log_path is currently set at the client side and is ignored by
the server in a remote session. This leads to either incorrect log_path
being considered by the server or not honored at all. Move the handling
from client to the server, in line with other flags such as log_driver.

This was implemented by containers/netavark #1369; this commit
completes the process by wiring it into Podman. We now respect
the CLI order for configured networks - if a user passes
`--net net1,net2` we guarantee that net1 will be configured
before net2.
For containers created before this patch, we don't retain enough
information to configure networks in CLI order, so we use
alphabetical order instead to still guarantee consistency.
No breaking API changes have been made, but we do add a new
field to supplement the existing map to (optionally) provide
ordering information. The Podman CLI will always pass this.
Existing applications that do not will, again, receive]
deterministic ordering based on an alphabetical sort of network
names.
This requires the latest version of Netavark to work properly.

The systemd timer created for health checks did not pass global
podman flags to the subprocess, causing it to use default storage
settings instead of matching the parent process. This is most
visible with --transient-store, where the healthcheck looks up
the container in the default store instead of the volatile one.
Extract GlobalPodmanArgs() from CreateExitCommandArgs so both the
exit command and healthcheck timer share the same set of global
flags (--root, --runroot, --transient-store, --storage-driver, etc.).

Add a per-volume 'nocreate' option that prevents automatic creation of
named volumes when they don't exist. When specified, Podman will fail
if the volume is not found instead of creating it automatically.
Usage: -v myvolume:/data:nocreate
--mount type=volume,src=myvolume,dst=/data,nocreate

ConfigToSpec() serializes the container config to JSON and deserializes
it into a SpecGenerator. Both structs use the JSON tag "secret_env" but
with incompatible types: the container config uses map[string]*secrets.Secret
(complex objects) while the specgen uses map[string]string (env var name
to secret name). This causes an unmarshal error when cloning containers
that use --secret with type=env.
Fix this by saving and clearing EnvSecrets before JSON marshal (same
pattern as existing tmpSystemd/tmpMounts), then converting the secret
objects to name strings and assigning them to the specgen afterward.
Also fix FillOutSpecGen to not overwrite env secrets populated by
ConfigToSpec when no new secrets are provided on the command line.

Remove CNI-specific conditional logic and update comments throughout
the libpod networking code:
- Simplified DNS configuration logic in container_internal_common.go
to always use netavark behavior (removed backend checks)
- Removed CNI-specific iptables chain error regex pattern
- Updated all comments referencing 'CNI' to use 'netavark' or
'network backend'
- Renamed variable 'cniNet' to 'netInfo' for clarity
- Updated field and type documentation to remove CNI references
All networking code now assumes netavark as the sole backend.

Remove user-facing CLI options for CNI network backend:
CLI flags:
- Keep --network-backend global flag as hidden and deprecated for
backward compatibility with cleanup commands from 5.x containers
- Map flag to a throwaway variable (value is ignored)
- Remove shell completion for network backend values
Shell completions:
- Remove AutocompleteNetworkBackend() function
- Remove references to CNI and Netavark type constants
Backward compatibility:
- Remove --rootless-cni flag alias for podman unshare
- Remove SetNormalizeFunc that mapped rootless-cni to rootless-netns
- Update --rootless-netns flag description to mention only netavark
The --network-backend flag remains as a hidden deprecated flag to
prevent failures when upgrading from 5.x where containers may have
cleanup commands that include this flag. The flag is accepted but
ignored. Users can no longer specify CNI as a network backend option.
The --rootless-cni alias is removed; users must use --rootless-netns.

This also includes a number of significant changes to the SQLite
state made possible by removal of the legacy DB.
1. Enable database unit tests for SQLite state, with numerous
tweaks to get tests passing. Most notable changes are to
container removal - where we previously didn't return an error
if there was no container to remove - and RemovePodContainers,
which I don't think ever worked properly from my reading of
the failures.
2. Removal of AddContainerToPod/RemoveContainerToPod. On SQLite,
these functions are identical to AddContainer/RemoveContainer
and there is no reason to retain duplicates.
3. Removal of SafeRewriteContainerConfig - it's identical to
RewriteContainerConfig in SQLite, no reason to have duplicate
entrypoints.
As an exciting side-note, this removes Podman's requirement that
containers and pods cannot share a name, which was a BoltDB
restriction only.

Added log_path variable in containers/common, User sets default log path in containers.conf under the `[containers]` section.
The directory has to exist beforehand. Container logs go under this directory, sub-directories named with the container id
and inside the sub-directory a ctr.log file will be created where the container logs for the corresponding container will go.
This path can be overridden by using the `--log-opt` flag.

An artifact without the title annoation just gets the digest as name
which is less than ideal. While it is a decent default to avoid
conflicts users would like to configure the name.
With the name=abc option we will call the file abc in case of a signle
artifact and otherwise we use abc-x where x is the layer index starting
at 0 to avoid conflicts.

Add a new option to allow for mounting artifacts in the container, the
syntax is added to the existing --mount option:
type=artifact,src=$artifactName,dest=/path[,digest=x][,title=x]
This works very similar to image mounts. The name is passed down into
the container config and then on each start we lookup the artifact and
the figure out which blobs to mount. There is no protaction against a
user removing the artifact while still being used in a container. When
the container is running the bind mounted files will stay there (as the
kernel keeps the mounts active even if the bind source was deleted).
On the next start it will fail to start as if it does not find the
artifact. The good thing is that this technically allows someone to
update the artifact with the new file by creating a new artifact with
the same name.

New flags in a `podman update` can change the configuration of HealthCheck when the container is started, without having to restart or recreate the container.
This can help determine why a given container suddenly started failing HealthCheck without interfering with the services it provides. For example, reconfigure HealthCheck to keep logs longer than the usual last X results, store logs to other destinations, etc.

All the backend work was done a while back for image volumes, so
this is effectively just plumbing the option in for volumes in
the parser logic. We do need to change the return type of the
volume parser as it only worked on spec.Mount before (which does
not have subpath support, so we'd have to pass it as an option
and parse it again) but that is cleaner than the alternative.

Similar to github.com/containers/buildah/pull/5761 but not
security critical as Podman does not have an expectation that
mounts are scoped (the ability to write a --mount option is
already the ability to mount arbitrary content into the container
so sneaking arbitrary options into the mount doesn't have
security implications). Still, bad practice to let users inject
anything into the mount command line so let's not do that.
