and everything. This has worked because system tests run
serially. It will not work if we ever run in parallel.
Create a new safename() helper, and use it as follows:
myctr=c_$(safename)
myvol1=v1_$(safename)
...
Find current instances of hardcoded names, and replace
with safe ones.
Whether or not we ever end up parallelizing system tests,
this is simply good practice.
There are far too many instances to fix in one (reviewable) PR.

This commit gets tests working under the new local-registry system:
* amend a few image names, mostly just sticking to a consistent
list of those images in our registry cache. Mostly minor
tag updates.
* trickier: pull_test: change some error messages, and remove
a test that's now a NOP. Basically, with a local (unprotected)
registry we always get "404 manifest unknown"; with a real
registry we'll get "403 I can't tell you".
* trickiest: seccomp_test: build our own images at run time,
with our desired labels. Until now we've been pulling
prebuilt images, but those will not copy to the local
cache registry. Something about v1? Anyhow, I gave up
trying to cache them, and the workaround is straightforward.
Also took the liberty of strengthening a few error-message checks

e2e tests, however, ignore storage.conf. They require everything

The code currently tried to avoid joining the userns from conmon
directly and rather joined to only read the pid file and then send this
back to use so we could join the userns. From the comment this was done
because we could not read the pid file. However this is no longer true
as of commit 49eb5af301 and file is no always owned by the real user.
This means we can just remove this special logic and join the namespace
directly there. A test has been added to check the rejoin logic with a
custom uidmapping.
