* lisp/calendar/todo-mode.el (todo-move-item, todo-item-undone)
(todo-category-completions): Use 'ngettext' instead of hard-coding
plural forms by hand.
Problem reported by Mattias Engdegård in:
https://lists.gnu.org/r/emacs-devel/2020-12/msg01626.html
* configure.ac: If the scratch_buffer module is enabled, create
lib/malloc and (if doing dependencies) lib/deps/malloc.
* lib/Makefile.in (DEPFLAGS) [AUTO_DEPEND]: No longer any need to
squash lib dependencies into a single directory.
(clean): Also remove */*.o and $(DEPDIR)/*/*.d, to clean out
malloc/*.o and deps/malloc/*.d. Just remove *.d files in
dependencies so that rm does not complain about not being able to
remove deps/malloc.
(extraclean): Also remove malloc, if it is empty.
* lisp/emacs-lisp/package.el (package--files-load-history): We're
comparing the truenames, so ensure that we've using that
everywhere. This fixes problems when there's symlinks in the paths.
* lisp/emacs-lisp/package.el (package--files-load-history)
(package--list-of-conflicts): Factor out from...
(package--list-loaded-files): ... this function for easier
debuggability.

There was already charset file present in etc/charsets for IBM2XX
character sets but there wasn't definitions for them in Emacs.
Add character set and coding system definitions for them.
* lisp/language/japanese.el (ibm281, ibm290):
* lisp/language/european.el (ibm256, ibm273, ibm274, ibm277)
(ibm278, ibm280, ibm284, ibm285, ibm297):
* lisp/language/english.el (ibm275): New coding systems.
* lisp/international/mule-conf.el (ibm256, ibm273, ibm274)
(ibm275, ibm277, ibm278, ibm280, ibm281, ibm284, ibm285, ibm290)
(ibm297): New charsets.
posix_spawn is less error-prone than vfork + execve, and can make
better use of system-specific enhancements like 'clone' on Linux. Use
it if we don't need to configure a pseudoterminal.
* src/Makefile.in (LIB_POSIX_SPAWN): New variable.
(LIBES): Use it.
* src/callproc.c (emacs_spawn): Use posix_spawn on Unix-like system if
we don't need to set up a pseudoterminal.
posix_spawn is less error-prone than vfork + exec, and can make use of
system-specific optimizations like `clone' on Linux. Import Gnulib
replacement so that we can use recent additions like
`posix_spawn_file_actions_addchdir'.
The only manual change are to admin/merge-gnulib and .gitignore. All
other changes are due to rerunning merge-gnulib.
* admin/merge-gnulib (GNULIB_MODULES): Add posix_spawn-related
modules.
* .gitignore: Add new generated files.
The latest Gnulib merge brought in free-posix, which causes 'free'
to preserve errno. This lets us simplify some Emacs code that
calls 'free'.
* admin/merge-gnulib (GNULIB_MODULES): Add free-posix.
This module is pulled in by canonicalize-lgpl anyway,
so we might as well rely on it.
* lib-src/emacsclient.c (get_current_dir_name):
Sync better with src/sysdep.c.
* lib-src/etags.c (process_file_name, etags_mktmp):
* lib-src/update-game-score.c (unlock_file):
* src/fileio.c (file_accessible_directory_p):
* src/sysdep.c (get_current_dir_name_or_unreachable):
Simplify by assuming that 'free' preserves errno.
* src/alloc.c (malloc_unblock_input):
Preserve errno, so that xfree preserves errno.
* src/sysdep.c (get_current_dir_name_or_unreachable):
Simplify by using strdup instead of malloc+memcpy.
No need for realloc (and the old code leaked memory anyway on
failure); just use free+malloc.
* src/gtkutil.c (xg_item_label_same_p): Simplify. Without this
simplification, GCC (Ubuntu 10.2.0-13ubuntu1)
-Wanalyzer-null-argument complains about use of NULL where
non-null expected as argument of strcmp.
* lisp/progmodes/cperl-mode.el (cperl-init-faces): %array[0, 1]
should use the array face, not the hash one (bug#45373).
Copyright-paperwork-exempt: yes
* src/w32.h (set_process_dir):
* src/w32proc.c (set_process_dir): Change the argument to 'const
char *'.
* src/lisp.h (make_environment_block):
* src/callproc.c (make_environment_block): Now returns 'char **'.
(exec_failed) [DOS_NT]: Remove unused function.
* src/callproc.c (child_setup): NEW_ARGV and ENV are now 'char **'.
Making them 'const' breaks the MinGW build and is not needed for
other platforms.
* src/callproc.c (emacs_spawn): ARGV and ENVP arguments are now
'char *', for the same reason.
* src/process.c (create_process): Adapt to above changes.
Getting the vfork + execve combination right isn't easy, and the code
was partially duplicated between callproc.c and process.c. Centralize
the spawn operation in a single function that deals with the nasty
details. Going forward, we should be able to use posix_spawn from
either libc or Gnulib (or CreateProcessW on Windows) in the non-pty
case.
* src/callproc.c (emacs_spawn): New function to start an asynchronous
subprocess. Merge code from 'call_process' and 'create_process' into
this function.
(call_process): Use new 'emacs_spawn' function.
(child_setup): Make static, since there are no users outside this
compilation unit left.
(CHILD_SETUP_TYPE): Move from header file, since there are no users
outside this compilation unit left.
* src/process.c (create_process): Use new 'emacs_spawn' function.
Also fix three infinite loops. The new cache accelerates backward searches
for struct beginnings in c-looking-at-or-maybe-in-bracelist.
* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): In the final loop
over unary operators, add a check (> (point) lim) to avoid certain infinite
loops.
(c-beginning-of-decl-1): In the first loop add a similar check on point and
lim.
(c-laomib-loop): New function extracted from
c-looking-at-or-maybe-in-bracelist.
(c-laomib-cache): New buffer local variable.
(c-laomib-get-cache, c-laomib-put-cache, c-laomib-fix-elt)
(c-laomib-invalidate-cache): New functions which implement the cache.
(c-looking-at-or-maybe-in-bracelist): Replace two invocations of
c-go-up-list-backwards with calls to c-parse-state. Extract the new function
c-laomib-loop. Insert code which calls c-laomib-loop minimally, with the help
of the new cache.
* lisp/progmodes/cc-mode.el (c-basic-common-init): Initialise the new cach
(at mode start).
(c-before-change): Invalidate the new cache.
(c-fl-decl-start): Add an extra check (> (point) bod-lim) to prevent looping.
Determine the enclosing brace to pass as arguments to
c-looking-at-or-maybe-in-bracelist.
