* libguile/srfi-14.i.c: Update from Unicode 14.0.0.
* libguile/unidata_to_charset.pl (compute): Write arrays as static const
data, to avoid polluting the namespace and to avoid adding these to the
GC root set.
* libguile/srfi-14.c (SCM_CODEPOINT_F_IMMUTABLE): New flag.
(scm_charset_is_immutable): New internal predicate.
(SCM_VALIDATE_MUTABLE_CHARSET): New internal validator.
(cs_full_ranges, cs_full_ranges_len): Re-express as separate ranges and
len, because the ranges pointer in scm_t_char_set is mutable.
(scm_char_set_unfold_x, scm_list_to_char_set_x)
(scm_string_to_char_set_x, scm_char_set_filter_x)
(scm_i_ucs_range_to_char_set, scm_char_set_adjoin_x)
(scm_char_set_delete_x, scm_char_set_complement_x)
(scm_char_set_unfold_x, scm_char_set_intersection_x)
(scm_char_set_difference_x, scm_char_set_xor_x): Require mutable
charsets.
(define_charset): Add immutable flag.
(scm_init_srfi_14): Adapt initial charset definitions.
