Allow creation and management of subcontainers through cgroupfs
directory syscalls. Also add a mechanism to specify a default root
container to start new jobs in.
This implements the filesystem support for subcontainers, but doesn't
implement hierarchical resource accounting or task migration.

Since cgroupfs.dir embedes cgroupfs.implStatFS, and dir.StatFS and
implStatFS.StatFS are identical, dir.StatFS is not needed.

Update/remove most syserror errors to linuxerr equivalents. For list
of removed errors, see //pkg/syserror/syserror.go.

Update all instances of the above errors to the faster linuxerr implementation.
With the temporary linuxerr.Equals(), no logical changes are made.

Remove three syserror entries duplicated in linuxerr. Because of the
linuxerr.Equals method, this is a mere change of return values from
syserror to linuxerr definitions.
Done with only these three errnos as CLs removing all grow to a significantly
large size.

The control files enumerating tasks and threads residing in cgroupfs
incorrectly locks cgroupfs.filesystem.tasksMu before
kernel.TaskSet.mu.
The contents of these control files are inherently racy anyways, so
use a snapshot of the tasks in the cgroup and drop tasksMu before
resolving pids/tids (which acquires TaskSet.mu).

Previously, registration was racy because we were publishing
hierarchies in the registry without fully initializing the underlying
filesystem. This led to concurrent mount(2)s discovering the partially
intialized filesystems and dropping the final refs on them which cause
them to be freed prematurely.

A skeleton implementation of cgroupfs. It supports trivial cpu and
memory controllers with no support for hierarchies.
