This attempts to future-proof Emacs a bit against possible glibc
changes, by having Emacs use <malloc.h> declarations rather than
coding them up by hand. Problem noted by Florian Weimer in:
https://sourceware.org/ml/libc-alpha/2016-01/msg00777.html
Implement this mainly by moving malloc.h-related functions from
emacs.c (which does not include <malloc.h>) to alloc.c (which does).
* src/alloc.c (my_heap_start) [DOUG_LEA_MALLOC || GNU_LINUX]:
New function.
The remaining changes to this file apply only if DOUG_LEA_MALLOC.
(alloc_unexec_pre, alloc_unexec_post): New functions.
(malloc_initialize_hook): Use my_heap_start and alloc_unexec_post.
(__MALLOC_HOOK_VOLATILE): New macro, if not already defined.
(__malloc_initialize_hook): Use it.
(malloc_state_ptr, malloc_initialize_hook, __malloc_initialize_hook):
Move here from ...
* src/emacs.c: ... here.
(malloc_get_state, malloc_set_state): Remove extern decls.
(my_heap_start) [DOUG_LEA_MALLOC || GNU_LINUX]: Remove static var.
All uses changed to similarly-named new function.
(Fdump_emacs): Use new functions alloc_unexec_pre, alloc_unexec_post.
* src/lisp.h (my_heap_start, alloc_unexec_pre, alloc_unexec_post):
New decls.
* src/ftfont.c (ftfont_shape_by_flt): Fix previous change. Access the
second glyph only when there are enough glyphs.
(cherry picked from commit 9835757013)
* lisp/language/hebrew.el (hebrew-shape-gstring): If the font backend
supports rendering of combining characters, call
font-shape-gstring.
* src/font.c (Ffont_get): Handle `combining-capability' property.
(syms_of_font): New symbol ":combining-capability'.
* src/font.h (struct font_driver): New member combining_capability.
* src/ftfont.c: Include "category.h".
(ftfont_driver): Initialize combining_capability to
ftfont_combining_capability.
(ftfont_shape_by_flt): If OTF is null, try to find a suitable
FLT in advance.
(ftfont_combining_capability): New function.
(cherry picked from commit 536f48e9a2)
When in fullscreen mode, `[screen visibleFrame]' sometimes
includes, sometimes excludes the menu bar. This could cause
a frame to be placed too low when in fullscreen mode.
* src/nsterm.m (ns_menu_bar_should_be_hidden): Trace.
(constrain_frame_rect): New parameter, isFullscreen, when true don't
query the height of the menu bar.
(ns_constrain_all_frames): Pass `false' (isFullscreen) to
`constrain_frame_rect'.
([EmacsView initFrameFromEmacs:]): Trace.
([EmacsView isFullscreen]): Trace.
([EmacsWindow constrainFrameRect:toScreen:]): Pass fullscreen
state to `constrain_frame_rect'.
(dir-locals-file): Revert to its original fixed value.
(dir-locals-file-2): New const.
(dir-locals--all-files): Don't use `file-name-all-completions'.
Instead, just check for the 2 dir-locals files and return a list
of the ones that exit (if any).
* etc/NEWS: Document the change.
* doc/emacs/custom.texi (Directory Variables): Document the change.
* doc/lispref/variables.texi (Directory Local Variables): Update
accordingly.
Returning a cache remains unchanged, but the case of returning a
file (or pattern) is now changed to return the contaning
directory.
(dir-locals-read-from-file): Rename to `dir-locals-read-from-dir'
and make obsolete.
(dir-locals-read-from-dir): Simplify accordingly.
(hack-dir-local-variables): Simplify accordingly and rename a
variable.
Do the same for "permit", "enable", "prevent", and (where appropriate)
"require".

Pavel Raiskup reports that ${1+"$@"} runs afoul of a bug in /bin/sh
(derived from ksh 93t+ 2010-03-05). ${1+"$@"} works around an ancient
bug in long-dead shells, so remove the workaround.
* admin/check-doc-strings, configure.ac, lib-src/rcs2log:
Use plain "$@" rather than ${1+"$@"}.
* doc/misc/tramp.texi (External methods): Improve and modernize
wording for discussion of smbclient. There is no longer any
need to mention the laundry list of old MS Windows implementations
of SMB and CIFS, nor to mention CIFS. Also, give a URL for Samba.
