Jhon Honce c0c44ae8a3 Fix handler and systemd activation errors
On panic from handler: log warning and stack trace, report
InternalServerError to client

When using `podman system service` make determining the listening endpoint deterministic.

  // When determining _*THE*_ listening endpoint --
  // 1) User input wins always
  // 2) systemd socket activation
  // 3) rootless honors XDG_RUNTIME_DIR
  // 4) if varlink -- adapter.DefaultVarlinkAddress
  // 5) lastly adapter.DefaultAPIAddress

Fix SELinux labels of volumes
If we attempt to label a volume and the file system
does not support labeling, then just warn.  SELinux
may or may not work, on the volume.

There is no way to setup a private label on a newly
created volume without using the container mountlabel.

If we don't have a mount label at the time of creation of
the volume, the only option we have is to create a shared
label.

Valentin Rothberg 816e50ba02 podman-generate-systemd --new
Add a --new flag to podman-generate-systemd to create a new container
via podman-run instead of starting an existing container.

Creating a new container presents the challenge to find a reverse
mapping from a container to the CLI flags it can be created with.  We
are doing this via `(Container).Config.CreateCommand` field, which
includes a copy of the process' command from procFS at creating time.
This field may not be useful when the container was not created via the
Podman CLI (e.g., via a Python script).  Hence, we do not guarantee the
correctness of the generated files.

Correctly export the root file-system changes
When doing a checkpoint with --export the root file-system diff was not
working as expected. Instead of getting the changes from the running
container to the highest storage layer it got the changes from the
highest layer to that parent's layer. For a one layer container this
could mean that the complete root file-system is part of the checkpoint.

With this commit this changes to use the same functionality as 'podman
diff'. This actually enables to correctly diff the root file-system
including tracking deleted files.

Add an --ignore flag to podman rm and stop. When specified, Podman will
ignore "no such {container,pod}" errors that occur when a specified
container/pod is not present in the store (anymore).  The motivation
behind adding this flag is to write more robust systemd services using
Podman.  A user might have manually decided to remove a container/pod
which would lead to a failure during the `ExecStop` directive of a
systemd service referencing that container/pod.
