Given these same exact functions are both now available in
opencontainers/runc (libcontainer/system) package, and we only use the
`SetSubreaper` today from the shim, there seems to be no reason for
duplication.

To avoid buffer bloat in long running processes, we try to use buffer
pools where possible. This is meant to address shim memory usage issues,
but may not be the root cause.

This improves the exec support so that they can run along with the
normal stress tests. You don't have to pick exec stres or container
stress. They both run at the same time and report the different values.

After comtemplation, the complexity of the logging module system
outweighs its usefulness. This changeset removes the system and restores
lighter weight code paths. As a concession, we can always provide more
context when necessary to log messages to understand them without having
to fork the context for a certain set of calls.

Ensure whiteout is not pointing to the current directory
or parent directory before removing. Protects against invalid
removal of the parent or current directory.
Add whiteout related tar tests using manufactured tar conditions.

Chown would normally be a no-op if uid/gid match, however some
filesystems (e.g. NFS) will return EPERM.

Because tasks may be deleted while listing containers, we need to ignore
errors from state requests that are due to a closed error. All of these
get mapped to ErrNotFound, which can be used to filter the entries.
There may be a better fix that does a better job of keeping track of the
intended state of a backend task. The current condition of assuming that
a closed client is a shutdown task may be too naive.

This allows other packages and plugins to easily exec things without
racing with the reaper.
The reaper is mostly needed in the shim but can be removed in containerd
in favor of the `exec.Cmd` apis
