Most content proxy operations normalize remote RPC errors before
returning them, including stream receive errors from Walk and write
errors from the remote writer. remoteReaderAt.ReadAt was an outlier and
returned raw status errors from Read and Recv.
Callers that use content.ReadBlob through the proxy can then fail
errdefs checks, such as treating concurrent content deletion as
NotFound.
Convert non-EOF read stream errors with errgrpc.ToNative so ReaderAt
matches the rest of the content proxy while preserving io.EOF.

The remote content writer proxy already has the capability to break up
large files into multiple writes, but the current API doesn't recognize
when it's about to exceed the limits and attempts to send the data over
grpc in one message instead of breaking it into multiple messages.
This changes the behavior of `Write` to automatically break up the size
of the content based on the max send message size.

Uses the new github.com/containerd/errdefs/pkg module which is intended
to hold less stable utility functions separately from the stable
github.com/containerd/errdefs error types.
Includes temporary update to hcsshim until a release is cut there

Allow the api to stay at the same v1 go package name and keep using a
1.x version number. This indicates the API is still at 1.x and allows
sharing proto types with containerd 1.6 and 1.7 releases.
