        * configure.in:
        * testglib.c:
        * gstrfuncs.c:
        * glib.h: added g_strlcat() and g_strlcpy() wrappers, supplied by
        David Wheeler <dwheeler@ida.org>:

        * glib.h, gstrfuncs.c: added g_strlcpy and g_strlcat to support
          safe manipulation of fixed-length string buffers.
          These functions were originally developed by Todd Miller to simplify
          development of security-related programs, and
          are available on many (but not all) Unix-like systems,
          including OpenBSD, FreeBSD, and Solaris.  See
          ftp://ftp.openbsd.org/pub/OpenBSD/src/lib/libc/string/strlcpy.3
          and http://www.openbsd.org/security.html.
          If there's a strlcpy/strlcat on the system, it's called, otherwise
          an implementation is provided.

        * testglib.c: Added tests for g_strlcpy, g_strlcat.
