Create a new session key ring '_ses' for every container. This avoids sharing
the key structure with the process that created the container and the
container inherits from.
This patch fixes it init and exec.

GetMounts is very cpu-expensive. I'll change other funcs in this package
to reuse code from GetCgroupMounts later.

It's never used and not needed. Our pipe is created with
syscall.SOCK_CLOEXEC, so pipe will be closed once container
process executed successfully, parent process will read EOF
and continue. If container process got error before executed,
we'll write procError to sync with parent.

By adding detach to runc the container process is the only thing running
on the system is the containers process.
This allows better usage of memeory and no runc process being long
lived. With this addition you also need a delete command because the
detached container will not be able to remove state and the left over
cgroups directories.

We don't need a CreatedTime method on the container because it's not
part of the interface and can be received via the state. We also do not
need to call it CreateTime because the type of this field is time.Time
so we know its time.

Add some further (not critical, since Docker does this already)
validation to systemd slice names, to make sure users don't get cryptic
errors.

Marshall the raw objects for the sync pipes so that no new line chars
are left behind in the pipe causing errors.

This leaves out the internal conversions as we may need to consider
docker backward compatibility for those changes.

Rather than using '/' to denote hierarchy in slice names, systemd uses
'-' in an odd way. This results in runC incorrectly assuming that
certain kernel features are missing (and using inconsistent paths for
the cgroups not supported by systemd), because the "subsystem path" used
is not the one that systemd has created. Fix all of this by properly
expanding slice names.
