fdcc2257df libpod: use OCI idmappings for mounts
Now that the OCI runtime specs have support for idmapped mounts, let's
use them instead of relying on the custom annotation in crun.

Also add the mechanism to specify the mapping to use.  Pick the same
format used by crun so it won't be a breaking change for users that
are already using it.

5a2405ae1b Don't mount /dev/tty* inside privileged containers running systemd
According to https://systemd.io/CONTAINER_INTERFACE/, systemd will try take
control over /dev/ttyN if exported, which can cause conflicts with the host's tty
in privileged containers. Thus we will not expose these to privileged containers
in systemd mode, as this is a bad idea according to systemd's maintainers.

Additionally, this commit adds a bats regression test to check that no /dev/ttyN
are present in a privileged container in systemd mode

This fixes https://github.com/containers/podman/issues/15878

d968f3fe09 Replace deprecated ioutil
Package `io/ioutil` was deprecated in golang 1.16, preventing podman from
building under Fedora 37.  Fortunately, functionality identical
replacements are provided by the packages `io` and `os`.  Replace all
usage of all `io/ioutil` symbols with appropriate substitutions
according to the golang docs.

dc8fdb46c5 label.Relabel third option is shared not recurse
There is no option in Selinux labeling to only relabel the top level of
a directory. The option is to either label the path shared or not
shared. Changing to make sure future engineers do not assume that
recurse can work.

2c63b8439b Fix stutters
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.

a3aecf0f26 libpod: Factor out setting volume atime to container_internal_linux.go
It turns out that field names in syscall.Stat_t are platform-specific.
An alternative to this could change fixVolumePermissions to use
unix.Lstat since unix.Stat_t uses the same mmember name for Atim on both
Linux and FreeBSD.
