archive, cio, cmd, linux: use buffer pools 
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.

Add an option to prevent putting the shim in a new mount namespace 
This is needed for users on kernel older than 3.18 so they can avoid EBUSY
errors when trying to unlink, rename or remove a mountpoint that is present in
a shim namespace.

194b6e4f06 Start of day configuration of shim debug setting 
This makes it possible to enable shim debug by adding the following to
`config.toml`:

    [plugins.linux]
    shim_debug = true

I moved the debug setting from the `client.Config struct` to an argument to
`client.WithStart` since this is the only place it would be used.

990536f2cc Move shim protos into linux pkg 
This moves the shim's API and protos out of the containerd services
package and into the linux runtime package. This is because the shim is
an implementation detail of the linux runtime that we have and it is not
a containerd user facing api.
