Subject: tighten scope in libidu/, too

Mark with "extern" the symbols that belong that way.
Make the others static.
* libidu/dynvec.h (dv_fill):
* libidu/fnprint.c (cw_dlink):
* libidu/hash.h (qsort_cmp_t):
* libidu/idfile.h (io_func_t):
* libidu/scanners.c (lang_args_obstack, languages_0, languages_N):
(language_help_me, language_getopt, get_language):
(lang_args_index):
* libidu/walker.c (largest_member_file):
* maint.mk (extract_char, today):
* src/fid.c (long_options):
* src/fnid.c (cw_dlink):
* src/lid.c (cw_dlink):
* src/xtokid.c (cw_dlink):
