mkfs.bfs: fix memory leaks and weak code
- use size_t to store strlen() result
- init superblock with the default volume and fsname
- don't use strdup(), it's unnecessary as getopt_long() does not

- don't use memcpy() as we need to check string sizes
- restrict verbose output 6 bytes

mkfs.cramfs: reduce the synopsis to the standard, succinct form
The old synopsis was 1) incomplete (mentioning -h and -v, but not
-V and -E and -z, for example), and 2) overlong, being wider than
80 columns. So, change the synposis to what most other utilities
nowadays use: "<name> [options] <arguments>..." -- this makes it
much clearer what the two required arguments are.
Also, reshuffle the descriptions of the two arguments, to not hide
them among the options.
And remove the description of option -s, as listing an option that
does nothing is not helpful.
swapon: improve a translator hint, and remove a pointless one
The reference to "each entry below" made no sense, as that second
translator hint is not before a gettextized message and therefore
did not make it into the POT file. Gettextizing that message is
not useful as 1) there is nothing to translate, and 2) allowing
the translators to fiddle with the tabs is too complicated, and
3) the --summary output is deprecated anyway.

lsfd: add a dummy entry for UNIX socket having no peer to the IPC table
With recvfrom(2) and sendto(2), we can use a UNIX datagram socket at
server side without assigning a peer address with connect(2). Here, I
call such sockets one-way sockets.
The socket, opened with systemd as fd 227, is an example of one-way
socket (13465). It has 0 as "Peer Address:Port". From the side of
systemd process, there is no communication peers. However, the
sockets (35438 and 74792) opened with systemd-journal and bluetoothd
have the one-way socket (13465) as their communication peers.
We expect lsfd prints these connections if user specifies
-o+ENDPOINTS. This change and subsequent changes remove limitations in
this area.
In the early stage of lsfd process, lsfd collects information about
UNIX sockets on the system via unix-diag netlink. lsfd stores the
information to the IPC table. lsfd looks up the IPC table when
printing ENDPOINTS column.
With the original code, lsfd could not fill the ENDPOINTS columns
for sockets connecting to an one-way socket because lsfd did not
store one-way sockets to the IPC table.
With this change, lsfd can fill the ENDPOINTS columns for sockets
connecting to an one-way socket. The new code puts dummy entries for
the one-way sockets to the IPC table. The dummy entries help lsfd to
find the connections.
