when the test binary starts, it detects whether it should run the container
initialization code or the execin initialization code based on the suppplied
arguments. The execin initialization code is taken from docker.
also added a sample test for execin process.

This removes the unsued namespace types from the namespace package
and simplifies getting the values for the namespaces.

This changes the namespace configuration on the config to include the
name of the namespace along with an optional path. This path is used to
point to a file of another namespace for the namespace so that it can be
joined in place of the empty, initialized namespace.

This document specifies the current container specification with all the
underlying setup and configuration that goes into making a container.
This is the v1 spec that is today but allows for flexability when we
introduce more features such as seccomp default profiles and more.

SELinux supports a call that tells the kernel, from this point onward
create content with this label. If you pass "", the kernel will
go back to the default.

Writing to this file within /sys is casuing some issues for
older kernels, specifically with 2.6.xx, where the write is failing
because /sys is becoming ro. We will continue to work on the 2.6 issues
but for the time being we cannot ship this with it enabled as it's
breaking all container runs.

Currently if we don't use --cpuset, the cpuset cgroup is not
created, it's bad if we want to modify cpuset config subsequently,
change the behavior to make it right.

There is no reason to have a special type returned from the cgroups
Apply function for getting the paths and cleanup. With access to the
paths we can just delete what we need.

Because we are using the paths that are created when we initially setup
cgroups for a container we no longer have to dynamically generates them
when a user requests stats. This allows us to fully use the fs stats
code without having system create it's paths.

Besides possible other problems 16bit UIDs might be disabled by the kernel
configuration on Linux for ARM (see CONFIG_UID16).

because `LoadContainerEnvironment` is already run, os.Environ() will return the
correct environment variables for the exec command (i.e. removed duplicated
envs, set HOME for user etc...)

This patch adds an os/user-like user lookup API, implemented in pure Go.
It also has some features not present in the standard library
implementation (such as group lookups).
