The github.com/containerd/containerd/log package was moved to a separate
module, which will also be used by upcoming (patch) releases of containerd.
This patch moves our own uses of the package to use the new module.

With a full attach, each attach was leaking 4 goroutines.
This updates attach to use errgroup instead of the hodge-podge of
waitgroups and channels.
In addition, the detach event was never being sent.

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

The promise package represents a simple enough concurrency pattern that
replicating it in place is sufficient. To end the propagation of this
package, it has been removed and the uses have been inlined.
While this code could likely be refactored to be simpler without the
package, the changes have been minimized to reduce the possibility of
defects. Someone else may want to do further refactoring to remove
closures and reduce the number of goroutines in use.

The use of pools.Copy avoids io.Copy's internal buffer allocation.
This commit replaces io.Copy with pools.Copy to avoid the allocation of
buffers in io.Copy.

This patch adds the untilRemoved option to the ContainerWait API which
allows the client to wait until the container is not only exited but
also removed.
This patch also adds some more CLI integration tests for waiting for a
created container and waiting with the new --until-removed flag.

Apply container wait changes to API 1.30
The set of changes to the containerWait API missed the cut for the
Docker 17.05 release (API version 1.29). This patch bumps the version
checks to use 1.30 instead.
This patch also makes a minor update to a testfile which was added to
the builder/dockerfile package.

Use router.WithCancel in the containerWait handler
This handler previously added this functionality manually but now uses
the existing wrapper which does it for us.

Add WaitCondition constants to api/types/container

Address more ContainerWait review comments
- Update ContainerWait backend interface to not return pointer values
for container.StateStatus type.
- Updated container state's Wait() method comments to clarify that a
context MUST be used for cancelling the request, setting timeouts,
and to avoid goroutine leaks.
- Removed unnecessary buffering when making channels in the client's
ContainerWait methods.
- Renamed result and error channels in client's ContainerWait methods
to clarify that only a single result or error value would be sent
on the channel.

`copyEscapable` is a copy/paste of io.Copy with some added handling for
checking for the attach escape sequence.
This removes the copy/paste and uses `io.Copy` directly. To be able to
do this, it now implements an `io.Reader` which proxies to the main
reader but looks for the escape sequence.

This cleans up attach a little bit, and moves it out of the container
package.
Really `AttachStream` is a method on `*stream.Config`, so moved if from
a package level function to one bound to `Config`.
In addition, uses a config struct rather than passing around tons and
tons of arguments.

`StreamConfig` carries with it a dep on libcontainerd, which is used by
other projects, but libcontainerd doesn't compile on all platforms, so
move it to `github.com/docker/docker/container/stream`
