With additional stores there is a risk that you could have
multiple images with the same name. IE An older image in a
read/only store versus a newer version in the read/write store.
This patch will ignore multiple images with the same name iff
one is read/write and all of the others are read/only.

This change was missed in pull/8689. Now that volume pruneing supports
filters system pruneing can pass its filters down to the volume
pruneing. Additionally this change adds tests for the following components
* podman system prune subcommand with `--volumes` & `--filter` options
* apiv2 api tests for `/system/` and `/libpod/system` endpoints

`podman network create` should always add a gateway to the cni config.
If no gateway is given use the first ip in the subnet. CNI does not require
the gateway field but we need it because of network inspect.
This worked with previous version but was dropped in Commit(e7a72d72fd).

* Adds `--filter` support to podman volume prune cli
* Adds `?filters...` support to podman volume prune api
* Updates apiv2 / e2e tests

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.

Just checking for `rootless.IsRootless()` does not catch all the
cases where slirp4netns is in use - we actually allow it to be
used as root as well. Fortify the conditional here so we don't
fail in the root + slirp case.

This adds a new command, 'podman network reload', to reload the
networks of existing containers, forcing recreation of firewall
rules after e.g. `firewall-cmd --reload` wipes them out.
Under the hood, this works by calling CNI to tear down the
existing network, then recreate it using identical settings. We
request that CNI preserve the old IP and MAC address in most
cases (where the container only had 1 IP/MAC), but there will be
some downtime inherent to the teardown/bring-up approach. The
architecture of CNI doesn't really make doing this without
downtime easy (or maybe even possible...).
At present, this only works for root Podman, and only locally.
I don't think there is much of a point to adding remote support
(this is very much a local debugging command), but I think adding
rootless support (to kill/recreate slirp4netns) could be
valuable.

Podman pre-1.8 also included a field with this name, which was a
String. Podman 2.2.0 added a new field reusing the name but as a
Struct. This completely broke JSON decode for pre-1.8 containers
in Podman 2.2, resulting in completely broken behavior.
Re-name the JSON field and add a note that the old name should
not be re-used to prevent this problem from re-occurring. This
will still result in containers from 2.2.0 being broken
(specifically, containers with image volumes will have them
disappear) but this is the lesser of two evils.

Installing a duplicate shutdown handler fails, but if a handler
with the same name is already present, we should be set to go.
There's no reason to print a user-facing error about it.
This comes up almost nowhere because Podman never makes more than
one Libpod runtime, but there is one exception (`system reset`)
and the error messages, while harmless, were making people very
confused (we got several bug reports that `system reset` was
nonfunctional).

Short-name aliasing was introduced with Podman 2.2 as an opt-in preview
by enabling an environment variable. Now, as we're preparing for the
3.0 release, we can enable short-name aliasing by default. Opting out
can be done by configuring the `registries.conf` config file.

* 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.

Our users are missing certain warning messages that would
make debugging issues with Podman easier.
For example if you do a podman build with a Containerfile
that contains the SHELL directive, the Derective is silently
ignored.
If you run with the log-level warn you get a warning message explainging
what happened.
