Unlikely to happen but when there is an error printing the data to
stdout (either as json or go template) we should not just log it and
exit with 0. Instead return a proper error and exit with 125.

Currently the podman command --format output code uses a mix of
report.Formatter and report.Template.
I patched report.Formatter to correctly handle newlines[1]. Since we
cannot fix this with report.Template we have to migrate all users to
report.Formatter. This ensures consistent behavior for all commands.
This change does not change the output, we can add a new test for the
newline bug when the common PR is vendored in.

Currently podman events will just fail with `Error: failed to get journal
cursor: failed to get cursor: cannot assign requested address` when the
journal contains zero podman events.
The problem is that we are using the journal accessors wrong. There is no
need to call GetCursor() and compare them manually. The Next() return an
integer which tells if it moved to the next or not. This means the we can
remove GetCursor() which would fail when there is no entry.
This also includes another bug fix. Previously the logic called Next()
twice for the first entry which caused us to miss the first entry.
To reproduce this issue you can run the following commands:
```
sudo journalctl --rotate
sudo journalctl --vacuum-time=1s
```
Note that this will delete the full journal.
Now run podman events and it fails but with this patch it works.
Now generate a single event, i.e. podman pull alpine, and run
podman events --until 1s.
I am not sure how to get a reliable test into CI, I really do not want
to delete the journal and developer or CI systems.

podman --events-backend file events --stream=false should never hang. The
problem is that our tail library will wait for the file to be created
which makes sense when we do not run with --stream=false. To fix this we
can just always create the file when the logger is initialized. This
would also help to report errors early on in case the file is not
accessible.

This uses a jail to manage the container's network. Container jails for
all containers in a pod are nested within this and share the network
resources.
There is some code in networking_freebsd.go which is common with
networking_linux.go. Subsequent commits will move the shared code to
networking_common.go to reduce this duplication.

Podman adds an Error: to every error message. So starting an error
message with "error" ends up being reported to the user as
Error: error ...
This patch removes the stutter.
Also ioutil.ReadFile errors report the Path, so wrapping the err message
with the path causes a stutter.
