cddf85d256 Remove all_buffers and the associated next field of buffers
* src/alloc.c (enum mem_type): Remove MEM_TYPE_BUFFER.
(allocate_buffer): Allocate like any other pseudovector.
Don't register on `all_buffers` any more.
(live_buffer_holding, live_buffer_p): Delete functions.
(mark_maybe_object, valid_lisp_object_p): Don't pay attention to
MEM_TYPE_BUFFER any more.
(garbage_collect): Only compact the live buffers.
(mark_buffer): Mark the undo_list of dead buffers here.
(mark_object): Buffers are normal pseudovectors now.
(sweep_buffers): Don't do the actual sweep here, just cleanup the
markers and only for live buffers.

* src/buffer.c (all_buffers): Remove variable.
(Fkill_buffer): Don't check indirect dead buffers.
Set the undo_list before we remove ourselves from the list of live buffers.
(Fbuffer_swap_text, Fset_buffer_multibyte): Don't check indirect dead
buffers.
(init_buffer_once): Don't set `all_buffers`.
(init_buffer): Don't map new memory for dead buffers.

* src/buffer.h (struct buffer): Remove `next` field.
(FOR_EACH_BUFFER): Remove macro.

* src/pdumper.c (dump_buffer): Don't dump the `next` field.

ced7852046 Avoid assertion violation at startup in pdumped Emacs
* src/buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Remove the
assertion that ensured all buffers in pdumped Emacs have non-NULL
pointer to buffer text.  That was false when Emacs was pdumped
with killed buffer(s) in the all_buffers linked list.  See
https://lists.gnu.org/archive/html/emacs-devel/2020-03/msg00800.html
for more details.

de00a933e4 Treat out-of-range positions consistently
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.
* src/buffer.c (fix_position): New function.
* src/buffer.c (validate_region):
* src/character.c (Fget_byte):
* src/coding.c (Ffind_coding_systems_region_internal)
(Fcheck_coding_systems_region):
* src/composite.c (Ffind_composition_internal):
* src/editfns.c (Fposition_bytes, Fchar_after, Fchar_before)
(Finsert_buffer_substring, Fcompare_buffer_substrings)
(Fnarrow_to_region):
* src/fns.c (Fsecure_hash_algorithms):
* src/font.c (Finternal_char_font, Ffont_at):
* src/fringe.c (Ffringe_bitmaps_at_pos):
* src/search.c (search_command):
* src/textprop.c (get_char_property_and_overlay):
* src/window.c (Fpos_visible_in_window_p):
* src/xdisp.c (Fwindow_text_pixel_size):
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.
* src/lisp.h (CHECK_FIXNUM_COERCE_MARKER): Move to buffer.h.
* src/textprop.c (validate_interval_range): Signal with original
bounds rather than modified ones.

This allows control of the minimum size of a masked image under
which the box cursor becomes hollow.
* buffer.c (cursor-type): Add commentary about (box . SIZE)
'cursor-type'.
* xdisp.c (get_specified_cursor_type): Check for 'cursor-type'
of the form (box . SIZE).
(get_window_cursor_type): Check masked image size for
(box . SIZE) 'cursor-type'.

* doc/emacs/display.texi (Cursor Display):
* doc/emacs/display.texi (Cursor Parameters): Add description
of (box . SIZE) 'cursor-type'.

* etc/NEWS: Mention the new (box . SIZE) 'cursor-type'.
