This was problematic when minibuffer-follows-selected-frame was non-nil.
Introduce a new parameter DONT-SET-FRAME to set-window-configuration.
* doc/lispref/windows.texi (Window Configurations): Describe the new &optional
parameter to set-window-configuration.

and document it in the doc string. At the final do_switch_frame operation,
restore the original frame when DONT-SET-FRAME is non-nil.

argument is a cons.
* doc/emacs/mini.texi (Basic Minibuffer): Add an entry for
minibuffer-follows-selected-frame.

is_minibuffer.
* src/minibuf.c (minibuf_follows_frame): New function which ignores local and
let-bound values of minibuffer-follows-selected-frame.
(choose_minibuf_frame): Reformulate this function to reuse a minibuffer window
where possible, and to ensure no other frame has its minibuffer current, but
only when `minibuffer-follows-selected-frame'.
(move_minibuffer_onto_frame): New function.
(live_minibuffer_p): New function.
(Fminibufferp): Add a new &optional parameter LIVE. Reformulate, possibly
calling live_minibuffer_p.
(read_minibuf): move the incrementation of minibuf_level to before the call of
choose_minibuf_frame. Empty the miniwindows of frames without an active
minibuffer, rather than of all but the current frame.

Rename these DEFVAR_BOOL variables to avoid the initial "V"
that wrongly suggests that they are Lisp_Object variables.
All uses changed.
Avoid problems if GC occurs while initializing a vector.
Problem with Fdelete reported by Pip Cet in:
https://lists.gnu.org/r/emacs-devel/2020-08/msg00313.html

* src/nsfns.m (ns_set_internal_border_width):
* src/xfns.c (x_set_internal_border_width):
Using check_int_nonnegative means these functions no longer
incorrectly reject negative bignums; they treat them as 0,
just like negative fixnums.
If a position argument to get-byte etc. is an out-of-range integer,
treat it the same regardless of whether it is a fixnum or a bignum.

Use it instead of CHECK_FIXNUM_COERCE_MARKER, so that
the code is simpler and treats bignums consistently with fixnums.
* src/buffer.h (CHECK_FIXNUM_COERCE_MARKER): Define here
rather than in lisp.h, and reimplement in terms of fix_position
so that it treats bignums consistently with fixnums.

(minibuffer-local-map): Remap recenter/scroll symbols to their
minibuffer wrappers: recenter-top-bottom to minibuffer-recenter-top-bottom.
* src/window.c (Fother_window_for_scrolling): Use 'lambda' value for
MINIBUF arg of Fnext_window, so minibuffer-scroll-other-window and
minibuffer-scroll-other-window-down doesn't try to scroll the
minibuffer window.
* src/window.c (coordinates_in_window): Fix conditions for
coordinates being on the window's header line when that
window also displays a tab-line. (Bug#37807)

pseudo windows changed height so the top margin has to be
adjusted.
* src/window.c (Fset_window_configuration): Call
adjust_frame_size with inhibit 4.
This mostly changes http: to https: in URLs. It also updates
some URLs that have moved, removes some URLs that no longer
work, recommends against using procmail (procmail.org no
longer works), and removes some mentions of the
no-longer-existing Gmane, LPF and VTW.
It doesn't update all URLs, just the ones I had time for.

be 'bottom' to show a horizontal scroll bar on mini windows.
* lisp/window.el (window-min-pixel-height): For mini windows the
minimum height is one line.
(window--min-size-1): Use value returned by
'window-min-pixel-height' when dealing with mini windows.
(window--resize-mini-window): Try to handle horizontal scroll
bars and size restrictions more accurately.
(window--state-put-2): Handle persistence of scroll bar
settings.

'resize_frame_windows' calls.
* src/window.c (set_window_buffer): Don't override WINDOW's
scroll bar and fringe settings when marked as persistent.
(resize_frame_windows): Drop fourth argument PIXELWISE - SIZE
is always specified in terms of pixels. Try to handle height
of mini windows more accurately.
(grow_mini_window, shrink_mini_window): Use body height of
mini window when calculating expected height change. Take
horizontal scroll bars into account.
(struct saved_window): Two new members to handle persistence
of window fringes and scroll bars.
(Fset_window_configuration, save_window_save): Handle
persistence of fringes and scroll bars.
(set_window_fringes, set_window_scroll_bars): New arguments
PERSISTENT. Make dimension checks more accurate.
(Fset_window_fringes): New argument PERSISTENT.
(Fwindow_fringes, Fwindow_scroll_bars): Add PERSISTENT to
return values.
(Fset_window_scroll_bars): New argument PERSISTENT. In
doc-string mention that 'bottom' must be specified to get a
horizontal scroll bar in mini windows.
(compare_window_configurations): Add checks for persistence of
fringes and scroll bars.

scroll bar when its type is specified as 'bottom'.
* etc/NEWS: Mention new options for 'set-window-fringes' and
'set-window-scroll-bars'.
This is a minor patch to remove some fixnum restrictions.
Many more such patches are needed, but one thing at a time.
* doc/emacs/custom.texi (Examining): Update fill-column example.
* src/buffer.c (fill-column, left-margin, tab-width)
(buffer-saved-size, left-margin-width, right-margin-width)
(left-fringe-width, right-fringe-width, scroll-bar-width)
(scroll-bar-height, buffer-display-count):
Allow any integer; do not restrict to fixnums.
* src/character.h (SANE_TAB_WIDTH): Do not assume tab_width
is a nonnegative fixnum.
(sanitize_tab_width): Take a Lisp_Object integer, not an
EMACS_INT. Only use changed.
* src/data.c (store_symval_forwarding): Remove unnecessary
SYMBOLP since the predicate (e.g., Qintegerp) is always a
symbol (leave the test in as an eassert). Avoid assignments
inside if-conditions.
* src/fileio.c (Fdo_auto_save): Do not assume
buffer-saved-size is a fixnum. Avoid undefined behavior
on EMACS_INT overflow by multiplying a fixnum by at most 4,
not by at most 13.
* src/window.c (set_window_buffer): When buffer-display-count
is too large for a fixnum, make it a bignum.
* src/xdisp.c (FILL_COLUMN_INDICATOR_NEEDED): Remove macro, ...
(fill_column_indicator_column): ... replacing with this new function.
All uses changed. The function is a bit pickier, to prevent
problems with non-character fixnums and columns out of range
for int, and to remove the assumption that integers are in
fixnum range.
(append_space_for_newline, extend_face_to_end_of_line):
Avoid undefined behavior with signed integer overflow.
Simplify.
Problem reported by Keith David Bershatsky in:
https://lists.gnu.org/r/emacs-devel/2019-04/msg00259.html
Solution suggested by Stefan Monnier in:
https://lists.gnu.org/r/emacs-devel/2019-04/msg00282.html
* src/buffer.h (BUFFER_LISP_SIZE): Simplify by using PSEUDOVECSIZE.
(BUFFER_REST_SIZE): Simplify by using VECSIZE and BUFFER_LISP_SIZE.
* src/lisp.h (PSEUDOVECSIZE): Base it on the last Lisp field,
not the first non-Lisp field. All callers changed. Callers
without Lisp fields changed to use ALLOCATE_PLAIN_PSEUDOVECTOR.
(ALLOCATE_PLAIN_PSEUDOVECTOR): New macro.
* doc/lispref/windows.texi (Window Start and End):
* src/window.c (Fset_window_start): Document that reliable
setting of a window start position requires to adjust point to
be visible. (Bug#34038)
* src/window.c (Fset_window_margins, Fset_window_fringes)
(Fset_window_scroll_bars): In doc-strings tell that a window
must be large enough to accommodate fringes, sroll bars and
margins of the desired size.
* doc/lispref/display.texi (Fringe Size/Pos, Scroll Bars)
(Display Margins): Tell that windows must be large enough to
accommodate fringes, sroll bars and margins of the desired
size.
* src/frame.c (resize_mini_frames): New variable.
* src/window.c (resize_mini_window_apply): New function.
(grow_mini_window, shrink_mini_window): Remove PIXELWISE
argument. Call resize_mini_window_apply to apply changes.
(Fresize_mini_window_internal): Call resize_mini_window_apply
to apply changes.
(Qwindow__resize_mini_frame): New symbol.
* src/window.h (grow_mini_window, shrink_mini_window): Adjust
external declarations.
* src/xdisp.c (resize_mini_window): For minibuffer-only frames
call 'window--resize-mini-frame' if resize_mini_frames is
non-nil. Offload parts of logic to grow_mini_window and
shrink_mini_window which are now called without the PIXELWISE
argument.
(Vresize_mini_windows): Mention 'resize-mini-frames' in
doc-string.
* lisp/cus-start.el (resize-mini-frames): Add customization
support.
* lisp/window.el (window--resize-mini-window): Simplify code.
(window--resize-mini-frame): New function.
* doc/lispref/minibuf.texi (Minibuffer Windows): Describe new
option 'resize-mini-frames'.
* etc/NEWS: Mention new option 'resize-mini-frames'.
* doc/lispref/windows.texi (Window Hooks): Revise description
of window change functions. Add documentation for
'window-state-change-hook' and window state change flag.
* etc/NEWS: Update entry for window change functions.
* src/frame.c (Fframe_window_state_change)
(Fset_frame_window_state_change): New functions.
* src/frame.h (struct frame): New boolean window_state_change.
(FRAME_WINDOW_STATE_CHANGE): New macro.
* src/window.c (window_change_record_frames): New static
boolean.
(window_change_record_frame): Remove function - code moved to
window_change_record.
(window_change_record): Record frame changes here taking
window_change_record_frames into account.
(run_window_change_functions_1): Set window_change_record_frames
whenever we run one of our hooks.
(run_window_change_functions): Run hooks also when
FRAME_WINDOW_STATE_CHANGE has been set. Run
Vwindow_state_change_hook. Leave decision whether to record
changes for all frames to window_change_record.
(Vwindow_state_change_functions): Update doc-string.
(Vwindow_state_change_hook): New normal hook.
The main new thing here is that C code can now say
‘list (a, b, c, d, e, f)’ instead of
‘listn (CONSTYPE_HEAP, 6, a, b, c, d, e, f)’,
thus relieving callers of the responsibility of counting
arguments (plus, the code feels more like Lisp). The old
list1 ... list5 functions remain, as they’re probably a bit
faster for small lists.
* src/alloc.c (cons_listn, pure_listn): New functions.
(listn): Omit enum argument.
All callers changed to use either new ‘list’ or ‘pure_list’ macros.

* src/nsterm.m (performDragOperation:):
* src/pdumper.c (Fpdumper_stats):
* src/w32.c (init_environment):
Prefer list1, list2, etc. to open-coding them.
* src/font.c (font_list_entities):
Parenthesize to avoid expanding new ‘list’ macro.
* src/gtkutil.c (GETSETUP): Rename from MAKE_FLOAT_PAGE_SETUP
to get lines to fit. Move outside the ‘list’ call, since it’s
now a macro.
* src/keymap.c (Fmake_keymap): Simplify.
* src/lisp.h (list, pure_list): New macros.
(list1i): New function.
Formerly they were fixnums, which led to problems when dealing
with values that might not fit on 32-bit platforms, such as
string-chars-consed or floats_consed. 64-bit counters should
be good enough for these (for a while, anyway...).

(window_scroll_pixel_based, window_scroll_line_based):
Use it to avoid signed integer overflow.

functions before updating the display so changes induced by
these functions can get caught by redisplay (Bug#34138).

hack. All uses changed.

since my static-vs-extern checking hack relies on it.

Add a new portable dumper as an alternative to unexec. Use it by default.
