This renames the runtime interface to PlatformRuntime to denote the
layer at which the runtime is being abstracted. This should be used to
abstract different platforms that vary greatly and do not have full
compat with OCI based binary runtimes.

We move from having our own generated version of the googleapis files to
an upstream version that is present in gogo. As part of this, we update
the protobuf package to 1.0 and make some corrections for slight
differences in the generated code.
The impact of this change is very low.

This changes the Windows runtime to use the snapshotter and differ
created layers, and updates the ctr commands to use the snapshotter and differ.

Because of a side-effect import, we have the possibility of pulling in
several unnecessary packages that are used by the plugin and not at
runtime to implement protobuf structures. Setting these imports to
`weak` prevents this from happening, reducing the total import set,
reducing memory usage and binary size.

To avoid importing all of grpc when consuming events, the types of
events have been split in to a separate package. This should allow a
reduction in memory usage in cases where a package is consuming events
but not using the gprc service directly.

Since these are registered and the interface is what matters, these
Service types do not need to be exported.

After several requests for information about platform support,
configuration introspection and feature switches, we now have a solution
that should work in all these use cases. The Introspection API hooks
into the plugin subsystem registration process. During registration,
plugins declare several pieces of information, allowing clients to
discover the cababilities and support that a containerd instance
provides, including whether or not it loaded with an error.
To allow symmetrical error reporting, the `google/rpc.Status` protobuf
definitions have been brought in from the googleapis project.
Unfortunately, we had to generate these in place to match our protobuf
system.
Once we like this design, we can add an implementation to integrate it
directly with the plugin system.
Enjoy!

This prevents `task.Wait()` to return an error if it is called before the task
is started.

When we generate protobufs, descriptors outlining all messages and
services are merged into a single file that can be used to identify
unexpected changes to the API that may affect stability. We follow a
similar process to Go's stability guarantees using the protobuf
descriptors to identify changes before they become a problem.
Please see README.md for details.

This changes Wait() from returning an error whenever you call wait on a
stopped process/task to returning the exit status from the process.
This also adds the exit status to the Status() call on a process/task so
that a user can Wait(), check status, then cancel the wait to avoid
races in event handling.

In the course of setting out to add filters and address some cleanup, it
was found that we had a few problems in the events subsystem that needed
addressing before moving forward.
The biggest change was to move to the more standard terminology of
publish and subscribe. We make this terminology change across the Go
interface and the GRPC API, making the behavior more familier. The
previous system was very context-oriented, which is no longer required.
With this, we've removed a large amount of dead and unneeded code. Event
transactions, context storage and the concept of `Poster` is gone. This
has been replaced in most places with a `Publisher`, which matches the
actual usage throughout the codebase, removing the need for helpers.
There are still some questions around the way events are handled in the
shim. Right now, we've preserved some of the existing bugs which may
require more extensive changes to resolve correctly.

This removes the RuntimeEvent super proto with enums into separate
runtime event protos to be inline with the other events that are output
by containerd.
This also renames the runtime events into Task* events.
