The dangling filter determine whether a volume is dangling - IE,
it has no containers attached using it. Unlike our other filters,
this one is a boolean - must be true or false, not arbitrary
values.

New functionality in hack/man-page-checker: start cross-
referencing the man page 'Synopsis' line against the
output of 'podman foo --help'. This is part 1, flag/option
consistency. Part 2 (arg consistency) is too big and will
have to wait for later.
flag/option consistency means: if 'podman foo --help'
includes the string '[flags]' in the Usage message,
make sure the man page includes '[*options*]' in its
Synopsis line, and vice-versa. This found several
inconsistencies, which I've fixed.
While doing this I realized that Cobra automatically
includes a 'Flags:' subsection in its --help output
for all subcommands that have defined flags. This
is great - it lets us cross-check against the
usage synopsis, and make sure that '[flags]' is
present or absent as needed, without fear of
human screwups. If a flag-less subcommand ever
gets extended with flags, but the developer forgets
to add '[flags]' and remove DisableFlagsInUseLine,
we now have a test that will catch that. (This,
too, caught two instances which I fixed).
I don't actually know if the new man-page-checker
functionality will work in CI: I vaguely recall that
it might run before 'make podman' does; and also
vaguely recall that some steps were taken to remedy
that.

Throw an error if a specified tag does not exist. Also make sure that
the user input is normalized as we already do for `podman tag`.
To prevent regressions, add a set of end-to-end and systemd tests.
Last but not least, update the docs and add bash completions.

When going through the output of `podman inspect` to try and
identify another issue, I noticed that Podman 2.0 was setting
StopSignal to 0 on containers by default. After chasing it
through the command line and SpecGen, I determined that we were
actually not setting a default in Libpod, which is strange
because I swear we used to do that. I re-added the disappeared
default and now all is well again.
Also, while I was looking for the bug in SpecGen, I found a bunch
of TODOs that have already been done. Eliminate the comments for
these.

...plus a few others. And fixes to actual parsing.
If a command's usage message includes '...' in the
argument list, assume it can take unlimited arguments.
Nothing we can check.
For all others, though, the ALL-CAPS part on the
right-hand side of the usage message will define
an upper bound on the number of arguments accepted
by the command. So in our 'podman --help' test,
generate N+1 args and run that command. We expect
a 125 exit status and a suitably helpful error message.
Not all podman commands or subcommands were checking,
so I fixed that. And, fixed some broken usage messages
(all-caps FLAGS, and '[flags]' at the end of 'ARGS').
Add new checks to the help test to prevent those in
the future.
Plus a little refactoring/cleanup where necessary.

Reversion of one part of #6679: my handling of 'realpath'
would not work when $PODMAN is 'podman-remote --url etc'.
Trying to handle that case got unmaintainable; so instead
let's just force 'make {local,remote}system' to invoke
with a full PODMAN path. This breaks down if someone
runs the tests with a manual 'bats' invocation, but I
think I'm the only one who ever does that.
Since podman path will now be very long in the logs,
add code to logformatter to abbreviate it like we do
for the ginkgo logs.
And, one thing that has bugged me for a long time:
in the error logs, show a different prompt ('#' vs '$')
to distinguish root vs rootless. This should make it
much easier to see at-a-glance whether a log file
is root or not. Add tests for it.

Support both `last` and `limit` for in the containers listing endpoint.
We intended to use `limit` which is also mentioned in the docs, but the
implementation ended up using `last` as the http parameter; likely being
caused by the CLI using `--last`. To avoid any regression, we decided
for supporting both and aliasing `last`.

This incorporates code from PR #6591 and #6614 but does not use
event channels to detect container state and rather uses timers
with a defined wait duration before calling t.StopAtEOF() to
ensure the last log entry is output before a container exits.
The polling interval is set to 250 milliseconds based on polling
interval defined in hpcloud/tail here:

This will allow containers that connect to the network namespace be
able to use the container name directly.
For example you can do something like
podman run -ti --name foobar fedora ping foobar
While we can do this with hostname now, this seems more natural.
Also if another container connects on the network to this container it
can do
podman run --network container:foobar fedora ping foobar
And connect to the original container,without having to discover the name.

Allow wildcards in the search term. Note that not all registries
support wildcards and it may only work with v1 registries.
Note that searching implies figuring out if the specified search term
includes a registry. If there's not registry detected, the search term
will be used against all configured "unqualified-serach-registries" in
the registries.conf. The parsing logic considers a registry to be the
substring before the first slash `/`.
With these changes we now not only support wildcards but arbitrary
input; ultimately it's up to the registries to decide whether they
support given input or not.

We initially believed that implementing this required support for
restarting containers after reboot, but this is not the case.
The unless-stopped restart policy acts identically to the always
restart policy except in cases related to reboot (which we do not
support yet), but it does not require that support for us to
implement it.
Changes themselves are quite simple, we need a new restart policy
constant, we need to remove existing checks that block creation
of containers when unless-stopped was used, and we need to update
the manpages.

When the container uses journald logging, we don't want to
automatically use the same driver for its exec sessions. If we do
we will pollute the journal (particularly in the case of
healthchecks) with large amounts of undesired logs. Instead,
force exec sessions logs to file for now; we can add a log-driver
flag later (we'll probably want to add a `podman logs` command
that reads exec session logs at the same time).
As part of this, add support for the new 'none' logs driver in
Conmon. It will be the default log driver for exec sessions, and
can be optionally selected for containers.
Great thanks to Joe Gooch (mrwizard@dok.org) for adding support
to Conmon for a null log driver, and wiring it in here.

Test has been flaking excessively. A quick look shows that
the test itself is broken, making a bad assumption.
'podman logs -f' is guaranteed to exit when a container
terminates. This does not (and should not) mean that the
container has been cleaned up. It is undefined and unsafe
to run 'podman run -n same-name-as-terminated-container'
immediately after 'podman logs' exits.
Solution: instead of 'podman run', do 'podman inspect'.
This, too, is unsafe, but we can expect to see one of
two possible conditions:
1) command succeeds, in which case we require that
container State.Status be "exited"; or
2) command fails, in which case we expect "no such
container" in error output
For full coverage we should add a small delay-check test
to (1) to ensure that the container is cleaned up after
a short amount of time. Leaving that as a TODO because
it's more than my Go skills can handle, and I want to
get this checked in ASAP to get rid of the flake hassle.
