* lisp/vc/vc.el (vc-find-revision-no-save): New defcustom (bug#33319).

call either vc-find-revision-no-save or vc-find-revision-save.
(vc-find-revision-save): Rename from vc-find-revision.
(vc-find-revision-no-save): New function.

Let-bind vc-find-revision-no-save to t.

(diff-find-source-location): Call vc-find-revision for
non-nil values of 'other', diff-vc-backend, diff-vc-revisions.

diff-vc-revisions to the list of used revisions.

* m4/std-gnu11.m4, m4/stdint.m4:
Copy from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate:
POSIX says sh ~/foo should act like $HOME/foo even if $HOME is
relative, so be consistent with that (Bug#33255).
* admin/merge-gnulib (GNULIB_MODULES): Add dosname.
* src/buffer.c (init_buffer): Use emacs_wd to get
initial working directory with slash appended if needed.
(default-directory): Say it must be absolute.
* src/emacs.c (emacs_wd): New global variable.
(init_cmdargs): Dir arg is now char const *.
(main): Set emacs_wd.
* src/emacs.c (main) [NS_IMPL_COCOA]:
* src/fileio.c (Fexpand_file_name):
Use get_homedir instead of egetenv ("HOME").
* src/fileio.c: Include dosname.h, for IS_ABSOLUTE_FILE_NAME.
(splice_dir_file, get_homedir): New functions.
* src/xrdb.c (gethomedir): Remove. All callers changed
to use get_homedir and splice_dir_file.
* test/src/fileio-tests.el (fileio-tests--relative-HOME): New test.
* lisp/files.el (dir-locals-read-from-dir): Reduce scope of
`read-circle' let-binding to go around the `read' call only.
Otherwise it can interfere with loading of files which use the
circular read syntax (e.g., executing the setf expression in
`dir-locals-set-class-variables' may require loading gv.elc).
Problem reported by Thomas Fitzsimmons (Bug#33174).
Do not merge to master, as we have a better fix there.
* src/Makefile.in (emacs$(EXEEXT)):
(bootstrap-emacs$(EXEEXT)):
Unset EMACS_HEAP_EXEC before invoking temacs.
Problem reported by Thomas Fitzsimmons (Bug#33174).
* src/emacs.c (main): Adjust to sysdep.c changes.
* src/sysdep.c (exec_personality): New static var.
(disable_address_randomization): Remove, replacing with ...
(maybe_disable_address_randomization): ... this new function.
Do not set or use an environment variable; use a command-line
argument instead, and set the new static var. Migrate the emacs.c
personality-change code to here, where it belongs.
(emacs_exec_file): Simplify by using new static var.
I ran into this problem on Ubuntu 18.04.1 LTS.
* src/gnutls.c (HAVE_GNUTLS_CIPHER_GET_IV_SIZE)
(HAVE_GNUTLS_CIPHER_GET_TAG_SIZE, HAVE_GNUTLS_DIGEST_LIST):
New macros. This uses the same style as the other
macros that depend on GnuTLS version, as opposed to trying
to do things a bit more cleverly.
(gnutls_cipher_get_iv_size, gnutls_cipher_get_tag_size)
(gnutls_digest_list, gnutls_digest_get_name):
Define these macros only if they will be used.
* lisp/files.el (move-file-to-trash): Behave like the doc
string says: check whether 'system-move-file-to-trash' is
defined before testing that 'trash-directory' is non-nil.
(Bug#33335)
* src/process.c (dissociate_controlling_tty): New function.
(create_process): Use it to dissociate controlling tty if setsid
fails, which happens on Darwin after a vfork (Bug#33154).
Do this on all platforms, not just on Darwin, as a similar
problem is plausible elsewhere.
* src/callproc.c (call_process): Use the new function here, too,
for consistency and to avoid duplicate code.
* lisp/emacs-lisp/ring.el (ring-resize): New function. (Bug#32849)
* doc/lispref/sequences.texi (Rings): Document new function 'ring-resize'.
* etc/NEWS: Document new function 'ring-resize'.
* test/lisp/emacs-lisp/ring-tests.el (ring-test-ring-resize): New tests.
* src/editfns.c (Fgroup_name): Fix the doc string. Move
closer to the "group" functions.
* src/w32.c (getgrgid): Return NULL if GID is not the group ID
of the user of this Emacs session
* test/src/editfns-tests.el (test-group-name): Rename from
'group-name'. Add tests for non-Posix hosts. Test error when
the argument to group-name is invalid.
* etc/NEWS: Fix wording of last added entry.
* doc/lispref/functions.texi (Anonymous Functions):
* lisp/subr.el (lambda): Note that under lexical binding a lambda form
yields a closure object (Bug#33199).
* lisp/bookmark.el (bookmark-jump-other-frame): New function.
Bind in bookmark-map.
(bookmark-bmenu-other-frame): New function.
Bind in bookmark-bmenu-mode-map.
Patch applied by Karl Fogel.
* lisp/window.el (display-buffer-overriding-action)
(display-buffer-alist, display-buffer-base-action)
(display-buffer-fallback-action, display-buffer-assq-regexp)
(display-buffer): Rewrite doc-strings using suggestions by
Alan Mackenzie <acm@muc.de>.
(display-buffer-use-some-frame): Adjust doc-string and
reformat code.
* doc/lispref/windows.texi (Buffer Display Action Alists):
Make docs on 'window-height', 'window-width' and
'preserve-size' entries more accurate.
