Converting cast expressions to macros that are retargetted

to C++ style casts when compiling as C++.

* lib.h (strip_qual, convert, coerce): New casting macros.
(TAG_MASK, tag, type, wli_noex, auto_str, static_str,
litptr, num_fast, chr, lit_noex, nil, nao): Use cast macros.

* arith.c (mul, isqrt_fixnum, bit): Use cast macros.

* configure (INT_PTR_MAX): Define using cast macro.

* debug.c (debug_init): Use cast macro.

* eval.c (do_eval, expand_macro, reg_op, reg_mac, eval_init):
Use cast macros.

* filter.c (filter_init): Use cast macro.

* gc.c (more, mark_obj, in_heap, mark, sweep_one, unmark): Use
cast macros.

* hash.c (hash_double, equal_hash, eql_hash, hash_equal_op,
hash_hash_op, hash_print_op, hash_mark, make_hash, make_similar_hash,
copy_hash, gethash_c, gethash, gethash_f, gethash_n, remhash,
hash_count, get_hash_userdata, set_hash_userdata, hash_iter_destroy,
hash_iter_mark, hash_begin, hash_uni, hash_diff, hash_isec): Use
cast macros.

* lib.c (code2type, chk_malloc, chk_malloc_gc_more, chk_calloc,
chk_realloc, chk_strdup, num, c_num, string, mkstring, mkustring,
upcase_str, downcase_str, string_extend, sub_str, cat_str, trim_str,
c_chr, vector, vec_set_length, copy_vec, sub_vec, cat_vec,
cobj_print_op, obj_init): Likewise.

* match.c (do_match_line, hv_trampoline, match_files, dir_tables_init):
Likewise.

* parser.l (grammar): Likewise.

* parser.y (parse): Likewise.

* rand.c (make_state, make_random_state, random_fixnum, random):
Likewise.

* regex.c (CHAR_SET_L2_LO, CHAR_SET_L2_HI, CHAR_SET_L1_LO,
CHAR_SET_L1_HI, CHAR_SET_L0_LO, CHAR_SET_L0_HI, L0_full, L0_fill_range,
L1_full, L1_fill_range, L1_contains, L1_free, L2_full, L2_fill_range,
L2_contains, L2_free, L3_fill_range, L3_contains, L3_free,
char_set_create, char_set_cobj_destroy, nfa_state_accept,
nfa_state_empty, nfa_state_single, nfa_state_wild, nfa_state_set,
