The dependencies of the image-oci class were missed in
initial conversions.

OEcore/bitbake are moving to use the clearer ":" as an overrides
separator.
This is pass one of updating the meta-virt recipes to use that
syntax.
This has only been minimally build/runtime tested, more changes
will be required for missed overrides, or incorrect conversions
Note: A recent bitbake is required:

bitbake: data_smart/parse: Allow ':' characters in variable/function names
It is becomming increasingly clear we need to find a way to show what
is/is not an override in our syntax. We need to do this in a way which
is clear to users, readable and in a way we can transition to.
The most effective way I've found to this is to use the ":" charater
to directly replace "_" where an override is being specified. This
includes "append", "prepend" and "remove" which are effectively special
override directives.
This patch simply adds the character to the parser so bitbake accepts
the value but maps it back to "_" internally so there is no behaviour
change.
This change is simple enough it could potentially be backported to older
version of bitbake meaning layers using the new syntax/markup could
work with older releases. Even if other no other changes are accepted
at this time and we don't backport, it does set us on a path where at
some point in future we could
require a more explict syntax.
I've tested this patch by converting oe-core/meta-yocto to the new
syntax for overrides (9000+ changes) and then seeing that builds
continue to work with this patch.

As part of allowing different types of oci images to be created,
we split our IMG_cmd into .inc files that can then be specific to
the selected type.
For the umoci backend: We can take the same options as sloci
expects and use umoci to create images.
The resulting OCI image is similar, but by using umoci, we set
the stage to do multi-tag, or multi-layer images in the future.
But for now, we are functionally equivalent to the sloci backend.

This image class creates an oci image spec directory from a generated
rootfs. The contents of the rootfs do not matter (i.e. they need not be
container optimized), but by using the container image type and small
footprint images, we can create directly executable container images.
Once the tarball (or oci image directory) has been created of the OCI
image, it can be manipulated by standard tools. For example, to create a
runtime bundle from the oci image, the following can be done:
Assuming the image name is "container-base":
If the oci image was a tarball, extract it (skip, if a directory is being directly used)
% tar xvf container-base-<arch>-<stamp>.rootfs-oci-latest-x86_64-linux.oci-image.tar
And then create the bundle:
% oci-image-tool create --ref name=latest container-base-<arch>-<stamp>.rootfs-oci container-base-oci-bundle
Or to copy (push) the oci image to a docker registry, skopeo can be used (vary the
tag based on the created oci image:
% skopeo copy --dest-creds <username>:<password> oci:container-base-<arch>-<stamp>:latest docker://zeddii/container-base
The following image variables are available to customize the details
of the constructed image (defaults as shown):
OCI_IMAGE_AUTHOR ?= "${PATCH_GIT_USER_NAME}"
OCI_IMAGE_AUTHOR_EMAIL ?= "${PATCH_GIT_USER_EMAIL}"
OCI_IMAGE_TAG ?= "latest"
OCI_IMAGE_RUNTIME_UID ?= ""
OCI_IMAGE_ARCH ?= "${TARGET_ARCH}"
OCI_IMAGE_SUBARCH ?= "${@oci_map_subarch(d.getVar('TARGET_ARCH'), d.getVar('TUNE_FEATURES'), d)}"
OCI_IMAGE_ENTRYPOINT ?= "sh"
OCI_IMAGE_ENTRYPOINT_ARGS ?= ""
OCI_IMAGE_WORKINGDIR ?= ""
//List of ports to expose from a container running this image:
//PORT[/PROT]
// format: <port>/tcp, <port>/udp, or <port> (same as <port>/tcp).
OICI_IMAGE_PORTS ?= ""
// key=value list of labels
OCI_IMAGE_LABELS ?= ""
// key=value list of environment variables
OCI_IMAGE_ENV_VARS ?= ""
