Cirrus: Move gitlab test to cirrus-cron "main"

There's little need to execute this test for (nearly) every PR.
Further, since it always executes the *latest* upstream tests, there's
no need to run it on any branch other than `main`. Arrange for it to
only execute for the `main` cirrus-cron trigger.

There's little practical reason to execute unit-level testing on

Remove the unit-test runs on Ubuntu, only execute on root-full and

Only between podman-build, create, and run. podman-pod-create
is too different.
As usual I went with the podman-run version. This means
keeping the word "flag" (which should be "option"), for
ease of review. I will fix in my in-progress cleanup PR.
For podman-build, I removed "during the build" and changed
it to a note for that man page only.

Also update local-testing documentation in README, and clean it

...gathered up from the last few months of almost-daily runs.
The principal difference is, ditching the git-am approach in
favor of git-cherry-pick. It's so much nicer! I keep forgetting
how clumsy git-am is. With the new approach, saved checkpoints
are kept as git branches, not in an easy-to-lose text file.
And, conflict resolution is MUCH EASIER. (Conflict resolution
is necessary when, e.g., the treadmill PR includes fixes for
some new vendoring that buildah has done but not podman, then
podman vendors in that same module but fixes broken tests in
a different way than I did).
Also a lot of smaller fixes for bugs reported by @Luap99.
Thank you for testing and for letting me know of problems!
Cursory review is OK: this will not break anything in the repo,
and I've been testing/finetuning these changes heavily over
the past month or two.

This reverts commit c20abf12c714f359c7bbb291c444530f70cb1185. In the
absence of `ExecStop` step, systemd will send the stop/kill signals to
the main PID while I asummed that systemd would jump directly to an
ExecStopPost step instead.
Hence revert the commit to let Podman take care of stopping rather than
systemd.

Originally, during pod removal, we locked every container in the
pod at once, did a number of validity checks to ensure everything
was safe, and then removed all the containers in the pod.
A deadlock was recently discovered with this approach. In brief,
we cannot lock the entire pod (or much more than a single
container at a time) without causing a deadlock. As such, we
converted to an approach where we just looped over each container
in the pod, removing them individually. Unfortunately, this
removed a lot of the validity checking of the earlier approach,
allowing for a lot of unintended bad things. Infra containers
could be removed while containers in the pod still depended on
them, for example.
There's no easy way to do validity checks while in a simple loop,
so I implemented a version of our graph-traversal logic that
currently handles pod start. This version acts in the reverse
order of startup: startup starts from containers which depend on
nothing and moves outwards, while removal acts on containers which
have nothing depend on them and moves inwards. By doing graph
traversal, we can guarantee that nothing is removed while
something that depends on it still exists - so the infra
container should be the last thing in a pod that is removed, for
example.
In the (unlikely) case that a graph of the pod's containers
cannot be built (most likely impossible without database editing)
the old method of pod removal has been retained to ensure that
even misbehaving pods can be forcibly evicted from the state.
I'm fairly confident that this resolves the problem, but there
are a lot of assumptions around dependency structure built into
the original pod removal code and I am not 100% sure I have
captured all of them.

Drop the ExecStop step to simplify the generated units a bit.
The extra ExecStopPost step was added by commit e5c343294424. If the
main PID (i.e., conmon) is killed, systemd will not execute ExecStop
(since the main PID is already down) but only execute the *Post steps.
Credits to the late Ulrich Obergfell for tracking this issue down; he is
missed.
The ExecStop step can safely be dropped since the Post step will take of
stopping (and removing) in any case.

Mostly went with the podman-run version. For ease of review, I
kept the "you" word -- I will fix that in my in-progress

This affects lots of files, each of which had slightly different
wording, but this actually isn't as bad as it looks. The diffs
were minor, and I'm pretty sure the new refactored text applies
equally well to all the man pages.

Followup to #15673 (--format with newlines). I cobbled up a test
for it, but I was sloppy, so the test had issues that I kept
having to band-aid. This is a cleaner way to handle podman-machine.
...and, another unexpected surprise with podman stats. It
fails under rootless cgroupsv1. We can't sweep it under the
rug via skip_if_ubuntu because tests will then fail on RHEL8.
So, add a similar mechanism for testing podman stats.
...plus a non-surprise, the 'search' test flakes. Try minimizing
that by searching only $IMAGE. If quay.io is down, other tests
will certainly fail.

Ensure that a broken OCI spec does not break inspect

The process of saving the OCI spec is not particularly
reboot-safe. Normally, this doesn't matter, because we recreate
the spec every time a container starts, but if one was to reboot
(or SIGKILL, or otherwise fatally interrupt) Podman in the middle
of writing the spec to disk, we can end up with a malformed spec
that sticks around until the container is next started. Some
Podman commands want to read the latest version of the spec off
disk (to get information only populated after a container is
started), and will break in the case that a partially populated
spec is present. Swap to just ignoring these errors (with a
logged warning, to let folks know something went wrong) so we
don't break important commands like `podman inspect` in these
cases.
