Implement `podman-remote cp` and break out the logic from the previously
added `pkg/copy` into it's basic building blocks and move them up into
the `ContainerEngine` interface and `cmd/podman`.
The `--pause` and `--extract` flags are now deprecated and turned into
nops.
Note that this commit is vendoring a non-release version of Buildah to
pull in updates to the copier package.

Introduce a `Copier` object to separate the copy-rule enforcement from
copying. That allows for a better error reporting of the REST API.

Move handling the stat header into `pkg/copy`. All copy-related should
ideally be located in this package to increase locality and reduce
scattering where possible.

Add an API for parsing user input into a possibly specified container
and path. This allows for sharing the parsing code between the local
and the remote client (and bindings) in the future.

* Add a new `pkg/copy` to centralize all container-copy related code.
* The new code is based on Buildah's `copier` package.
* The compat `/archive` endpoints use the new `copy` package.
* Update docs and an several new tests.
* Includes many fixes, most notably, the look-up of volumes and mounts.
Breaking changes:
* Podman is now expecting that container-destination paths exist.
Before, Podman created the paths if needed. Docker does not do
that and I believe Podman should not either as it's a recipe for
masking errors. These errors may be user induced (e.g., a path
typo), or internal typos (e.g., when the destination may be a
mistakenly unmounted volume). Let's keep the magic low for such
a security sensitive feature.
