* src/w32proc.c (Fw32_get_codepage_charset): Avoid compilation
warning.
(CompareStringW_Proc): New typedef.
(w32_compare_strings): Use it, to pacify compiler warnings under
"-Wincompatible-pointer-types".
* src/w32fns.c (GetDiskFreeSpaceExW_Proc)
(GetDiskFreeSpaceExA_Proc): New typedefs.
(Ffile_system_info): Use them, to pacify compiler warnings under
"-Wincompatible-pointer-types".
Copyright-paperwork-exempt: yes
Use slightly-longer cost vectors. Without this change,
calculate_direct_scrolling can have a subscript violation when
FRAME_LINES (frame) <= delta.
* src/scroll.c (calculate_scrolling, calculate_direct_scrolling)
(line_ins_del, do_line_insertion_deletion_costs):
Allocate and use slightly-larger cost vectors, ones based on
FRAME_TOTAL_LINES instead of FRAME_LINES.
* src/coding.c (encode_coding_object): Also initialize
coding->src_pos and coding->src_pos_byte when NILP (src_object).
This avoids later use of uninitialized storage.
This simplifies time conversions in other time zones.
It also prevents display-time-world tampering with TZ (Bug#21020).
* admin/admin.el (add-release-logs):
Use improved add-log-time-format API.
* admin/merge-gnulib (GNULIB_MODULES): Add time_rz, timegm.
(GNULIB_TOOL_FLAGS): Avoid flexmember, setenv, unsetenv.
* configure.ac (tzalloc): Remove test for this, since
Emacs no longer uses HAVE_TZALLOC directly.
* doc/lispref/os.texi (Time of Day, Time Conversion)
(Time Parsing):
* etc/NEWS: Document the new behavior.
Merge from gnulib, incorporating:

* lisp/vc/log-edit.el (log-edit-changelog-ours-p): Use new arg.
* nt/gnulib.mk: Propagate lib/gnulib.mk changes here.
Add rules for the time module, since they're now needed
for tzalloc etc.
* src/conf_post.h (getenv_TZ, setenv_TZ): New macros.
(emacs_getenv_TZ, emacs_setenv_TZ): New decls.
* src/editfns.c: Include errno.h.
(set_time_zone_rule): Omit unnecessary forward decl.
(initial_tz): Remove, replacing with ...
(local_tz, wall_clock_tz, utc_tz): New static vars and constants.
(tzeqlen): New constant; prefer it to (sizeof "TZ=" - 1).
(emacs_localtime_rz, emacs_mktime_z, xtzalloc, xtzfree)
(tzlookup): New static functions.
(init_editfns): New arg DUMPING. All uses changed.
(init_editfns): Omit most initialization if dumping, not if
!initialized. Initialize wall_clock_tz and local_tz.
(emacs_nmemftime, format_time_string): Time zone argument can now
be any time zone, not just a boolean for UTC or local time. All
callers changed.
(Fformat_time_string, Fencode_time, Fcurrent_time_string)
(Fcurrent_time_zone): New optional arg ZONE.
(Fdecode_time, Fset_time_zone_rule): ZONE arg can now also take
the same form as with the other new additions.
(decode_time_zone): Remove; no longer needed.
(tzvalbuf): Now file-scope.
(emacs_getenv_TZ, emacs_setenv_TZ): New functions.
(syms_of_editfns): Define Qwall.
* src/editfns.c (mktime_z) [!HAVE_TZALLOC]:
* src/systime.h (mktime_z, timezone_t, tzalloc, tzfree)
[!HAVE_TZALLOC]:
Remove; now supplied by gnulib.
* src/emacs.c (main):
* src/lisp.h (init_editfns): Adjust to init_editfns API change.
* src/xdisp.c (Fmove_point_visually): When lines are truncated,
simulate display in a window of infinite width, to allow move_it_*
functions reach positions outside of normal window dimensions.
Remove code that tried to handle a subset of these situations by
manual iteration of buffer text. (Bug#17777)
Crowe's patch in:
https://lists.gnu.org/archive/html/emacs-devel/2015-07/msg00106.html
A problem in this area has been reported by several users; see
Bug#16737, Bug#17101, Bug#17026, Bug#17172, Bug#19320, Bug#20283.
This fix differs from Mike Crowe's patch in that it should avoid a
race condition that could lose SIGIO signals. ignore_sigio dates
back to the 1980s when some platforms couldn't block signals, and
could only ignore them, which led to races when signals arrived
while being ignored. We shouldn't have to worry about those old
platforms now.
* src/dispextern.h, src/sysdep.c (ignore_sigio): Remove.
* src/emacs.c (shut_down_emacs):
Don't call ignore_sigio; unrequest_sigio should suffice.
* src/keyboard.c (kbd_buffer_store_buffered_event):
Use unrequest_sigio, not ignore_sigio.
(kbd_buffer_get_event):
Call request_sigio when getting the ball rolling again.
Improve the heuristic for distinguishing stack overflows from
other SIGSEGV causes (Bug#21004). Corinna Vinschen explained that
the getrlimit method wasn't portable to Cygwin; see:
https://www.cygwin.com/ml/cygwin/2015-07/msg00092.html
Corinna suggested pthread_getattr_np but this also has problems.
Instead, replace the low-level system stuff with a simple
heuristic based on known good stack addresses.
* src/eval.c, src/lisp.h (near_C_stack_top): New function.
* src/sysdep.c: Don't include <sys/resource.h>.
(stack_direction): Remove. All uses removed.
(stack_overflow): New function.
(handle_sigsegv): Use it instead of incorrect getrlimit heuristic.
Make SEGV fatal in non-main threads.
After stack overflow, command_loop calls init_eval, and this needs to
clear gcprolist and byte_stack_list (Bug#20996).
* src/alloc.c (init_alloc):
Move gcprolist and byte_stack_list initialization from here ...
* src/eval.c (init_eval): ... to here.
* src/macfont.m (macfont_family_cache): New variable.
(syms_of_macfont): Initialize it.
(macfont_available_families_cache): New variable.
(macfont_invalidate_family_cache, macfont_get_family_cache_if_present)
(macfont_set_family_cache, macfont_invalidate_available_families_cache)
(macfont_handle_font_change_notification)
(macfont_init_font_change_handler)
(macfont_copy_available_families_cache): New functions.
(macfont_create_family_with_symbol): Use font family caches.
(macfont_list, macfont_list_family): Use
macfont_copy_available_families_cache instead of
mac_font_create_available_families.
* src/process.c (wait_reading_process_output): Extend the behavior of
not breaking due to not finding output when a timer has lowered the
timeout to include when SIGIO lowers the timeout.
* src/process.c (wait_reading_process_output):
The patch for Bug#17647 returns too fast sometimes when reading
from any processes. Revert part of it, and limit the timeout more
sensibly (Bug#20978).
* src/process.c (wait_reading_process_output): Rename inner nsecs to
adaptive_nsecs. There is already an nsecs, and this function is
confusing enough (Bug#20978).
* src/process.c (wait_reading_process_output, status_notify):
Previously the function wait_reading_process_input was renamed to the
more logical wait_reading_process_output. Make its local variables
consistent with that change (Bug#20978).
* src/process.c (make-process, make-pipe-process, deactivate_process)
(wait_reading_process_output, read_process_output, send_process)
(init_process_emacs): ifdef ADAPTIVE_READ_BUFFERING was originally
added in case there was an operating system in which it was not
useful. That was 11 years ago and it hasn't happened. Make
development easier by not considering the effect of changes on a
theoretical OS where this is disabled (Bug#20978).
* src/w32fns.c (w32_wnd_proc): Don't change the mouse pointer
shape while a menu is in use. This started happening since we now
send WM_EMACS_SHOWCURSOR messages when the mouse moves.
* src/frame.c (x_set_font): If font_spec_from_name returns nil,
don't barf; instead, request a new fontset to be generated. This
avoids unnecessarily rejecting fonts named against XLFD rules. See
http://lists.gnu.org/archive/html/help-emacs-windows/2015-06/msg00001.html,
for the description of the original problem.
* lisp/faces.el (set-face-attribute): Don't be fooled too easily
by a hyphen in a font's name.
* src/keyboard.c (Fposn_at_x_y, Fposn_at_point): Allow X pixel
coordinate of -1, for a newline in a right-to-left line that
overflowed into the left fringe.
* etc/NEWS:
* doc/lispref/frames.texi (Mouse Tracking): Document the special
effect of setting 'track-mouse' to 'dragging'.
* lisp/textmodes/artist.el (artist-mouse-draw-continously):
* lisp/ruler-mode.el (ruler-mode-mouse-drag-any-column-iteration):
* lisp/mouse-drag.el (mouse-drag-throw):
* lisp/mouse.el (mouse-drag-line): Set 'track-mouse' to 'dragging'
to avoid changes in the shape of the mouse pointer.
* src/xdisp.c (define_frame_cursor1): Don't change the mouse
pointer shape when do_mouse_tracking has the value of 'dragging',
not just any non-nil value. (Bug#20934)
(syms_of_xdisp): DEFSYM 'dragging'.
* src/gnutls.c (Fgnutls_boot): Use the %x conversion specifier in
the call to 'error', instead of the unsupported %u. Reported by
lo2net <fangtao0901@gmail.com>. (Bug#20908)
* src/w32fns.c: Include windowsx.h.
(w32_wnd_proc): If the mouse moved and the mouse pointer is
invisible, make it visible again even when the main (Lisp)
thread is busy.
* src/w32term.c (w32_toggle_invisible_pointer): Rather then
garbaging the frame have the input thread call SetCursor.
* src/w32fns.c (w32_wnd_proc): Handle f->pointer_invisible
for WM_SETCURSOR and WM_EMACS_SETCURSOR cases.
* src/w32term.c (w32_hide_hourglass): Handle
f->pointer_invisible.
(w32_toggle_invisible_pointer): New function.
(w32_create_terminal): Add w32_toggle_invisible_pointer as
toggle_invisible_pointer_hook for this terminal.
