Dockerfile's ENTRYPOINT statement supports also a list of strings. This
patch implements this behavior for oci-container-configuration.

* oci/services/containers.scm (string-or-list-of-strings?): New
procedure.
(oci-container-configuration)[entrypoint]: Change field type to
maybe-string-or-list-of-strings.
(oci-container-configuration->options): Use it.

This commit allows oci-image records to be directly compiled to tarballs
file names when ungexeped, by means of a gexp compiler. It is supposed
to make the usage of oci-images in gexp smoother.

* oci/services/containers.scm (lower-manifest): Reformat and derive
tarball name from the image reference.
(lower-oci-image-state): Drop procedure and merge with lower-oci-image.
(oci-image-compiler): Implement in terms of lower-oci-image.
(oci-image-loader): Drop call to lower-oci-image and directly ungexp the
oci-image record.

This patch allows containers run with podman to run each with their own
specific user.

* doc/guix.texi: Fix wrong type for oci-container-configuration's
shepherd-dependencies field.
* gnu/services/containers.scm (oci-container-shepherd-service): In case
a specific container is not run through the user provisioned by the
oci-service-type, its environment is different from the globally
provisioned one and must be recomputed.

This patch implements a generalization of the
oci-container-service-type, which consequently is made deprecated.  The
oci-service-type, in addition to all the features from the
oci-container-service-type, can now provision OCI networks and volumes.
It only handles OCI objects creation, the user is supposed to handle
state once the objects are provsioned.

It currently supports two different OCI runtimes: Docker and rootless
Podman.  Both runtimes are tested to make sure provisioned containers
can connect to each other through provisioned networks and can
read/write data with provisioned volumes.

At last the Scheme API is thought to facilitate the implementation of a
Guix Home service in the future.

* gnu/build/oci-containers.scm: New file containg OCI runtime business
logic used in OCI backed Shepherd services.

(image-reference): Implement unambiguous naming convention, that paired
with the new implementation for listing caches images with docker ls or
podman ls, allows for more efficient image caching.
(oci-container-configuration)[user,group]: Change default-type to
maybe-string, since by default containers will run under the user and
group declared in oci-configuration records. When unset the
oci-service-type will derive their value from the OCI runtime state.

define a predicate and use it as a type in the configuration.  This

This patch moves the oci-container-configuration and related
configuration records to (gnu services containers).
Public symbols are still exported for backwards
compatibility but since the oci-container-service-type will be
deprecated in favor of the more general oci-service-type, everything is
moved outside of the docker related module.

* gnu/services/docker.scm: Move everything related to oci-container-configuration
to...
* gnu/services/containers.scm: ...here.scm.
