The on-failure restart option supports restarting only a given
number of times. To do this, we need one additional field in the
DB to track restart count (which conveniently fills a field in
Inspect we weren't populating), plus some plumbing logic.

This field indicates that a container was explciitly stopped by
an API call, and did not exit naturally. It's used when
implementing restart policy for containers.

Fallback to executing ps(1) in case we hit an unknown psgo descriptor.
This ensures backwards compatibility with docker-top, which was purely
ps(1) driven.
Also support comma-separated descriptors as input.

the podman generate systemd command will generate a systemd unit file
based on the attributes of an existing container and user inputs. the
command outputs the unit file to stdout for the user to copy or
redirect. it is enabled for the remote client as well.
users can set a restart policy as well as define a stop timeout
override for the container.

When running inside Podman, we get an extra `nodev` mount option.
It doesn't seem to be a bug, more an artifact of running in a
somewhat locked-down container. So instead of checking explicitly
for a set of mount options, just verify the ones we set are
present.

Existing code was not working due to a bash gotcha ('exit'
from a pipeline). It also had unnecessary duplication.
New version is safer; also includes unit tests run under localunit.
Existing invocations of req_env_var replaced via:
$ [ edit setup_environment.sh, move one closing quote to its own line ]
$ perl -ni -e 's/(?<=req_env_var )"(\S+)\s+\$\1"/$1/; if (/req_env_var "$/ .. /^\s*"/) { chomp; s/(?<=\S)\s.*//; if (/^\s*"/) { print "\n" } else { unless (/req_env_var/) { s/^\s+//; print " ";} print;} } else { print }' $(ack -l req_env_var)
$ [ hand-massage an incorrect instance of '@' in lib.sh:ircmsg() ]

We merged #2950 with some nits still remaining, as Giuseppe was
going on PTO. This addresses those small requested changes.

As part of this, rework the number of workers used by various
Podman tasks to match original behavior - need an explicit
fallthrough in the switch statement for that block to work as
expected.
Also, trivial change to Podman cleanup to work on initialized
containers - we need to reset to a different state after cleaning
up the OCI runtime.

This ensures that all tmpfs mounts added by the user, even with
the --mount flag, share a few common options (nosuid, noexec,
nodev), and options for tmpfs mounts are properly validated to
ensure they are correct.

As part of this, move bind mount option validity parsing and
modification (adding e.g. rbind on bind mounts that are missing
it), which requires test changes (expected values have changed).

We were unconditionally resetting volume mount options for all
mount points (and by the looks of things, completely dropping
tmpfs mounts), which was causing runc to refuse to run containers
and all the tests to consequently fail.

Several changes made in the interface of pkg/spec make
interacting with it without a runtime difficult to impossible,
so move the existing limited testing from cmd/podman (which
mostly tested pkg/spec) into pkg/spec itself where we can call
individual functions that don't break things.

Unify handling for the --volume, --mount, --volumes-from, --tmpfs
and --init flags into a single file and set of functions. This
will greatly improve readability and maintainability.
Further, properly handle superceding and conflicting mounts. Our
current patchwork has serious issues when mounts conflict, or
when a mount from --volumes-from or an image volume should be
overwritten by a user volume or named volume.
