After review, there are cases where having common requirements for
namespaces and identifiers creates contention between applications. One
example is that it is nice to have namespaces comply with domain name
requirement, but that does not allow underscores, which are required for
certain identifiers.
The namespaces validation has been reverted to be in line with RFC 1035.
Existing identifiers has been modified to allow simply alpha-numeric
identifiers, while limiting adjacent separators.
We may follow up tweaks for the identifier charset but this split should
remove the hard decisions.

We hope that containerd supports any OCI compliant runtime, and not only
runc.
This patch fixes all the error messages to not be completely runc
specific and change the initProcess structure to have its runtime
pointer be called 'runtime' and not 'runc'

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.

Update go-runc to master with portability fixes.
Subreaper only exists on Linux, and only Linux runs the shim in a
mount namespace.
With these changes the shim compiles on Darwin, which means the
whole build compiles without errors now.

Because of go interface unpacking we need to only set the interface on
the opts when we actually have a socket.

This reuses the exiting shim code and services to let containerd run as
the reaper for all container processes without the use of a shim.
