This allows us to run both the Libpod and Server handlers at the
same time without unregistering one.
Also, pass the signal that killed us into the handlers, in case
they want to use it to determine what to do (e.g. what exit code
to set).

we need to alter the return error message when a GET (inspect) is performed on an image using the compatibility layer. docker-py bindings look for a initial capped error message.

Expand the use of the Shutdown package such that we now use it
to handle signals any time we run Libpod. From there, add code to
container creation to use the Inhibit function to prevent a
shutdown from occuring during the critical parts of container
creation.
We also need to turn off signal handling when --sig-proxy is
invoked - we don't want to catch the signals ourselves then, but
instead to forward them into the container via the existing
sig-proxy handler.

We need a unified package for handling signals that shut down
Libpod and Podman. We need to be able to do different things on
receiving such a signal (`system service` wants to shut down the
service gracefully, while most other commands just want to exit)
and we need to be able to inhibit this shutdown signal while we
are waiting for some critical operations (e.g. creating a
container) to finish. This takes the first step by defining the
package that will handle this.

Currenly if a user specifies the name or ID of an external storage
container, we report an error to them.
buildah from scratch
working-container-2
podman rm working-container-2
Error: no container with name or ID working-container-2 found: no such container
Since the user specified the correct name and the container is in storage we
force them to specify --storage to remove it. This is a bad experience for the
user.
This change will just remove the container from storage. If the container
is known by libpod, it will remove the container from libpod as well.
The podman rm --storage option has been deprecated, and removed from docs.
Also cleaned documented options that are not available to podman-remote.

when using the compatibility mode as rootless, containers that were created were not setting their host names correctly due to the netmode not being set.

due to a lack of "locking" on cni operations, we could get ourselves in trouble when doing rapid creation or removal of networks. added a simple file lock to deal with the collision and because it is not considered a performent path, use of the file lock should be ok. if proven otherwise in the future, some generic shared memory lock should be implemented for libpod and also used here.
moved pkog/network to libpod/network because libpod is now being pulled into the package and it has therefore lost its generic nature. this will make it easier to absorb into libpod as we try to make the network closer to core operations.

Make Podman pod operations that do not involve starting
containers (which needs to be done in a specific order) use the
same parallel operation code we use to make `podman stop` on
large numbers of containers fast. We were previously stopping
containers in a pod serially, which could take up to the timeout
(default 15 seconds) for each container - stopping 100 containers
that do not respond to SIGTERM would take 25 minutes.
To do this, refactor the parallel operation code a bit to remove
its dependency on libpod (damn circular import restrictions...)
and use parallel functions that just re-use the standard
container API operations - maximizes code reuse (previously each
pod handler had a separate implementation of the container
function it performed).
This is a bit of a palate cleanser after fighting CI for two
days - nice to be able to return to a land of sanity.

In case os.Open[File], os.Mkdir[All], ioutil.ReadFile and the like
fails, the error message already contains the file name and the
operation that fails, so there is no need to wrap the error with
something like "open %s failed".
While at it
- replace a few places with os.Open, ioutil.ReadAll with
ioutil.ReadFile.
- replace errors.Wrapf with errors.Wrap for cases where there
are no %-style arguments.

Docker supports log-opt max_size and so does conmon (ALthough poorly).
Adding support for this allows users to at least make sure their containers
logs do not become a DOS vector.
