(Fx_create_frame): Call x_set_scroll_bar_default_width instead
of GetSystemMetrics.

WINDOW_SCROLL_BAR_AREA_WIDTH.
(x_new_font): Make it correspond to changes in xterm.c.
src/search.c (newline_cache_on_off, find_newline): In indirect
buffers, use the newline cache of the base buffer.
src/insdel.c (invalidate_buffer_caches): If BUF is an indirect
buffer, invalidate the caches of its base buffer.
src/indent.c (width_run_cache_on_off, compute_motion): In indirect
buffers, use the width-run cache of the base buffer.
src/xdisp.c (redisplay_window): When the window displays an indirect
buffer, and the character widths in the display table have
changed, invalidate the width-run cache of the corresponding base
buffer.
src/fileio.c (Finsert_file_contents): When invalidating the newline
cache, consider the case of inserting into indirect buffer.
src/bidi.c (bidi_paragraph_cache_on_off, bidi_find_paragraph_start):
In indirect buffers, use the paragraph cache of the base buffer.
configure.ac (canonical, C_SWITCH_SYSTEM): Support a 64-bit
MinGW64 build on MS-Windows.
nt/inc/ms-w32.h (sys_kill): Fix prototype.
src/w32term.c (w32_initialize): Use LCID and LOWORD.
src/w32proc.c (create_child): Use pid_t for 5th argument.
(IsValidLocale): Don't provide prototype for MinGW64.
(Fw32_get_valid_keyboard_layouts, Fw32_get_keyboard_layout)
(Fw32_set_keyboard_layout): Use HKL and HIWORD/LOWORD.
src/w32heap.c (allocate_heap) [_WIN64]: Use "ull", not "i64", which
MinGW64 doesn't support.
src/lisp.h (EMACS_INT) [_WIN64]: Define for the MinGW64 build.
src/w32.c (set_named_security_info): New function.
(acl_set_file): Fall back on set_named_security_info if
set_file_security fails. Fixes rare failures in backups.
(g_b_init_set_named_security_info_w)
(g_b_init_set_named_security_info_a): New static variables.
(globals_of_w32): Initialize them to zero.
(set_named_security_info): Set them to non-zero if the
corresponding API is available.
(SetNamedSecurityInfoW_Proc, SetNamedSecurityInfoA_Proc): New
function typedefs.
* gtkutil.c (x_wm_set_size_hint): Have size hints respect value
of frame_resize_pixelwise.
* widget.c (pixel_to_text_size): New function.
(update_wm_hints): Have size hints respect value of
frame_resize_pixelwise.
(EmacsFrameResize): Alway process resize requests pixelwise.
* window.c (grow_mini_window): Make sure mini window is at least
one line tall.
* xdisp.c (display_menu_bar): Make sure menubar extends till
right end of frame.
* xfns.c (x_set_menu_bar_lines): Resize frame windows pixelwise.
(x_set_tool_bar_lines): Calculate pixelwise.
* xterm.c (x_wm_set_size_hint): Have size hints respect value of
frame_resize_pixelwise.
* doc/lispref/files.texi (Changing Files): Document this.
* etc/NEWS: Document this.
* src/fileio.c (realmask): Now a static var, not a local.
(barf_or_query_if_file_exists): New arg KNOWN_TO_EXIST.
Remove arg STATPTR. All uses changed.
(Fcopy_file): Do not alter permissions of existing destinations,
unless PRESERVE-PERMISSIONS (renamed from
PRESERVE-EXTENDED-ATTRIBUTES) is non-nil.
Avoid race when testing for existing destinations and for
when input and output files are the same.
If changing the group fails, adjust both default and
preserved permissions so that access is not granted to the
wrong group.
(Fset_default_file_modes, init_fileio): Update realmask.
(Fdefault_file_modes): Use realmask instead of calling umask.
