Brian Goff e1a7517514 Fix `docker start` blocking on signal handling
We refactorted `ForwardAllSignals` so it blocks but did not update the
call in `start` to call it in a goroutine.

Brian Goff fff164c22e Ignore SIGURG on Linux.
In go1.14+, SIGURG is used by the runtime to handle preemtable system
calls.
In practice this signal caught *frequently*.

Mark checkpoint feature as Linux-only, and homogenize error messages
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

Kir Kolyshkin 395957155f cli/command/container: don't leak context
Switch from x/net/context to context made "go vet" see the previously
unseen errors:

> cli/command/container/start.go:57::error: the cancelFun function is
> not used on all paths (possible context leak) (vet)
> cli/command/container/start.go:63::error: this return statement may be
> reached without using the cancelFun var defined on line 57 (vet)

> cli/command/container/run.go:159::error: the cancelFun function is not
> used on all paths (possible context leak) (vet)
> cli/command/container/run.go:164::error: this return statement may be
> reached without using the cancelFun var defined on line 159 (vet)

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.

Kir Kolyshkin 6f8070deb2 Switch from x/net/context to context
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]
