Anders F Björklund 336055fe3b Use url with scheme and path for the unix address
Shortcuts like unix:path and unix:/path do not work everywhere,
so make sure to use unix://path when quoting the url (or address)

Matt Heon ce736413b4 Ensure that we appropriately warn that TCP is insecure
`podman system service` + TCP is not a configuration we should be
recommending. There was already language about this in the
manpages, but it was not sufficient in explaining how bad of an
idea this is. Expand the manpage warnings, add a dedicated
heading so people notice, and add a warning every time the
service starts with a TCP URL that directs people to the manpage
to see that explanation.

Doug Rabson e3f2a97d1f cmd/podman/system: add API server support on FreeBSD
This adds the 'system service' command to the build on FreeBSD and
suppresses the call to servicereaper.Start which is only needed to
support slirp4netns on Linux. A stub for compat.StatsContainer is also
added - stats are still supported via the libpod.StatsContainer API
call.

system: add warning when running rootless on cgroupv1
when running rootless on cgroupv1, Podman+OCI runtime do not setup a
separate cgroup for the container.  Spawned containers will run in the
same cgroup as the podman system service process, thus will be killed
when the cgroup is destroyed, as it is the case when running as a
systemd service.

podman service: close duplicated /dev/null fd
Since we open /dev/null to set it as STDIN we can close it after the
dup2() call. Using defer is not good enough since this function will
never exit since the http server will block. This is not a problem but
it reduces the open fds from the service by one.

service: make move to sub-cgroup non fatal
if we are running in a container in the root cgroup, Podman tries to
move itself to a sub-cgroup.  This could be a problem in a setup where
the cgroups are not writeable, so just log a debug message and
continue, since anyway it is a best-effort operation.

podman service reaper
Add a new service reaper package. Podman currently does not reap all
child processes. The slirp4netns and rootlesskit processes are not
reaped. The is not a problem for local podman since the podman process
dies before the other processes and then init will reap them for us.

However with podman system service it is possible that the podman
process is still alive after slirp died. In this case podman has to reap
it or the slirp process will be a zombie until the service is stopped.

The service reaper will listen in an extra goroutine on SIGCHLD. Once it
receives this signal it will try to reap all pids that were added with
`AddPID()`. While I would like to just reap all children this is not
possible because many parts of the code use `os/exec` with `cmd.Wait()`.
If we reap before `cmd.Wait()` things can break, so reaping everything
is not an option.

With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules.  While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.

Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`.  The renaming of the imports
was done via `gomove` [1].

Valentin Rothberg 09dc701097 podman rmi: refactor logic
While this commit was initially meant to fix #5847, it has turned into a
bigger refactoring which I did not manage to break into smaller pieces:

 * Fix #5847 by refactoring the image-removal logic.

 * Make the api handler for image-removal use the ABI code. This way,
   both (i.e., ABI and Tunnel) end up using the same code.  Achieving
   this code share required to move some code around to prevent circular
   dependencies.

 * Everything in pkg/api (excluding pkg/api/types) must now only be
   accessed from code using `ABISupport`.

 * Avoid imports from entities on handlers to prevent circular
   dependencies.

 * Move `podman system service` logic into `cmd` to prevent circular
   dependencies - it depends on pkg/api.

 * Also remove the build header from infra/abi files.  It will otherwise
   confuse swagger and other tools; errors we cannot fix as go doesn't
   expose a build-tag env variable.
