+
+ Cons<->int and similar integer overflow fixes.

+ (LGLYPH_SET_CODE): Use INTEGER_TO_CONS.
+ * data.c (long_to_cons, cons_to_long): Remove.
+ (cons_to_unsigned, cons_to_signed): New functions.
+ These signal an error for invalid or out-of-range values.
+ * dired.c (Ffile_attributes): Use INTEGER_TO_CONS.
+ * fileio.c (Fset_visited_file_modtime): Use CONS_TO_INTEGER.

+ (x_get_foreign_selection, Fx_disown_selection_internal)
+ (Fx_get_atom_name, x_send_client_event): Use CONS_TO_INTEGER.
+ (lisp_data_to_selection_data): Use cons_to_unsigned.
+ (x_fill_property_data): Use cons_to_signed.
+ Report values out of range.
+
+ Check for buffer and string overflow more precisely.

+ if b->modtime has its maximal value.
+
+ * dired.c (Ffile_attributes): Don't assume EMACS_INT has >32 bits.
+
+ Don't assume time_t can fit into int.
+ * buffer.h (struct buffer.modtime): Now time_t, not int.
+ * fileio.c (Fvisited_file_modtime): No need for time_t cast now.
+ * undo.c (Fprimitive_undo): Use time_t, not int, for time_t value.
+
+ Minor fixes for signed vs unsigned integers.
+ * character.h (MAYBE_UNIFY_CHAR):
+ * charset.c (maybe_unify_char):
+ * keyboard.c (read_char, reorder_modifiers):
+ XINT -> XFASTINT, since the integer must be nonnegative.
+ * ftfont.c (ftfont_spec_pattern):
+ * keymap.c (access_keymap, silly_event_symbol_error):
+ XUINT -> XFASTINT, since the integer must be nonnegative.
+ (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
+ since it makes no difference and we prefer signed.
+ * keyboard.c (record_char): Use XUINT when all the neighbors do.
+ (access_keymap): NATNUMP -> INTEGERP, since the integer must be
+ nonnegative.

+ (display_prop_intangible_p): Reimplement to call
+ handle_display_spec instead of single_display_spec_intangible_p.

+ EMACS_INT.

Malloc failure behavior now depends on size of allocation.
* alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
(Fgnutls_boot): No need to check for memory allocation failure,
since xmalloc does that for us.

+ * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
+ * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
+ for hashes and hash indexes, instead of 'unsigned' and 'int'.
+ * alloc.c (allocate_vectorlike):
+ Check for overflow in vector size calculations.
+ * ccl.c (ccl_driver):
+ Check for overflow when converting EMACS_INT to int.
+ * fns.c, image.c: Remove unnecessary static decls that would otherwise
+ need to be updated by these changes.
+ * fns.c (make_hash_table, maybe_resize_hash_table):
+ Check for integer overflow with large hash tables.
+ (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):

+ Rewrite to use FIXNUM_BITS, as this simplifies things.
+ (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
+ Adjust signatures to match updated version of code.
+ (consing_since_gc): Now EMACS_INT, since a single hash table can
+ use more than INT_MAX bytes.
