Have adjust_frame_size pass native frame sizes to backends
instead of text sizes. Expand frame size history management.
Drop PIXELWISE argument from change_frame_size and convert
native to text sizes only when calling adjust_frame_size. Use
convention in arguments that -1 instead of 0 means that no size
change is required. When adjusting frame sizes pick up delayed
size changes (Bug#46827).
* lisp/frame.el (frame-notice-user-settings, make-frame): Don't
set frame size history.
(frame--size-history): Rewrite doc-string. Handle new formats

when it either differs from F's current pixel sizes or F's
previously queued sizes. Inject frame_size_history_extra call
when queuing. Adopt convention that for queued sizes -1 means
that no size change is required. Convert from native to text
sizes when calling adjust_frame_size.

also in change_frame_size_1 calls.

negative values for new sizes mean no change. Pick up delayed
size changes from F's new_width and new_height slots
(Bug#46827). Call set_window_size_hook with native instead of
text sizes. Do not sanitize window sizes any more. Call
frame_size_history_adjust instead of frame_size_history_add.
Always set F's resized_p slot to true.

explicit sizes and the corresponding parameter are passed to
adjust_frame_size. Remove frame_size_history_add call.
(gui_figure_window_size): Drop last two arguments. Simplify
assignment of initial size. Set new_height and new_width slots
to -1. Use adjust_frame_size to set sizes instead of returning
them to caller.

are now built on-the-fly. Also drop some menu bar related
symbols in favor of Qmenu_bar_lines.

FRAME_INNER_WIDTH and FRAME_INNER_HEIGHT.
(gui_figure_window_size): Drop last two arguments from
extern.

and HEIGHT. Consult delayed_size_change to handle case where
WIDTH and HEIGHT do not match F's new_width and new_height
values. Call change_frame_size with native sizes and without
PIXELWISE argument. Instead of frame_size_history_add call
frame_size_history_extra.

fix adjust_frame_size call accordingly. Instead of
frame_size_history_add call frame_size_history_extra.

SET_FRAME_HEIGHT, the adjust_frame_size in
gui_figure_window_size did that already.

its processing; WIDTH and HEIGHT represent native pixel sizes
now. Call change_frame_size with native sizes. Remove call to
frame_size_history_add.

in gui_figure_window_size call. Do not SET_FRAME_WIDTH and

Formerly they were fixnums, which led to problems when dealing

string-chars-consed or floats_consed. 64-bit counters should

* src/term.c (produce_glyphs): Correct TAB width only when
line_number_produced_p flag is set.
Latest Terminfo introduces terminal definitions that support direct
color mode. The "Co"/"colors" capability is set to 0x1000000 on these
terminals and Emacs is already compatible with them.
However, if used Terminfo library hasn't been compiled with 32-bit
value support, "Co"/"colors" is truncated to 0x7fff. In this case
direct color mode support can be detected from the "RGB" capability
flag.
There are some minor problems if the color count isn't corrected from
0x7fff. First eight standard colors defined in xterm-standard-colors
are shown correctly. However, their RGB values match the terminal
settings, not the RGB values defined in xterm-standard-colors. Bright
versions of these colors are shown incorrectly. They are interpreted
as pixels #000008 - #000015, which are very dark shades of blue.
* src/term.c (init_tty): Force terminal color count to 0x1000000 if
"RGB" capability is present.
* src/tparam.h: Define prototype for tigetflag. (Bug#30308)
* doc/misc/efaq.texi (Colors on a TTY): Add information about direct
mode terminals supported by Terminfo.
This fixes some URLs I omitted from my previous pass,
notably those in lists.gnu.org. Although lists.gnu.org
does not yet support TLS 1.1, TLS 1.0 is better than nothing.

Problem reported by Richard Stallman (Bug#17406).
Based on fix suggested by Eli Zaretskii (Bug#28279#16).

Use only safe accessors, to avoid crash when C-g C-g in GC.
