The read deadline may yield the READY message to be lost in space.
Instead, use a more Go-idiomatic alternative by using two goroutines;
one reading from the connection, the other watching the container.
[NO NEW TESTS NEEDED] since existing tests are exercising this
functionality already.

Followup to #15616, which is not usable as it is (way, way, way
too much noise) but actually found a few real nits that should
be fixed.

Followup to #15621, which (correctly) removed parentheses from
md files. Turns out, a hidden part of our readthedocs process
depended on those parentheses. Update that step so it handles
the new, correct, <space><section-number> format.
Also update local-testing documentation in README, and clean it
up a little.

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.

This reverts commit c20abf12c7. 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.

Alias
podman --context -> podman --connection
podman context use -> podman system connection default
podman context rm -> podman system connection rm
podman context create -> podman system connection add
podman context ls ->podman system connection ls
podman context inspect ->podman system connection ls --json (For
specified connections)
Podman context is a hidden command, but can be used for existing scripts
that assume Docker under the covers.

--no-reset and --no-stream, in podman-stats and pod-stats.
Very minor tweak to --no-stream to account for pods.

Drop the ExecStop step to simplify the generated units a bit.
The extra ExecStopPost step was added by commit e5c3432944. 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.

This makes setting EffectiveCaps and BoundingCaps conditional on whether
the capabilites field in the spec is non-nil. This allows 'podman inspect'
to work on FreeBSD.

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

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.

There's little practical reason to execute unit-level testing on
multiple platforms, since there's so little platform interaction.
Remove the unit-test runs on Ubuntu, only execute on root-full and
root-less Fedora.

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.
