If no entrypoint or command is set in the podman create
command, and the image command or entrypoint is being
used as the default, then do not add the image command or
entrypoint to the generated kube yaml.
Kubernetes knows to default to the image command and/or
entrypoint settings when not defined in the kube yaml.
Add and modify tests for this case.

Don't use reexec for the rootlessport process, instead make it a
separate binary to reduce the memory usage. The problem with reexec is
that it will import all packages that podman uses and therefore loads a
lot of stuff into the heap. The rootlessport process however only needs
the rootlesskit library.
The memory usage is a concern since the rootlessport process will spawn
two process per container which has ports forwarded. The processes stay
until the container dies. On my laptop the current reexec version uses
47800 KB RSS. The new separate binary only uses 4540 KB RSS. This is
more than a 90% improvement.
The Makefile has been updated to compile the new binary and install it
to the libexec directory.

Vendor the latest HEAD in c/common to pull in changes for a faster
inspection of images. Previously, only the size computation was
optional, now the one for the parent image is as well.
In many cases, the parent image is not needed but it takes around 10ms
on my local machine. With this change, we cut off 10ms from many code
paths, most importantly, container creation.

There is a race where `conn.Close()` was called before `conn.CloseWrite()`.
In this case `CloseWrite` will fail and an useless error is printed. To
fix this we move the the `CloseWrite()` call to the same goroutine to
remove the race. This ensures that `CloseWrite()` is called before
`Close()` and never afterwards.
Also fixed podman-remote run where the STDIN was never was closed.
This is causing flakes in CI testing.

The backend for `ps --sync` has been nonfunctional for a long
while now - probably since v2.0. It's questionable how useful the
flag is in modern Podman (the original case it was intended to
catch, Conmon gone via SIGKILL, should be handled now via pinging
the process with a signal to ensure it's still alive) but having
the ability to force a refresh of container state from the OCI
runtime is still useful.
Signed-off-by: Matthew Heon <mheon@redhat.com>
This allows you to stop a container after a `podman stop` process
started, but did not finish, stopping the container (probably an
ignored stop signal, with no time to SIGKILL?). This is a very
narrow case, but once you're in it the only way to recover is a
`podman rm -f` of the container or extensive manual remediation
(you'd have to kill the container yourself, manually, and then
force a `podman ps --all --sync` to update its status from the
OCI runtime).
[NO NEW TESTS NEEDED] I have no idea how to verify this one -
we need to test that it actually started *during* the other stop
command, and that's nontrivial.

The current implementation of the CNI network interface only loads the
networks on the first call and saves them in a map. This is done to safe
performance and not having to reload all configs every time which will be
costly for many networks.
The problem with this approach is that if a network is created by
another process it will not be picked up by the already running podman
process. This is not a problem for the short lived podman commands but
it is problematic for the podman service.
To make sure we always have the actual networks store the mtime of the
config directory. If it changed since the last read we have to read
again.

When using play kube and generate kube, we need to support if bind
mounts have selinux options. As kubernetes does not support selinux in
this way, we tuck the selinux values into a pod annotation for
generation of the kube yaml. Then on play, we check annotations to see
if a value for the mount exists and apply it.

Podman 4.0 currently errors when you use network aliases for a network which
has dns disabled. Because the error happens on network setup this can

and also for network connect.

This matches what docker does. Also make sure the net aliases are also
shown when the container is stopped.
docker-compose uses this special alias entry to check if it is already
correctly connected to the network. [1]
Because we do not support static ips on network connect at the moment
calling disconnect && connect will loose the static ip.
