Podman has no concept of a "restarting" container - such a
container is just transitioning from running to stopped and
then back to running through our ordinary state machine.
As such, filtering "restarting" containers doesn't work and does
nothing.
Also, make "stopped" containers show as exited - this is a
momentary state we transition to before proper exited.

Currently in podman if a user specifies a command that does not exist
the tool shows the help information. This patch changes it to show
information like:
$ ./bin/podman foobar
Error: unrecognized command 'podman foobar'
Try 'podman --help' for more information.
$ ./bin/podman volume foobar
Error: unrecognized command `podman volume foobar`
Try 'podman volume --help' for more information.
$ ./bin/podman container foobar
Error: unrecognized command `podman container foobar`
Try 'podman container --help' for more information.

...caught by hack/podman-commands.sh script. Which had a little
buglet, which I fixed: add a special case for 'help', which
neither has nor needs a man page.
I believe the podman-commands.sh script is ready to be run in CI,

- document a recommended convention for fail-fast tests
- document the requirement for jq. (And, add a fail-fast
test for its presence; remove the duplicated checks
in subtests)
- add further sanity checks to 'help' test. Add missing
documentation. Remove a no-longer-needed workaround for
usage-message bug fixed in #2486
- add a documented TEMPLATE
- and, since we're at 1.1, enable 'Remote API' check in
version test
- better diagnostics in setup/teardown; add vim filetype hint;
better formatting of actual-vs-expect errors
- new pod-top, logs, build tests
- improve error messages
- add $IMAGE alias for ridiculous $PODMAN_TEST_IMAGE_FQN
- final cleanup, in prep for merge

Initial attempt at writing a framework for podman system tests.
The idea is to define a useful set of primitives that will
make it easy to write actual tests and to interpret results
of failing ones.
This is a proof-of-concept right now; only a small number of
tests, by no means comprehensive. I am requesting review in
order to find showstopper problems: reasons why this approach
cannot work. Should there be none, we can work toward running
these as gating tests for Fedora and RHEL8.

when we are creating a container that depends on another one, be sure
we also join its mount namespace in addition to the user namespace.

it is not enough to join the user namespace where the container is
running. We also need to join the mount namespace so that we can
correctly look-up inside of the container rootfs. This is necessary
to lookup the mounted /etc/passwd file when --user is specified.

In the previous version I forgot to add the fds to preserve into
AdditionalFiles. It doesn't make a difference as the files were still
preserved, but this seems to be the correct way of making it
explicit.

Add explicit [flags] to podman healthcheck run Use message.
Reason: Cobra checks for the string '[flags]' in the Use text.
If absent, and command has options, Cobra appends it. This
is misleading to humans, because the --help output looks like:
podman healthcheck run CONTAINER [flags]
...when of course that won't work.

When looking up a container or pod by from user input, we handle
collisions between names and IDs differently than Docker at
present.
In Docker, when there is a container with an ID starting with
"c1" and a container named "c1", commands on "c1" will always act
on the container named "c1". For the same scenario in podman, we
throw an error about name collision.
Change Podman to follow Docker, by returning the named container
or pod instead of erroring.
This should also have a positive effect on performance in the
lookup-by-full-name case, which no longer needs to fully traverse
the list of all pods or containers.

Before, a pod create would fail if it was set to share no namespaces, but had an infra container. While inefficient (you add a container for no reason), it shouldn't be a fatal failure. Fix this by only failing if the pod was set to share namespaces, but had no infra container, and writing a warning if vice versa.

We're going to feed this into Go's BCP 47 language parser. Language
tags have the form [1]:
language
["-" script]
["-" region]
*("-" variant)
*("-" extension)
["-" privateuse]
and locales have the form [2]:
[language[_territory][.codeset][@modifier]]
The modifier is useful for collation, but Go's language-based API
[3] does not provide a way for us to supply it. This code converts
our locale to a BCP 47 language by stripping the dot and later and
replacing the first underscore, if any, with a hyphen. This will
avoid errors like [4]:
WARN[0000] failed to parse language "en_US.UTF-8": language: tag is not well-formed
when feeding language.Parse(...).

Before, any container with a netNS dependency simply used its dependency container's hosts file, and didn't abide its configuration (mainly --add-host). Fix this by always appending to the dependency container's hosts file, creating one if necessary.
