This enables containers to mount fuse filesystems per default. The mount
is designed to be safe. Hence, it can be enabled per default in
common.conf. It will lead to a cleaner boot for some unprivileged
systemd-based containers.

This resolves the case where /proc/sysrq-trigger doesn't exist by simply
ignoring any mount failure on ENOENT. With the current mount list, this
will always result in a safe environment (typically the read-only
underlay).

Because we now create the ttys from inside the container, we had to
add an apparmor rule for start-container to bind-mount /dev/pts/** -> /dev/tty*/.
However that's not sufficient if the container sets lxc.ttydir, in
which case we need to support mounting onto files in subdirs of /dev.

We were trying to be smart and use whatever the last part of
the container's rootfs path was.  However for block devices
that doesn't make much sense.  I.e. if lxc.rootfs = /dev/md-1,
chances are that /var/lib/lxc/c1/md-1 does not exist.

So always use the $lxcpath/$lxcname/rootfs, and if it does
not exist, try to create it.

With this, 'lxc-clone -s -o c1 -n c2' where c1 has an lvm backend
is fixed.  See https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1414771Signed-off-by: Serge Hallyn <serge.hallyn@ubuntu.com>

Lxc has always created the ptys for use by console and ttys early
on from the monitor process.  This has some advantages, but also
has disadvantages, namely (1) container ptys counting against the
max ptys for the host, and (2) not having a /dev/pts/N in the
container to pass to getty.  (2) was not a problem for us historically
because we bind-mounted the host's /dev/pts/N onto a /dev/ttyN in
the container.  However, systemd hardocdes a check for container_ttys
that the path have 'pts/' in it.  If it were only for (2) I'd have
opted for a systemd patch to check the device major number, but (1)
made it worth moving the openpty to the container namespace.

So this patch moves the tty creation into the task which becomes
the container init.  It then passes the fds for the opened ptys
back to the monitor over a unix socketpair (for use by lxc-console).
The /dev/console is still created in the monitor process, so that
it can for instance be used by lxc.logfd.

So now if you have a foreground container with lxc.tty = 4, you
should end up with one host /dev/pts entry per container rather than 5.

And lxc-console now works with systemd containers.

Note that if the container init mounts its own devpts over the
one mounted by lxc, the tty /dev/pts/n will be hidden.  This is ok
since it's only systemd that needs it, and systemd won't do that.
