the compilation demands of having libpod in main is a burden for the
remote client compilations. to combat this, we should move the use of
libpod structs, vars, constants, and functions into the adapter code
where it will only be compiled by the local client.
this should result in cleaner code organization and smaller binaries. it
should also help if we ever need to compile the remote client on
non-Linux operating systems natively (not cross-compiled).

In cases where the remote client culls options to a command, we need to
be sure that the lookup for that flag does not result in a nil pointer.
To do so, we add a Remote attribute to the podman struct and then cli
helper funcs are now aware they are remote.

simplify the rootless implementation to use a single user namespace
for all the running containers.
This makes the rootless implementation behave more like root Podman,
where each container is created in the host environment.
There are multiple advantages to it: 1) much simpler implementation as
there is only one namespace to join. 2) we can join namespaces owned
by different containers. 3) commands like ps won't be limited to what
container they can access as previously we either had access to the
storage from a new namespace or access to /proc when running from the
host. 4) rootless varlink works. 5) there are only two ways to enter
in a namespace, either by creating a new one if no containers are
running or joining the existing one from any container.
Containers created by older Podman versions must be restarted.

in the few places where we care about skipping the storage
initialization, we can simply use the process effective UID, instead
of relying on a global boolean flag.

in the case of the remote-client, it was decided to hide the latest
flag to avoid confusion for end-users on what the "last" container,
volume, or pod are.

Subcommands should not be showing the global flags. This causes the important

In the previous CLI, we had an accurate depiction of commands
available for the remote client and those available for the

We intend to migrate to the cobra cli from urfave/cli because the
project is more well maintained. There are also some technical reasons
as well which extend into our remote client work.

This patch forces them all to be capatilized.

With rootless containers we cannot really restart an existing container
as we would need to join the mount namespace as well to be able to reuse
the storage, so ensure the container is stopped first.

We now can remove a paused container by sending it a kill signal while it
is paused. We then unpause the container and it is immediately killed.
Also, reworked how the parallelWorker results are handled to provide a
more consistent approach to how each subcommand implements it. It also
fixes a bug where if one container errors, the error message is duplicated
when printed out.

When attempting to restart many containers, we can benefit from making
the restarts parallel. For convenience, two new options are added:
--all attempts to restart all containers
--run-only when used with --all will attempt to restart only running containers

Don't print potentially verbose help messages in case of usage errors,
but print only the usage error followed by a pointer to the command's
help. This aligns with Docker.

$ podman run -h

first pass at adding in the container related endpoints/methods for the libpod
backend. Couple of important notes:
* endpoints that can use a console are not going to be done until we have "remote" console
* several of the container methods should probably be able to stream as opposed to a one-off return

implement varlink image functions for working with libpod with the exception of a
couple due to incompletions on the libpod side of things (build).
also, created a first pass at a libpodpy package which will stand as a client to
working with libpod's varlink methods using python.
