We now no longer write containers.conf, instead system connections and
farms are written to a new file called podman-connections.conf.
This is a major rework and I had to change a lot of things to get this
to compile again with my c/common changes.
It is a breaking change for users as connections/farms added before this
commit can now no longer be removed or modified directly. However because
the logic keeps reading from containers.conf the old connections can
still be used to connect to a remote host.

Add a new `no-dereference` mount option supported by crun 1.11+ to
re-create/copy a symlink if it's the source of a mount. By default the
kernel will resolve the symlink on the host and mount the target.
As reported in #20098, there are use cases where the symlink structure
must be preserved by all means.

This change is the first step of integrating appendable string arrays
into containers.conf and starts with enabling the `Env`, `Mounts`, and
`Volumes` fields in the `[Containers]` table.
Both, Buildah and Podman, read (and sometimes write) the fields of the
`Config` struct at various places, so I decided to migrate the fields
step-by-step. The ones in this change are most critical ones for
customers. Once all string slices/arrays are migrated, the docs of
containers.conf will be updated. The current changes are entirely
transparent to users.

As requested in containers/podman/issues/20000, add a `privileged` field
to the containers table in containers.conf. I was hesitant to add such
a field at first (for security reasons) but I understand that such a
field can come in handy when using modules - certain workloads require a
privileged container.

The processing and setting of the static and volume directories was
scattered across the code base (including c/common) leading to subtle
errors that surfaced in #19938.
There were multiple issues that I try to summarize below:
- c/common loaded the graphroot from c/storage to set the defaults for
static and volume dir. That ignored Podman's --root flag and
surfaced in #19938 and other bugs. c/common does not set the
defaults anymore which gives Podman the ability to detect when the
user/admin configured a custom directory (not empty value).
- When parsing the CLI, Podman (ab)uses containers.conf structures to
set the defaults but also to override them in case the user specified
a flag. The --root flag overrode the static dir which is wrong and
broke a couple of use cases. Now there is a dedicated field for in
the "PodmanConfig" which also includes a containers.conf struct.
- The defaults for static and volume dir and now being set correctly
and adhere to --root.
- The CONTAINERS_CONF_OVERRIDE env variable has not been passed to the
cleanup process. I believe that _all_ env variables should be passed
to conmon to avoid such subtle bugs.
Overall I find that the code and logic is scattered and hard to
understand and follow. I refrained from larger refactorings as I really
just want to get #19938 fixed and then go back to other priorities.
https://github.com/containers/common/pull/1659 broke three pkg/machine
tests. Those have been commented out until getting fixed.

When pulling from an OCI source, make sure to preseve the optional name.
For instance, a podman pull oci:/tmp/foo:quay.io/foo/bar:latest should
pull the image and name it quay.io/foo/bar:latest.
While at it, also fix a bug when pulling an OCI without the optional
name. Previously, we used the path to name the image which will error in
most cases due to invalid characters (e.g., capital ones). Hence, apply
the same trick as for the dir transport and generate a sha.

Support a new concept in containers.conf called "modules". A "module"
is a containers.conf file located at a specific directory. More than
one module can be loaded in the specified order, following existing
override semantics.
There are three directories to load modules from:
- $CONFIG_HOME/containers/containers.conf.modules
- /etc/containers/containers.conf.modules
- /usr/share/containers/containers.conf.modules
With CONFIG_HOME pointing to $HOME/.config or, if set, $XDG_CONFIG_HOME.
Absolute paths will be loaded as is, relative paths will be resolved
relative to the three directories above allowing for admin configs
(/etc/) to override system configs (/usr/share/) and user configs
($CONFIG_HOME) to override admin configs.

**podman compose** is a thin wrapper around an external compose provider
such as docker-compose or podman-compose. This means that `podman
compose` is executing another tool that implements the compose
functionality but sets up the environment in a way to let the compose
provider communicate transparently with the local Podman socket. The
specified options as well the command and argument are passed directly
to the compose provider.
The default compose providers are `docker-compose` and `podman-compose`.
If installed, `docker-compose` takes precedence since it is the original
implementation of the Compose specification and is widely used on the
supported platforms (i.e., Linux, Mac OS, Windows).
If you want to change the default behavior or have a custom installation
path for your provider of choice, please change the `compose_provider`
field in `containers.conf(5)`. You may also set the
`PODMAN_COMPOSE_PROVIDER` environment variable.

The --authfile flag has been ignored. Fix that and add a test to make
sure we won't regress another time. Requires a new --tls-verify flag

Also bump c/common since common/pull/1538 is required to correctly check

c/common as c/buildah would otherwise be moved back to 1.30.
