These opts either inherit the parent cgroup device.list or append the
default unix devices like /dev/null /dev/random so that the container
has access.

This function is analogous to `regexp.MustCompile` and can simplify production
of a `Platform` from a hard-coded strings, e.g. for global variable
initialisation.

Switches the client/server direction of the shim-log pipe on Windows so
that the shim is the listener. This allows the containerd client to
reconnect as needed to the log streams.

The man page namespace is global, so in order to avoid colliding with
other man pages named "config.toml" rename ours to be more descriptive.
This also helps with discoverability (now tab-completion of 'man
containerd<tab>' will return the config man page), as well as making it
much cleaner from the perspective of distributions that want to package
containerd.

A fifo on unix or named pipe on Windows will be provided to the shim.
It can be located inside the `cwd` of the shim named "log".
The shims can use the existing `github.com/containerd/containerd/log` package to log debug messages.
Messages will automatically be output in the containerd's daemon logs with the correct fiels and runtime set.

mount thing to avoid hitting one page argument buffer in linux kernel
mount.
