Fixes#1499
This traps any Accept() errors on server shutdown so that it exits
cleanly.
It also changes gracefulstop to stop on the grpc server as the daemon
will not shutdown if there are connected clients.

This is a workaround because official images were pushed with multi-arch
support recently and the current Pull code is not accounting for this.

To allow for updating extensions without collisions, we have moved to
using a map type that can be explicitly selected via the field path for
updates. This ensures that multiple parties can operate on their
extensions without stepping on each other's toes or incurring an
inordinate number of round trips.

Matching support is now implemented in the platforms package. The
`Parse` function now returns a matcher object that can be used to
match OCI platform specifications. We define this as an interface to
allow the creation of helpers oriented around platform selection.

For supporting selection of images and runtimes in the containerized
world, there is thin support for selecting objects by platform. This
package defines a syntax to display to users that can express specific
platforms in addition to wild cards for matching platforms.
The plan is to extend this to provide support for parsing flag
arguments and displaying platform types for images. This package will
also provide a configurable matcher to allow match of platforms against
arbitrary targets, invariant to the Go compilation.
The internals are based the OCI Image Spec model.
This changeset is being submitted for feedback on the approach before
this gets larger. Specifically, review the unit tests and raise any
concerns.

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.

ref: #1464
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.

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.
