prevent opening the same file twice, since we re-exec podman in
rootless mode. While at it, also solve a possible race between the
check for the file and writing to it. Another process could have
created the file in the meanwhile and we would just end up overwriting
it.

when reading the output from conmon using the JSON methods, it appears that
JSON marshalling is higher in pprof than it really is because the pipe is
"waiting" for a response. this gives us a clearer look at the real CPU/time
consumers.

This removes duplicate code paths which has been previously factored out
as getAllOrLatestContainers().

Instead of duplicating the same code in multiple commands this uses the
newly added function checkAllAndLatest() instead.
Signed-off-by: Adrian Reber <areber@redhat.com>
Just as the checkAllAndLatest() function the new code in
getAllOrLatestContainers() is used in some commands and duplicated. This
factors out this code to be used in other places without duplicating it.

The check about the --all and --latest option is used and repeated and
some commands. Factor it out and put it into common.

We probably won't be able to initialize a firewall plugin when we
are not running as root, so we shouldn't even try. Replace the
less-effect EUID check with the rootless package's better check
to make sure we don't accidentally set up the firewall in these
cases.

Fix the parsing of environment variables to catch invalid ones, such as
`-e = ` or `-e =A`, early in the stack to return meaningful error
messages. Also, instead of erroring out, set unspecified env variables
as empty (e.g., `-e FOO`) to remain compatible with Docker.

The newly introduced CRIU version check is now used to make sure
checkpointing and restoring is only used if the CRIU version is new
enough.

I've seen a runc zombie process hanging around, it is caused by not
cleaning up the "$OCI status" process. Also adjust another location
that has the same issue.

when doing stats -a|--all, if you have non-running containers, we should
not error on not being able to get information like PID, etc on them.

When doing rm, we now parallelize the actual conainter deletions so they
can complete faster. This speeds up operations like rm -a.

Running 'podman port -l' on a system without any containers created
gives:
$ podman port -l
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x10 pc=0xf3cef1]
goroutine 1 [running]:

This fixes it by making sure the variable 'containers' is nil and not [<nil>].
