* use safe xstrncpy() rather than strcpy()
* use sizeof() for static buffers rather than macro with real size
(this solution is more robust for future code changes)
* use xcalloc() to zeroize allocated memory

The format of /proc/net/udp was changed in
6c25449e1a32 ("net: udp: fix alignment problem in udp4_seq_show()").
This kind of change can be applied to /proc/net/tcp, too.

The loaded information is displayed at SOCKNETNS, SOCKSTATE,
SOCKTYPE, and/or UNIX.PATH columns of UNIX-STREAM and UNIX
typed sockets.

Files under /proc/net/ like unix, tcp, udp, etc. provides extra
information about sockets. To unitize these information in
lsfd, this change adds stub for loading the information form
/proc/net/* and attaching it to struct file presenting sockets.
