month validity; signal an error if it isn't. (Bug#40217)

have 'margin' count in the height of the tab bar to avoid that
tab bar and internal border are drawn on top of each other.
* lisp/eshell/em-dirs.el (eshell-dirs-initialize): Add INSIDE_EMACS
variable to buffer-local value of eshell-variable-aliases-alist.
(eshell-inside-emacs): Add new constant used for INSIDE_EMACS.

test for the INSIDE_EMACS variable.
* etc/NEWS: Announce changes.
* lisp/htmlfontify.el (hfy-default-header): declare the character
encoding for the generated HTML file. This helps browsers display
UTF-8 characters like the copyright symbol correctly.
(hfy-sprintf-stylesheet): apply the default style to all of the text
consistently, so that unstyled bits (which are not wrapped in span
tags and are directly part of the surrounding pre tag's "innerHTML")
have a look consistent with the rest of the document.

(vc-dir-mark-registered-files)
(vc-dir-mark-unregistered-files): New commands.

(vc-dir-menu-map): Add menu entries for
vc-dir-mark-registered-files and vc-dir-mark-unregistered-files.
Separate values for box line width and height and allow both to be
negative which makes the visual width and height of the boxed string
unchanged (Bug#13011).
* doc/lispref/display.texi (Face Attributes): Modify :box attribute
description to reflect the new possibilities.
* lisp/cus-face.el (custom-face-attributes): Set box attribute to get
two integer to set vertical and horizontal width and modify pre-filter
to accept dotted list of two int as valid box attribute.
* src/dispextern.h (face): Use two int for box horizontal and vertical
line width.
* src/nsfont.m (nsfont_draw): Use new face attributes.
* src/nsterm.m (ns_draw_box, ns_draw_relief): Support separated
horizontal and vertical box line width.
(ns_dumpglyphs_box_or_relief, ns_maybe_dumpglyphs_background)

(x_draw_composite_glyph_string_foreground)
(x_draw_glyphless_glyph_string_foreground, x_draw_glyph_string_box)
(x_draw_image_foreground, x_draw_image_relief)
(w32_draw_image_foreground_1, x_draw_image_glyph_string): Use new face
attributes.
* src/xfaces.c (Sinternal_set_lisp_face_attribute, realize_x_face):
Accept box attribute as a list of two ints.
* src/xdisp.c (estimate_mode_line_height, produce_image_glyph)
(produce_xwidget_glyph, x_produce_glyphs): Use new face attributes.
* src/xterm.c (x_draw_box_rect, x_draw_relief_rect): Support separated
horizontal and vertical box line width.
(x_draw_glyph_string_background, x_draw_glyph_string_foreground)
(x_draw_composite_glyph_string_foreground)
(x_draw_glyphless_glyph_string_foreground, x_draw_glyph_string_box)
(x_draw_image_foreground, x_draw_image_relief, x_draw_image_foreground_1)
(x_draw_image_glyph_string): Use new face attributes.
* 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.

(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.
Suggested by Eric Michael Timmons <etimmons@mit.edu>.
* lisp/fileloop.el (fileloop-initialize-replace): Save the
match-beginning position in a variable instead of the buffer's point.
The point may be changed by the time perform-replace is called, e.g.,
due to switch-to-buffer-preserve-window-point.
* test/lisp/net/tramp-tests.el (tramp-test29-start-file-process)
(tramp-test30-make-process, tramp-test33-environment-variables):
Expect failure on hydra.nixos.org, since March 29 Tramp cache changes.
* lisp/minibuffer.el (minibuffer-completion-help): Run
display-completion-list in the original buffer mainbuf
to allow completion-setup-function set completion-reference-buffer to it.
* lisp/progmodes/project.el (project--find-regexp-in-files):
Signal user-error when passed an empty list of files.
* lisp/progmodes/xref.el (xref-matches-in-files):
Make sure FILES is not empty.
* lisp/imenu.el (imenu-update-menubar): No longer accept a list of length 1 as
being sufficient evidence for a nested list structure. Instead, additionally
check whether or not certain elements are atoms.
* 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.
