        * glib.h:
        * gutils.h: added a bunch of utility/wrapper functions:
        g_basename(), g_getcwd(), g_get_user_name(), g_get_real_name(),
        g_get_home_dir(), g_get_tmp_dir(), g_get_prgname() and g_set_prgname().

        * gutils.c: removed all g_str* functions.
        * gstrfuncs.c: moved the bunch g_str* functions from gutils.c in this
        place. this file shall never include <stdlib.h> to avoid clashes for
        some of the g_str* functions on some OSes.
