When spec file contains duplicated namespaces, e.g.
specs: specs.Spec{
Linux: &specs.Linux{
Namespaces: []specs.Namespace{
{
Type: "pid",
},
{
Type: "pid",
Path: "/proc/1/ns/pid",
},
},
},
}
runc should report malformed spec instead of using latest one by
default, because this spec could be quite confusing.

Alternative of #895 , part of #892
The intension of current behavior if to create cgroup in
parent cgroup of current process, but we did this in a
wrong way, we used devices cgroup path of current process
as the default parent path for all subsystems, this is
wrong because we don't always have the same cgroup path
for all subsystems.

Setting classid of net_cls cgroup failed:
ERRO[0000] process_linux.go:291: setting cgroup config for ready process caused "failed to write 𐀁 to net_cls.classid: write /sys/fs/cgroup/net_cls,net_prio/user.slice/abc/net_cls.classid: invalid argument"
process_linux.go:291: setting cgroup config for ready process caused "failed to write 𐀁 to net_cls.classid: write /sys/fs/cgroup/net_cls,net_prio/user.slice/abc/net_cls.classid: invalid argument"
The spec has classid as a *uint32, the libcontainer configs should match the type.

This adds an `--no-new-keyring` flag to run and create so that a new
session keyring is not created for the container and the calling
processes keyring is inherited.

This adds a `--no-pivot` cli flag to runc so that a container's rootfs
can be located ontop of ramdisk/tmpfs and not fail because you cannot
pivot root.
This should be a cli flag and not part of the spec because this is a
detail of the host/runtime environment and not an attribute of a
container.

Users of libcontainer other than runc may also require parsing and
converting specification configuration files.
Since runc cannot be imported, move the relevant functions and
definitions to a separate package, libcontainer/specconv.
