The check for net=none was wrong. It just assumed when we do not create
the netns but have one set that we use the none mode. This however also
applies to a container which joins the pod netns.
To correctly check for the none mode use `config.NetMode.IsNone()`.

We do not use the ocicni code anymore so let's get rid of it. Only the
port struct is used but we can copy this into libpod network types so
we can debloat the binary.
The next step is to remove the OCICNI port mapping form the container
config and use the better PortMapping struct everywhere.

Make use of the new network interface in libpod.
This commit contains several breaking changes:
- podman network create only outputs the new network name and not file
path.
- podman network ls shows the network driver instead of the cni version
and plugins.
- podman network inspect outputs the new network struct and not the cni
conflist.
- The bindings and libpod api endpoints have been changed to use the new
network structure.
The container network status is stored in a new field in the state. The
status should be received with the new `c.getNetworkStatus`. This will
migrate the old status to the new format. Therefore old containers should
contine to work correctly in all cases even when network connect/
disconnect is used.
New features:
- podman network reload keeps the ip and mac for more than one network.
- podman container restore keeps the ip and mac for more than one
network.
- The network create compat endpoint can now use more than one ipam
config.
The man pages and the swagger doc are updated to reflect the latest
changes.

When configs are loaded from disk we need to check if they contain a
ipv6 subnet and set ipv6 enables to true in this case.

The default network should not be validated against used subnets, we have to ensure
that this network can always be created even when a subnet is already used on the host.
This could happen if you run a container on this net, then the cni interface will be
created on the host and "block" this subnet from being used again.
Therefore the next podman command tries to create the default net again and it would
fail because it thinks the network is used on the host.

For rootful users ports are forwarded via iptables. To make sure no
other process tries to use them, libpod will bind the ports and pass the
fds to conmon. There seems to be race when a container is restarted
because libpod tries to bind the port before the conmon process exited.
The problem only hapens with the podman service because it keeps the
connection open. Once we have the fd and passed it to conmon the
podman service should close the connection.
To verify run `sudo ss -tulpn` and check that only the conmon process
keeps the port open. Previously you would also see the podman server
process listed.

Kubernetes has a concept of init containers that run and exit before
the regular containers in a pod are started. We added init containers
to podman pods as well. This patch adds support for generating init
containers in the kube yaml when a pod we are converting had init
containers. When playing a kube yaml, it detects an init container
and creates such a container in podman accordingly.
Note, only init containers created with the init type set to "always"
will be generated as the "once" option deletes the init container after
it has run and exited. Play kube will always creates init containers
with the "always" init container type.

The rootless integration tests show the XDG_RUNTIME_DIR warning without
any reasons. Podman runs without problems in these and yet the warning

create the runroot directory.

The conmon buffer size is 8192, however the attach socket needs two extra
bytes. The first byte of each message will be the STREAM type. The last
byte is a null byte. So when we want to read 8192 message bytes we need
to read 8193 bytes since the first one is special.
check 1ef246896b/src/ctr_stdio.c (L101-L107)
This problem can be seen in podman-remote run/exec when it prints output
with 8192 or more bytes. The output will miss the 8192 byte.

Creating the rootlessport socket can fail with `bind: invalid argument`
when the socket path is longer than 108 chars. This is the case for
users with a long runtime directory.
Since the kernel does not allow to use socket paths with more then 108
chars use a workaround to open the socket path.
