Initial cgroupfs support for subcontainers
Allow creation and management of subcontainers through cgroupfs
directory syscalls. Also add a mechanism to specify a default root

This implements the filesystem support for subcontainers, but doesn't
implement hierarchical resource accounting or task migration.
