When we rewrote Podman's pkg/spec, one of the things that was
lost was our use of a set of default environment variables, that
ensure all containers have at least $PATH and $TERM set.
While we're in the process of re-adding it, change it from a
variable to a function, so we can ensure the Join function does
not overwrite it and corrupt the defaults.

The ListContainers API previously had a Pod parameter, which
determined if pod name was returned (but, notably, not Pod ID,
which was returned unconditionally). This was fairly confusing,
so we decided to deprecate/remove the parameter and return it
unconditionally.
To do this without serious performance implications, we need to
avoid expensive JSON decodes of pod configuration in the DB. The
way our Bolt tables are structured, retrieving name given ID is
actually quite cheap, but we did not expose this via the Libpod
API. Add a new GetName API to do this.

Buildah and podman build can create images without a working dir.
FROM fedora
WORKDIR /test
If you build this image with caching twice, the second time the image
will not have a working dir.
Similarly if you execute
podman run --workdir /foobar fedora
It blows up since the workingdir is not created automatically.
Finally there was duplicated code for getting the workingdir
out of an image, that this PR removes.

This matches Docker behavior, and seems to make sense - the CMD
may have been specific to the original entrypoint and probably
does not make sense if it was changed.
While we're in here, greatly simplify the logic for populating
the SpecGen's Command. We create the full command when making the
OCI spec, so the client should not be doing any more than setting
it to the Command the user passed in, and completely ignoring
ENTRYPOINT.

A recent crun change stopped the creation of the container's
working directory if it does not exist. This is arguably correct
for user-specified directories, to protect against typos; it is
definitely not correct for image WORKDIR, where the image author
definitely intended for the directory to be used.
This makes Podman create the working directory and chown it to
container root, if it does not already exist, and only if it was
specified by an image, not the user.

I'm not sure if this is an OS-specific issue, but on CentOS 8, if `path`
doesn't exist, this hangs while waiting to read from this socket, even
though the socket is closed by the `reexec_in_user_namespace`. Switching
to a pipe fixes the problem, and pipes shouldn't be an issue since this is
Linux-specific code.

Commit 2b6dd3fb43 set the killmode of the podman.service to the
systemd default which ultimately lead to the problem that systemd
will kill *all* processes inside the unit's cgroup and hence kill
all containers whenever the service is stopped.
Fix it by setting the type to sdnotify and the killmode to process.
`podman system service` will send the necessary notify messages
when the NOTIFY_SOCKET is set and unset it right after to prevent
the backend and container runtimes from jumping in between and send
messages as well.

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.

Bind-mounting /etc/passwd into the container is problematic
becuase of how system utilities like `useradd` work. They want
to make a copy and then rename to try to prevent breakage; this
is, unfortunately, impossible when the file they want to rename
is a bind mount. The current behavior is fine for read-only
containers, though, because we expect useradd to fail in those
cases.
Instead of bind-mounting, we can edit /etc/passwd in the
container's rootfs. This is kind of gross, because the change
will show up in `podman diff` and similar tools, and will be
included in images made by `podman commit`. However, it's a lot
better than breaking important system tools.

NOTE: the remote tests are not reenabled but the changes are applied.
Future commits depend on some of the changes and having the commit
applied will likely facilitate future backports as well.
podman-remote is in better shape now. Let's see what needs
to be done to reenable remote system tests.
- logs test: skip multilog, it doesn't work remote
- diff test: use -l only when local, not with remote
- many other tests: skip_if_remote, with 'FIXME: pending #xxxx'
where xxxx is a filed issue.
Unrelated: added new helper to skip_if_remote and _if_rootless,
where we check if the source message includes "remote"/"rootless"
and insert it if missing. This is a minor usability enhancement
to make it easier to understand at-a-glance why a skip triggers.

Docker and CNI have very different ideas of what 0.0.0.0 means.
Docker takes it to be 0.0.0.0/0 - that is, bind to every IPv4
address on the host. CNI (and, thus, root Podman) take it to mean
the literal IP 0.0.0.0. Instead, CNI interprets the empty string
("") as "bind to all IPs".
We could ask CNI to change, but given this is established
behavior, that's unlikely. Instead, let's just catch 0.0.0.0 and
turn it into "" when we parse ports.

In local Podman, the frontend interprets the error and exit code
given by the Exec API to determine the appropriate exit code to
set for Podman itself; special cases like a missing executable
receive special exit codes.
Exec for the remote API, however, has to do this inside Libpod
itself, as Libpod will be directly queried (via the Inspect API
for exec sessions) to get the exit code. This was done correctly
when the exec session started properly, but we did not properly
handle cases where the OCI runtime fails before the exec session
can properly start. Making two error returns that would otherwise
not set exit code actually do so should resolve the issue.
