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.

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.

Play kube was passing the pod, but CreateConfig was not. Unify it
so they both do, so we can remove some unnecessary duplicate
lookup code.

The goal here is to keep only the configuration directly used to
build the container in CreateConfig, and scrub temporary state
and helpers that we need to generate. We'll keep those internally
in MakeContainerConfig.

Right now, there are two major API calls necessary to turn a
filled-in CreateConfig into the options and OCI spec necessary to
make a libpod Container. I'm intending on refactoring both of
these extensively to unify a few things, so make a common
frontend to both that will prevent API changes from leaking out
of the package.

The --read-only-tmpfs option caused podman to mount tmpfs on /run, /tmp, /var/tmp
if the container is running int read-only mode.
The default is true, so you would need to execute a command like
--read-only --read-only-tmpfs=false to turn off this behaviour.

Ensure when using remote attach --no-stdin a mock device is used to
prevent stdin and not nil. This fixes issue #3009.
When starting a container with the remote client, if the container is
already running and the user asks to attach, we should just attach.
This fixes issue #3011

add the ability for podman to read and write events to journald instead
of just a logfile. This can be controlled in libpod.conf with the

we were previously closing as many FDs as they were open when we first
started Podman in the range (3-MAX-FD). This would cause issues if
there were empty intervals, as these FDs are later on used by the
Golang runtime. Store exactly what FDs were first open in a fd_set,
so that we can close exactly the FDs that were open at startup.

podman system prune would leave pods be, and not prune them if they were stopped.
Fix this by adding a `podman pod prune` command that prunes stopped pods similarly to containers.
