And use it only in local tooling that is forwarding the pseudoterminal
master. That way runC no longer has an opinion on the onlcr setting
for folks who are creating a terminal and detaching. They'll use
--console-socket and can setup the pseudoterminal however they like
without runC having an opinion. With this commit, the only cases
where runC still has applies SaneTerminal is when *it* is the process
consuming the master descriptor.

This maybe a nice extra but it adds complication to the usecase. The
contract is listen on the socket and you get an fd to the pty master and
that is that.

This is a proof-of-concept for the --console-socket API. It just acts as
a dumb input-output copy process (nowhere near as good as the internal
runC one since it doesn't handle console resizes or signals). It also
provides a test-friendly mode that will be used in the bats integration
tests.
This patch is part of the console rewrite patchset.

This allows a user to send a signal to all the processes in the
container within a single atomic action to avoid new processes being
forked off before the signal can be sent.
This is basically taking functionality that we already use being
`delete` and exposing it ok the `kill` command by adding a flag.
