Update unicode tables to Unicode 14.0.0; initial charsets immutable
* 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.
