Without this, multiple runc containers can accidentally share the same cgroup(s)
(and change each other's limits), when runc is invoked from the same directory
(i.e.: same cwd on multiple runc executions).
After these changes, each runc container will run on its own cgroup(s). Before,
the only workaround was to invoke runc from an unique (temporary?) cwd for each
container.
Common cgroup configuration (and hierarchical limits) can be set by having
multiple runc containers share the same cgroup parent, which is the cgroup of
the process executing runc.

And allow cgroup mount take flags from user configs.
As we show ro in the recommendation, so hard-coded
read-only flag should be removed.

This fixes a bug where IDMapping.From was mapped to IDMap.ContainerID
and IDMapping.To was mapped to IDMap.HostID, while the old spec docs
were:
// From is the uid/gid of the host user or group.
From int32 `json:"from"`
// To is the uid/gid of the container's user or group.
To int32 `json:"to"`
The new IDMapping field names make the expected mapping more obvious
(HostID -> HostID and ContainerID -> ContainerID ;).
Should compile now without errors but changes needed to be added for each system so it actually works.
main_unsupported.go is a new file with all the unsupported commands

This removes the Processes slice and only allows for one process of the
container. It also renames TTY to Terminal for a cross platform
meaning.
