Update lxc.containers.conf(5) in Japanese

Update for commit 767bd70aSigned-off-by: KATOH Yasufumi <karma@jazz.email.ne.jp>

Bad sgml/man translation

When calling "man lxc.container.conf", an internal "man" keyword is displayed :

$ man lxc.container.conf
[...]
lxc.mount.entry
              Specify a mount point corresponding to a line in the fstab format.  Moreover lxc supports mount  propagation,  such  as
              rslave  or  rprivate, and adds three additional mount options.  optional don't fail if mount does not work.  create=dir
              or create=file to create dir (or file) when the point will be mounted.  relative source path is taken to be relative to
              the mounted container root. For instance,

dev/null proc/kcore none bind,relative 0 0
              .fi     <-----------------------------------UNEXPECTED KEYWORD !!!!

The problem seems to come from the missing blanks before "dev/null proc/kcore none bind,relative 0 0"

Moreover, for homogeneity purposes, it is better to use the "programlisting" tag used in the rest of the text instead of  "screen".

start: handle setting pdeath signal in new pidns

In the usual case the child runs in a separate pid namespace. So far we haven't
been able to reliably set the pdeath signal. When we set the pdeath signal we
need to verify that we haven't lost a race whereby we have been orphaned and
though we have set a pdeath signal it won't help us since, well, the parent is
dead.
We were able to correctly handle this case when we were in the same pidns since
getppid() will return a valid pid. When we are in a separate pidns 0 will be
returned since the parent doesn't exist in our pidns.
A while back, while Jann and I were discussing other things he came up with a
nifty idea: simply pass an fd for the parent's status file and check the
"State:" field. This is the implementation of that idea.

utils: Copying source filename to avoid missing info

Some applications use information from LOOP_GET_STATUS64. The file
associated with loop device is pointed inside structure field
`lo_file_name`. The current code is setting up a loop device without
this information. A legacy example of code checking this is cryptsetup:

    static char *_ioctl_backing_file(const char *loop)
    {
        struct loop_info64 lo64 = {0};
        int loop_fd;

        loop_fd = open(loop, O_RDONLY);
        if (loop_fd < 0)
            return NULL;

        if (ioctl(loop_fd, LOOP_GET_STATUS64, &lo64) < 0) {
            close(loop_fd);
            return NULL;
        }

        lo64.lo_file_name[LO_NAME_SIZE-2] = '*';
        lo64.lo_file_name[LO_NAME_SIZE-1] = 0;

        close(loop_fd);
        return strdup((char*)lo64.lo_file_name);
    }

It will return an empty string because lo_file_name was not set.
