This field allows a client to store specialized information in the
container metadata rather than having to store this itself and keep
the data in sync with containerd.

This tries to solve issues with races around process state. First it
adds the process mutex around the state call so that any state changes,
deletions, etc will be handled in order.
Second, for IsNoExist errors from the runtime, return a stopped state if
a process has been removed from the underlying OCI runtime but not from
the shim yet. This shouldn't happen with the lock from above but its
hare to verify this issue.
Third, handle shim disconnections and return an ErrNotFound.
Forth, don't abort returning all tasks if one task is unable to return
its state.

This adds an option for the cgroups monitor to include container metrics
in the prometheus output. We will have to use the plugin to emit oom
events via the events service but when the `no_prom` setting is set for
the plugin container metrics will not be included in the prom output.

Here is list of improvement:
- Add 2 intermediate full samples of code that can be compiled and ran
- Link to Runc.md page for runc installation
- Fix typo at the "Task Wait and Start" section
- Fix missing commands to run sample code at the getting stated guide
- Explicitly State go 1.8.x or above and link back to golang install page

Prevent unpack failures due to id collision or the need to
wait for another process to finish unpacking. Always attempt
to unpack a layer and handle collisions on commit. Commit
collisions are easily handled as it could be considered the
same as a successful unpack.

Ensure that the descriptors are re-generated on the CI and block merges
that don't include updates. We also enable the `check-protos` check as
part of this process. The installation process for protobufs has been
fixed to support protobuild.

This will be made readonly by runc based on spec.Root.Readonly (which we
already set correctly) but defering until then gives runc the chance to make
any missing mount points as it processes the spec.Mount array.
This is necessary because many container images lack mount points for things
like the /etc/hosts which we want to overbind. This is not noticed with e.g.
Docker because it automatically creates an additional layer containing those.
This is something we may want to do here as well eventually but for now using a
writeable snapshot is both necessary and sufficient.
The same does not apply to the sandbox since we never modify its rootfs or want
to mount anything in it etc, add a comment to clarify.
Fixes#220.

Corrects compile on FreeBSD by handling the lack of ENODATA on FreeBSD.
Since continuity project has already handled this, using their const is
simpler than separating a few extra files in containerd/containerd.

Content commit is updated to take in a context, allowing
content to be committed within the same context the writer
was in. This is useful when commit may be able to use more
context to complete the action rather than creating its own.
An example of this being useful is for the metadata implementation
of content, having a context allows tests to fully create
content in one database transaction by making use of the context.
