Add a waitgroup to wait for the io.Copy of stdout/err to finish before
existing runc. The problem happens more in exec because it is really
fast and the pipe has data buffered but not yet read after the process
has already exited.

newSignalHandler needs to be called before the process is started, otherwise when
the process exits quickly the SIGCHLD is recieved (and ignored) before the
handler is set up. When this happens the reaper never runs, the
process becomes a zombie, and the exit code isn't returned to the user.

Closes#532
This requires the container id to always be passed to all runc commands
as arg one on the cli. This was the result of the last OCI meeting and
how operations work with the spec.

This flag allows systems that are running runc to allocate tty's that
they own and provide to the container.

Fix state transitions for inprocess
Because the tests use libcontainer in process between the various states
we need to ensure that that usecase works as well as the out of process
one.

I deleted possibility to specify config file from commands for now.
Until we decide how it'll be done. Also I changed runc spec interface to
write config files instead of output them.

Without this, multiple runc containers can accidentally share the same cgroup(s)
(and change each other's limits), when runc is invoked from the same directory
(i.e.: same cwd on multiple runc executions).
After these changes, each runc container will run on its own cgroup(s). Before,
the only workaround was to invoke runc from an unique (temporary?) cwd for each
container.
Common cgroup configuration (and hierarchical limits) can be set by having
multiple runc containers share the same cgroup parent, which is the cgroup of
the process executing runc.

There was previously a memory issue in the signal handler that showed up
when using restore. This has been fixed, therefore, restore can use the
signal handler.

This removes the Processes slice and only allows for one process of the
container. It also renames TTY to Terminal for a cross platform
meaning.
