(flymake-make-diagnostic): New optional arg overlay-properties.
(flymake--highlight-line): Use it.

* lisp/vc/vc.el (vc-find-revision-no-save): Use decode-coding-inserted-region

it can return non-nil even if 'key' is nil.  Improve implementation to
avoid constructing an intermediate list of all keys.
(map-merge-with): Use 'eql' rather than `eq'.

Fix bug when hashing reversed buffer regions

* src/fns.c (extract_data_from_object): When checking

* doc/misc/tramp.texi (Ad-hoc multi-hops): Involved methods must
be inline methods.

Add make_vector and make_nil_vector

emacsclient: avoid background chatter

* lib-src/emacsclient.c (process_grouping): New function.
(act_on_signals, main): Use it.
(main): Omit "Waiting for Emacs..." and later "\n" messages
if in background, since that messes up the screen.

Fix emacsclient hang when backgrounded

Problem reported by Kaushal Modi in:
https://lists.gnu.org/r/emacs-devel/2018-12/msg00083.html
The tcdrain call replaced an fdatasync call which had no
effect on the tty, so removing it entirely shouldn’t cause
problems.  The fdatasync call replaced an fsync call which
also had no effect on the tty, and the fsync call seems to be
badly-merged revenant of emacsclient’s old (circa 2004) way of
communicating to and from Emacs via FILE * streams, where
fsync was apparently needed when talking to sockets.
* lib-src/emacsclient.c [!DOS_NT]: Don’t include termios.h.
(flush_stdout): Remove.  All callers removed.
(main): Do not drain the tty after "Waiting for Emacs..."
message.  There should be no need to drain, and draining it
might send us a SIGTTOU.  Do not fflush stdout just before
exiting, as exiting does that for us.

struct image_type layout is private to image.c

* src/dispextern.h (struct image_type): Move from here ...
* src/image.c (struct image_type): ... to here.

Avoid an error on exit in a build without threads

* lisp/simple.el (list-processes--refresh): Avoid signaling an
error in a build --without-threads.  (Bug#33629)

emacsclient: fix typo on recent socket-leak change

This ports to POSIXish platforms like macOS that lack SOCK_CLOEXEC.
Fix suggested by Eli Zaretskii in:
https://lists.gnu.org/r/emacs-devel/2018-12/msg00055.html
* lib-src/emacsclient.c (set_local_socket):
Don’t use SOCK_CLOEXEC; that’s cloexec_socket’s job.

Fix WINDOWSNT/DOS_NT build

Recent changes in sysdep.c and emacsclient unnecessarily
removed useful code from DOS_NT builds.  This changeset
reinstates that code.
* nt/inc/ms-w32.h (tcdrain): Redirect to _commit.
(fdatasync): No need to redirect anymore.

* lib-src/emacsclient.c (flush_stdout): Don't avoid calling
tcdrain on DOS_NT platforms.

* src/sysdep.c (reset_sys_modes): Don't ifdef away the call to
tcdrain on DOS_NT platforms.

A few further fixes of window internals description

* doc/lispref/internals.texi (Window Internals): Add a few
more items and clarify description of some others.

emacsclient: don’t leak socket to child processes

* lib-src/emacsclient.c [!WINDOWSNT]: Include fcntl.h.
(cloexec_socket): New function.
(set_tcp_socket, set_local_socket): Use it.

Use tcdrain, not fdatasync, to drain ttys

fdatasync is for storage devices, not ttys.
* admin/merge-gnulib (GNULIB_MODULES): Remove fdatasync.
* lib/fdatasync.c, m4/fdatasync.m4: Remove.
* lib-src/Makefile.in (LIB_FDATASYNC):
* src/Makefile.in (LIB_FDATASYNC):
Remove.  All uses removed.
* lib-src/emacsclient.c [!DOS_NT]:
Include <termios.h>, for tcdrain.
* lib-src/emacsclient.c (flush_stdout):
* src/sysdep.c (reset_sys_modes): On ttys, use tcdrain instead
of fdatasync (except don’t use either function if DOS_NT).
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.

Update from Gnulib

This incorporates:
2018-11-30 memrchr: port better to clang
2018-11-21 mktime: add libc-config dependency
* build-aux/config.guess, build-aux/config.sub, lib/memrchr.c:
Copy from Gnulib.
* m4/gnulib-comp.m4: Regenerate.

emacsclient: fix symlink/socket race

* lib-src/emacsclient.c (socket_status): New arg UID.
All uses changed.
(set_local_socket): Don’t create the unbound socket unless the
initial sanity checks on the socket file succeed; this
simplifies cleaning it up.  Check socket ownership again
after connecting, to fix a race (Bug#33366).

the expected behavior.
