This patch adds annotations to mark the checkpoint commands as Linux only, which
hides them if the daemon is running a non-matching operating-system type;
Before:
docker
Usage: docker COMMAND
A self-sufficient runtime for containers
...
Management Commands:
config Manage Docker configs
container Manage containers
image Manage images
After:
docker
Usage: docker COMMAND
A self-sufficient runtime for containers
...
Management Commands:
checkpoint Manage checkpoints
config Manage Docker configs
container Manage containers
image Manage images
This change also prints errors when attempting to use checkpoint commands or
flags if the feature is not supported by the Daemon's operating system;
$ docker checkpoint --help
docker checkpoint is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows
$ docker checkpoint create --help
docker checkpoint create is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows
$ docker checkpoint ls --help
docker checkpoint ls is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows
$ docker checkpoint rm --help
docker checkpoint rm is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows
$ docker container start --checkpoint=foo mycontainer
"--checkpoint" requires the Docker daemon to run on linux, but the Docker daemon is running on windows
$ docker container start --checkpoint-dir=/foo/bar mycontainer
"--checkpoint-dir" requires the Docker daemon to run on linux, but the Docker daemon is running on windows

Switch from x/net/context to context made "go vet" see the previously
unseen errors:

Do call the cancel function.
Note we might end up calling it twice which is fine as long as I can see
from the Go 1.10 source code.

Since go 1.7, "context" is a standard package. Since go 1.9,
x/net/context merely provides some types aliased to those in
the standard context package.
The changes were performed by the following script:
for f in $(git ls-files \*.go | grep -v ^vendor/); do
sed -i 's|golang.org/x/net/context|context|' $f
goimports -w $f
for i in 1 2; do
awk '/^$/ {e=1; next;}
/\t"context"$/ {e=0;}
{if (e) {print ""; e=0}; print;}' < $f > $f.new && \
mv $f.new $f
goimports -w $f
done
done
[v2: do awk/goimports fixup twice]

It has been refactored to a hijackedIOStreamer type which has several
methods which are used to prepare input and handle streaming the input
and output separately.

The docker/client package was updated to support the updated Container
Wait API functionality. The run and start commands have been updated to
use the new wait features.

Whitelist some existing offenders, and use a high limit for now.
This limit should decrese over time.
