autodev: adapt to changes in Linux 4.18 
Starting with commit
55956b59df33 ("vfs: Allow userns root to call mknod on owned filesystems.")
Linux will allow mknod() in user namespaces for userns root if CAP_MKNOD is
available.
However, these device nodes are useless since

static struct super_block *alloc_super(struct file_system_type *type, int flags,
                                       struct user_namespace *user_ns)
{
        /* <snip> */

        if (s->s_user_ns != &init_user_ns)
                s->s_iflags |= SB_I_NODEV;

        /* <snip> */
}

will set the SB_I_NODEV flag on the filesystem. When a device node created in
non-init userns is open()ed the call chain will hit:

bool may_open_dev(const struct path *path)
{
        return !(path->mnt->mnt_flags & MNT_NODEV) &&
                !(path->mnt->mnt_sb->s_iflags & SB_I_NODEV);
}

which will cause an EPERM because the device node is located on an fs
owned by non-init-userns and thus doesn't grant access to device nodes due to
SB_I_NODEV.

The solution is straightforward. Unless you're real root you should bind-mount
device nodes.

e5adb2b559 clear ONLCR flag for container pty 
now container pty output log, use \r\n as a newline flag.
This is a windows type, so we need to change it. By clear
ONLCR can reach it.

log: add lxc_log_strerror_r macro 
Let's ensure that we always use the thread-safe strerror_r() function and add
an approriate macro.
Additionally, define SYS*() macros for all log levels. They will use the new
macro and ensure thread-safe retrieval of errno values.
