or arbitrary window as argument. Update doc-strings.
(Fminibuffer_window): Move up in code.
(Fwindow_minibuffer_p): Move up in code and simplify.
(Fset_frame_selected_window): Move here from frame.c. Marginal
rewrite.

Use INTEGER_TO_CONS.
(x_handle_selection_request, x_handle_selection_clear)
(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.

Report values out of range.
* buffer.h (BUF_BYTES_MAX): New macro.
* lisp.h (STRING_BYTES_MAX): New macro.
* alloc.c (Fmake_string):
* character.c (string_escape_byte8):
* coding.c (coding_alloc_by_realloc):
* doprnt.c (doprnt):
* editfns.c (Fformat):
* eval.c (verror):
Use STRING_BYTES_MAX, not MOST_POSITIVE_FIXNUM,
since they may not be the same number.
* editfns.c (Finsert_char):
* fileio.c (Finsert_file_contents):
Likewise for BUF_BYTES_MAX.
(slurp_file): Switch from int to ptrdiff_t.
All uses changed.
(slurp_file): Check that file size fits in both size_t (for
malloc) and ptrdiff_t (for sanity and safety).
* 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.
* character.h (MAYBE_UNIFY_CHAR):
* charset.c (maybe_unify_char):

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.
* gtkutil.c (xg_get_default_scrollbar_width): New function.
* gtkutil.h: Declare xg_get_default_scrollbar_width.
* xfns.c (x_set_scroll_bar_default_width): If USE_GTK, get
