move the logic for joining existing namespaces down to the rootless
package. In main_local we still retrieve the list of conmon pid files
and use it from the rootless package.
In addition, create a temporary user namespace for reading these
files, as the unprivileged user might not have enough privileges for
reading the conmon pid file, for example when running with a different
uidmap and root in the container is different than the rootless user.

it creates a namespace where the current UID:GID on the host is mapped
to the same UID:GID in the container.

When we supercede low-priority mounts and volumes (image volumes,
and volumes sourced from --volumes-from) with higher-priority
ones (the --volume and --mount flags), we always replaced
lower-priority mounts of the same type (e.g. a user mount to
/tmp/test1 would supercede a volumes-from mount to the same
destination). However, we did not supercede the opposite type - a
named volume from image volumes at /tmp/test1 would be allowed to
remain and create a conflict, preventing container creation.
Solve this by destroying opposite types before merging (we can't
do it in the same loop, as then named volumes, which go second,
might trample changes made by mounts).

when doing any sort of attach to a container, a sigwinch is sent
followed by a resize event. this is fine for the local client but when
doing things over the varlink, the first sigwinch is wiped out by the
immediate resize event and is therefore lost. by making the channel
buffered, both events are processed after the varlink connection is
established.

add a shortcut for joining immediately the namespace so we don't need
to re-exec Podman.
With the pause process simplificaton, we can now attempt to join the
namespaces as soon as Podman starts (and before the Go runtime kicks
in), so that we don't need to re-exec and use just one process.

use a pause process to keep the user and mount namespace alive.
The pause process is created immediately on reload, and all successive
Podman processes will refer to it for joining the user&mount
namespace.
This solves all the race conditions we had on joining the correct
namespaces using the conmon processes.
As a fallback if the join fails for any reason (e.g. the pause process
was killed), then we try to join the running containers as we were
doing before.

As part of this, rework the number of workers used by various
Podman tasks to match original behavior - need an explicit
fallthrough in the switch statement for that block to work as
expected.
Also, trivial change to Podman cleanup to work on initialized
