Sigterm handling

lxc-init: use SIGKILL after alarm timeout

see comment for details.
Signed-off-by: Tycho Andersen <tycho@tycho.ws>

For the ->execute() case, we want to make sure the application dies when
SIGHUP is received. The next patch will ignore SIGHUP in the lxc monitor,
because tasks inside the container send SIGHUP to init to have it reload
its config sometimes, and we don't want to do that with init.lxc, since it
might actually kill the container if it forwards SIGHUP to the child and
the child can't handle it.

d76e3e1a inadvertently switched the alarm timeout from sigterm to sigkill.
We really want sigkill here, so let's bring it back.

hooks: change the semantic of NVIDIA_VISIBLE_DEVICES=""

With LXC, you can override the value of an environment variable to
null, but you can't unset an existing variable.

The NVIDIA hook was previously activated when NVIDIA_VISIBLE_DEVICES
was set to null. As a result, it was not possible to disable the hook
by overriding the environment variable in the configuration.

The hook can now be disabled by setting NVIDIA_VISIBLE_DEVICES to
null or to the new special value "void".

Unpriv fixups

Signed-off-by: Tycho Andersen <tycho@tycho.ws>

In particular, if we are already in a user namespace we are unprivileged,
and doing things like moving the physical nics back to the host netns won't
work. Let's do the same thing LXD does if euid == 0: inspect
/proc/self/uid_map and see what that says.
Signed-off-by: Tycho Andersen <tycho@tycho.ws>

Consider the case where we're running in a user namespace but in the host's
mount ns with the host's filesystem (something like
lxc-usernsexec ... lxc-execute ...), in this case, we'll be euid 0, but we
can't actually write to /run. Let's improve this locking check to make sure
we can actually write to /run before we decide to actually use it as our
locking dir.

[cgfsng] show wrong errno

lxc_cgroup_set_data: h = get_hierarchy(controller);
if h is NULL, now errno is old, it donot set new one.
And then,
cgfsng_setup_limits:

    if (lxc_cgroup_set_data(cg->subsystem, cg->value, d)) {
		if (do_devices && (errno == EACCES ||
			errno == EPERM)) {
			WARN("Error setting %s to %s for %s",
				cg->subsystem, cg->value,
				d->name);
			continue;
		}
		SYSERROR("Error setting %s to %s for
			 %s",
			 cg->subsystem, cg->value,
			 d->name);
		goto out;
	}

SYSERROR will show old errno, make me confused.
