When doing a podman images, manifests lists look just like images, so
it is logical that users would assume that they can just podman push them
to a registry. The problem is we throw out weird errors when this happens
and users need to somehow figure out this is a manifest list rather then
an image, and frankly the user will not understand the difference.
This PR will make podman push just do the right thing, by failing over and
attempting to push the manifest if it fails to push the image.
Fix up handling of manifest push
Protocol should bring back a digest string, which can either be
printed or stored in a file.
We should not reimplement the manifest push setup code in the tunnel
code but take advantage of the api path, to make sure remote and local
work the same way.

Basic theory: We remove the container, but *only from the DB*.
We leave it in c/storage, we leave the lock allocated, we leave
it running (if it is). Then we create an identical container with
an altered name, and add that back to the database. Theoretically
we now have a renamed container.
The advantage of this approach is that it doesn't just apply to
rename - we can use this to make *any* configuration change to a
container that does not alter its container ID.
Potential problems are numerous. This process is *THOROUGHLY*
non-atomic at present - if you `kill -9` Podman mid-rename things
will be in a bad place, for example. Also, we can't rename
containers that can't be removed normally - IE, containers with
dependencies (pod infra containers, for example).
The largest potential improvement will be to move the majority of
the work into the DB, with a `RecreateContainer()` method - that
will add atomicity, and let us remove the container without
worrying about depencies and similar issues.
Potential problems: long-running processes that edit the DB and
may have an older version of the configuration around. Most
notable example is `podman run --rm` - the removal command needed
to be manually edited to avoid this one. This begins to get at
the heart of me not wanting to do this in the first place...
This provides CLI and API implementations for frontend, but no
tunnel implementation. It will be added in a future release (just
held back for time now - we need this in 3.0 and are running low
on time).
This is honestly kind of horrifying, but I think it will work.

This implements support for mounting and unmounting volumes
backed by volume plugins. Support for actually retrieving
plugins requires a pull request to land in containers.conf and
then that to be vendored, and as such is not yet ready. Given
this, this code is only compile tested. However, the code for
everything past retrieving the plugin has been written - there is
support for creating, removing, mounting, and unmounting volumes,
which should allow full functionality once the c/common PR is
merged.
A major change is the signature of the MountPoint function for
volumes, which now, by necessity, returns an error. Named volumes
managed by a plugin do not have a mountpoint we control; instead,
it is managed entirely by the plugin. As such, we need to cache
the path in the DB, and calls to retrieve it now need to access
the DB (and may fail as such).
Notably absent is support for SELinux relabelling and chowning
these volumes. Given that we don't manage the mountpoint for
these volumes, I am extremely reluctant to try and modify it - we
could easily break the plugin trying to chown or relabel it.
Also, we had no less than *5* separate implementations of
inspecting a volume floating around in pkg/infra/abi and
pkg/api/handlers/libpod. And none of them used volume.Inspect(),
the only correct way of inspecting volumes. Remove them all and
consolidate to using the correct way. Compat API is likely still
doing things the wrong way, but that is an issue for another day.

When migrating a container with associated volumes, the content of
these volumes should be made available on the destination machine.
This patch enables container checkpoint/restore with named volumes
by including the content of volumes in checkpoint file. On restore,
volumes associated with container are created and their content is
restored.
The --ignore-volumes option is introduced to disable this feature.
Example:
# podman container checkpoint --export checkpoint.tar.gz <container>
The content of all volumes associated with the container are included
in `checkpoint.tar.gz`
# podman container checkpoint --export checkpoint.tar.gz --ignore-volumes <container>
The content of volumes is not included in `checkpoint.tar.gz`. This is
useful, for example, when the checkpoint/restore is performed on the
same machine.
# podman container restore --import checkpoint.tar.gz
The associated volumes will be created and their content will be
restored. Podman will exit with an error if volumes with the same
name already exist on the system or the content of volumes is not
included in checkpoint.tar.gz
# podman container restore --ignore-volumes --import checkpoint.tar.gz
Volumes associated with container must already exist. Podman will not
create them or restore their content.

This change adds code to report the reclaimed space after a prune.
Reclaimed space from volumes, images, and containers is recorded
during the prune call in a PruneReport struct. These structs are
collected into a slice during a system prune and processed afterwards
to calculate the total reclaimed space.

Begin the migration of the image bindings for podman 3.0. this includes
the use of options for each binding. build was intentionally not
converted as I believe it needs more discussion before migration.
specifically, the build options themselves.
also noteworthly is that the remove image and remove images bindings
were merged into one. the remove images (or batch remove) has one
downside in that the errors return no longer adhere to http return
codes. this should be discussed and reimplemented in subsequent code.

The podman events aren't read until the given timestamp if the
timestamp is in the future. It just reads all events until now
and exits afterwards.
This does not make sense and does not match docker. The correct
behavior is to read all events until the given time is reached.
This fixes a bug where the wrong event log file path was used
when running first time with a new storage location.
Fixes#8694
This also fixes the events api endpoint which only exited when
an error occurred. Otherwise it just hung after reading all events.

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.
