logs: support --tail 0
change the default to -1, so that we can change the semantic of
"--tail 0" to not print any existing log line.

Matthew Heon 6f630bc09b Move OCI runtime implementation behind an interface
For future work, we need multiple implementations of the OCI
runtime, not just a Conmon-wrapped runtime matching the runc CLI.

As part of this, do some refactoring on the interface for exec
(move to a struct, not a massive list of arguments). Also, add
'all' support to Kill and Stop (supported by runc and used a bit
internally for removing containers).

Marco Vedovati dacbc5beb2 rm: add containers eviction with `rm --force`
Add ability to evict a container when it becomes unusable. This may
happen when the host setup changes after a container creation, making it
impossible for that container to be used or removed.
Evicting a container is done using the `rm --force` command.

Add new exit codes to rm & rmi for running containers & dependencies
This enables programs and scripts wrapping the podman command to handle
'podman rm' and 'podman rmi' failures caused by paused or running
containers or due to images having other child images or dependent
containers. These errors are common enough that it makes sense to have
a more machine readable way of detecting them than parsing the standard
error output.

Matthew Heon 1e3e99f2fe Move the HostConfig portion of Inspect inside libpod
When we first began writing Podman, we ran into a major issue
when implementing Inspect. Libpod deliberately does not tie its
internal data structures to Docker, and stores most information
about containers encoded within the OCI spec. However, Podman
must present a CLI compatible with Docker, which means it must
expose all the information in 'docker inspect' - most of which is
not contained in the OCI spec or libpod's Config struct.

Our solution at the time was the create artifact. We JSON'd the
complete CreateConfig (a parsed form of the CLI arguments to
'podman run') and stored it with the container, restoring it when
we needed to run commands that required the extra info.

Over the past month, I've been looking more at Inspect, and
refactored large portions of it into Libpod - generating them
from what we know about the OCI config and libpod's (now much
expanded, versus previously) container configuration. This path
comes close to completing the process, moving the last part of
inspect into libpod and removing the need for the create
artifact.

This improves libpod's compatability with non-Podman containers.
We no longer require an arbitrarily-formatted JSON blob to be
present to run inspect.

baude dd81a44ccf remove libpod from main
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).

Also, you can now podman-remote run -it.  There are some bugs that need
to be ironed out but I would prefer to merge this so we can make both
progress on start and exec as well as the bugs.

* when doing podman-remote run -it foo /bin/bash, you have to press
enter to get the prompt to display. with the localized podman, we had to
teach it connect to the console first and then start the container so we
did not miss anything.

* when executing "exit" in the console, we get a hard lockup likely
because nobody knows what to do.

* custom detach keys are not supported

* podman-remote run -it alpine ls does not currently work.  only

Peter Hunt 81804fc464 pod infra container is started before a container in a pod is run, started, or attached.
Prior, a pod would have to be started immediately when created, leading to confusion about what a pod state should be immediately after creation. The problem was podman run --pod ... would error out if the infra container wasn't started (as it is a dependency). Fix this by allowing for recursive start, where each of the container's dependencies are started prior to the new container. This is only applied to the case where a new container is attached to a pod.

Also rework container_api Start, StartAndAttach, and Init functions, as there was some duplicated code, which made addressing the problem easier to fix.
