Refactor for specialized libpod engines
add the ability to prune images, volumes, containers, and pods
Signed-off-by: baude <bbaude@redhat.com>
Continue the refactoring of image removal. I didn't manage to break all
the following changes into smaller and easier to digest commits due to
time constraints:
* Return an error slice instead of a single error. Use multierror only
in the client/frontend. Reflect that in the types.
* Use the batch image removal in the client while preserving the more
rest-idiomatic single-image removal endpoint.
* Add a new handler for the single-image removal endpoint to make it
share the same code as the batch endpoint.
* Expose bindings for the single and batch endpoints, so we can
properly test them.
* Add several convenience functions for error handling to
pkg/errorhandling.
* Set the correct error type in libpod to set the exit code to 2 when
one or more containers are using an image.
* Massage the bindings tests a bit and tackle compilation errors.

For (almost) all commands which podman passes on to a OCI runtime
XDG_RUNTIME_DIR is set to the same value. This does not happen for the
checkpoint command.
Using crun to checkpoint a container without this change will lead to
crun using XDG_RUNTIME_DIR of the currently logged in user and so it
will not find the container Podman wants to checkpoint.
This bascially just copies a few lines from on of the other commands to
handle 'checkpoint' as all the other commands.
Thanks to Giuseppe for helping me with this.
For 'restore' it is not needed as restore goes through conmon and for
calling conmon Podman already configures XDG_RUNTIME_DIR correctly.

Podman was checking if the runtime support checkpointing by running
'runtime checkpoint -h'. That works for runc.
crun, however, does not use '-h, --help' for help output but, '-?,
--help'.
This commit switches both checkpoint support detection from
'runtime checkpoint -h'
to
'runtime checkpoint --help'.
Podman can now correctly detect if 'crun' also support checkpointing.

When creating a network we pass down a name which end up in the
K8S_POD_NAME argument to cni plugins. Currently this name is always
filled with the container name, so for pods it is the name of the
infra container, not really what one would expect.
This mess up with the dnsname plugin as it doesn't receive the pod
name in K8S_POD_NAME. To fix this pass the pod name when the container
is part of a pod, otherwise use the container name like before.

We previously tried to send resize events only after the exec
session successfully started, which makes sense (we might drop an
event or two that came in before the exec session started
otherwise). However, the start function blocks, so waiting
actually means we send no resize events at all, which is
obviously worse than losing a few.. Sending resizes before attach
starts seems to work fine in my testing, so let's do that until we
get bug reports that it doesn't work.

We previously attempted to work within CNI to do this, without

allocations which, for various reasons, are not stored in tmpfs
and persist through reboot.

This produces detailed information about the configuration of an
exec session in a format suitable for the new HTTP API.
Signed-off-by: Matthew Heon <matthew.heon@pm.me>
As part of the rework of exec sessions, we need to address them
independently of containers. In the new API, we need to be able
to fetch them by their ID, regardless of what container they are
associated with. Unfortunately, our existing exec sessions are
tied to individual containers; there's no way to tell what
container a session belongs to and retrieve it without getting
every exec session for every container.
This adds a pointer to the container an exec session is
associated with to the database. The sessions themselves are
still stored in the container.
Exec-related APIs have been restructured to work with the new
database representation. The originally monolithic API has been
split into a number of smaller calls to allow more fine-grained
control of lifecycle. Support for legacy exec sessions has been
retained, but in a deprecated fashion; we should remove this in
a few releases.

Add support to auto-update containers running in systemd units as
generated with `podman generate systemd --new`.
`podman auto-update` looks up containers with a specified
"io.containers.autoupdate" label (i.e., the auto-update policy).
If the label is present and set to "image", Podman reaches out to the
corresponding registry to check if the image has been updated. We
consider an image to be updated if the digest in the local storage is
different than the one of the remote image. If an image must be
updated, Podman pulls it down and restarts the container. Note that the
restarting sequence relies on systemd.
At container-creation time, Podman looks up the "PODMAN_SYSTEMD_UNIT"
environment variables and stores it verbatim in the container's label.
This variable is now set by all systemd units generated by
`podman-generate-systemd` and is set to `%n` (i.e., the name of systemd
unit starting the container). This data is then being used in the
auto-update sequence to instruct systemd (via DBUS) to restart the unit
and hence to restart the container.
Note that this implementation of auto-updates relies on systemd and
requires a fully-qualified image reference to be used to create the
container. This enforcement is necessary to know which image to
actually check and pull. If we used an image ID, we would not know
which image to check/pull anymore.

Until now, we've been validating every part of container
configuration through the With... functions that set the options.
This if fine when we are just validating the options to an
individual function, but things get complicated once we need to
validate conflicts between different options. We don't know the
order in which things were passed, so we need the validation on
both of the potential options that can conflict, resulting in
significant code duplication. To solve this, add a validate()
function for containers, and use this to check whether everything
is in a good state.
We can probably move more into this function (there are other
parts of container creation that also do validation of a sort)
but this is a good start to simplifying our options.

Before Libpod supported named volumes, we approximated image
volumes by bind-mounting in per-container temporary directories.
This was handled by Libpod, and had a corresponding database
entry to enable/disable it.
However, when we enabled named volumes, we completely rewrote the
old implementation; none of the old bind mount implementation
still exists, save one flag in the database. With nothing
remaining to use it, it has no further purpose.
