Provide a new window parameter 'min-margins' which allows to
ignore the actual widths of a window's margins when splitting or
resizing that window horizontally.  This should serve as a
workaround for handling the problems raised by Bug#24193.

* lisp/window.el (window--min-size-1): Handle new window
parameter 'min-margins'.
(split-window): Fix text of error messages.
* doc/lispref/windows.texi (Window Parameters): Describe new
parameter 'min-margins'.

* config.bat:
* msdos/sedlisp.inp:
* msdos/sedlibmk.inp:
* msdos/sedleim.inp:
* msdos/sedadmin.inp:
* msdos/sed6.inp:
* msdos/sed3v2.inp:
* msdos/sed2v2.inp:
* msdos/sed1v2.inp: Adapt to Emacs 25.

* src/process.c (remove_slash_colon): Move out of "#ifdef
subprocesses" block, as it its called unconditionally.  Move
ADD_SUBFEATURE calls into "#ifdef subprocesses" block, as they
reference variables only defined in that block.
* src/msdos.h: Provide prototypes for IT_set_frame_parameters,
faccessat, msdos_fatal_signal, syms_of_msdos, pthread_sigmask,
dos_keysns, dos_keyread, run_msdos_command, and
syms_of_win16select, to avoid compiler warnings.
* src/msdos.c (SYS_ENVIRON): Define to either '_environ' or
'environ', depending on the DJGPP version.
Remove declarations of externally-visible Lisp objects, like
Qbackground_color and Qreverse.
(run_msdos_command): First argument is not signed, not unsigned.
Use SYS_ENVIRON.
(sys_select): Use 'timespec_cmp' instead of 'timespec_sign', as
the latter doesn't work when 'time_t' is an unsigned data type.
This caused idle timers to behave incorrectly: they only fired
after a keyboard input event.
* src/frame.c (adjust_frame_size) [MSDOS]: Account for
FRAME_TOP_MARGIN that isn't counted in the frame's number of
lines, but dos_set_window_size needs it to be added.
* src/lread.c (INFINITY, NAN) [DJGPP < 2.05]: Provide definitions.
* src/fns.c (sort_vector_copy) [__GNUC__ < 4]: Provide a prototype
that works around compilation errors with older GCC versions.
* src/w16select.c: Don't declare QCLIPBOARD and QPRIMARY as Lisp
Objects.
* src/filelock.c [MSDOS]: Ifdef away most of the code.  Provide
no-op implementations for 'lock_file' and 'unlock_file'.
(Ffile_locked_p) [MSDOS]: Always return nil.  This avoids multiple
ifdefs in all users of filelock.c functionality.
* src/conf_post.h (EOVERFLOW, SIZE_MAX) [DJGPP < 2.04]: Define.
* src/emacs.c [MSDOS]: Include dosfns.h, to avoid compiler
warnings.
* src/dosfns.h: Provide prototypes for dos_cleanup,
syms_of_dosfns, and init_dosfns.
* src/deps.mk (atimer.o): Depend on msdos.h.
(emacs.o): Depend on dosfns.h.
* src/atimer.c [MSDOS]: Include msdos.h, to avoid compiler
warnings.

* lisp/window.el (window--adjust-process-windows): Skip the body
if 'process-list' is not available.  This avoids failure to start
up on MS-DOS.
* lisp/vc/diff.el (diff-no-select): Test 'make-process', not
'start-process', as the latter is now available on all platforms.
* lisp/textmodes/ispell.el (ispell-async-processp): Replace
'start-process' with 'make-process' in a comment.
* lisp/term/internal.el (IT-unicode-translations): Modify and add
a few translations to display Info files with Unicode markup.  Fix
an ancient off-by-one mismatch error with Unicode codepoints.
* lisp/progmodes/compile.el (compilation-start): Test
'make-process', not 'start-process', as the latter is now
available on all platforms.
* lisp/man.el (Man-build-man-command, Man-getpage-in-background):
Test 'make-process', not 'start-process', as the latter is now
available on all platforms.
* lisp/international/mule-cmds.el (set-coding-system-map): Test
'make-process', not 'start-process', as the latter is now
available on all platforms.
* lisp/eshell/esh-cmd.el (eshell-do-pipelines-synchronously): Doc
fix.
(eshell-execute-pipeline): Test 'make-process', not
'start-process', as the latter is now available on all platforms.

This avoids an issue with save-selected-window (from walk-windows)
failing if frame.el is not loaded, eg if the terminal is resized
during startup of a -nw CANNOT_DUMP build.  (Bug#23369).

When either fringe width is zero, Emacs reserved one column for a
continuation glyph. Terminal windows does not take this into
account when the frame is resized.

* lisp/window.el (window-adjust-process-window-size): Use
`window-max-chars-per-line' instead of `window-body-width'.
* lisp/term.el (term-window-width): Remove function. (It does the
same as `window-max-chars-per-line' but without recent bug fixes.)
(term-mode): Use `window-max-chars-per-line' instead of
`term-window-width'.

Backport

(cherry picked from commit 5b540328)

* lisp/window.el (window-max-chars-per-line): Account for
'left-fringe-width' and 'right-fringe-width' variables.

* doc/lispref/windows.texi (Window Sizes): Document the effect on
window text width when setting the width of one or both fringes to
zero.
* doc/emacs/display.texi (Fringes): Document the effect on window
text width when setting the width of one or both fringes to zero.
(Bug#22891)

* lisp/window.el (enlarge-window, shrink-window): Consistently
signal user-error instead of error.  Resize minibuffer window by
delta lines instead of pixels.  When a window cannot be resized,
signal an error only when this function was invoked by a command
in the enlarge-/shrink-window group (this restores the behavior
before the fix of bug#22723 for the non-interactive case).

* lisp/window.el (adjust-window-trailing-edge): Fix mismatched
parenthesis.
(shrink-window, enlarge-window): Fix bug#22723 where windows
with preserved size would not get resized.  Also now signal an
error when the window cannot be shrunk or enlarged as requested.

Do the same for "permit", "enable", and "prevent".

together with the six variables indirecting to the pertinent group

Mostly these fixes prevent the transliteration of apostrophes
that should stay apostrophes.  Also, prefer curved quotes in
Bahá’í proper names, as that’s the preferred Bahá’í style and
these names are chock-full of non-ASCII characters anyway.
