[20.10] Revert "Ignore SIGURG on Linux."
This reverts commit 3c87f01b18.

This commit introduced two regressions;

- spurious "Unsupported signal: <nil>. Discarding."
- docker start --attach hanging if the container does not
  have a TTY attached

Reverting for now, while we dug deeper into what's causing
the regression.

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

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]

Recheck the container's state to avoid attach block.

Shukui Yang f9dc3337f9 Recheck the container's state to avoid attach block.
If use docker attach command to attach to a stop container, it will return
"You cannot attach to a stopped container" error, it's ok, but when
attach to a running container, it(docker attach) use inspect to check
the container's state, if it pass the state check on the client side,
and then the container is stopped, docker attach command still attach to
the container and not exit.
