ab4df9ce7d Byte compiler: fix spurious warnings "might not be defined at runtime".
Also initialize byte-compile-noruntime-functions between runs.

bytecomp.el (byte-compile-new-defuns): New variable.
(byte-compile-initial-macro-environment): For eval-when-compile: bind
byte-compile-unresolved-functions and byte-compile-new-defuns around
byte-compile-top-level, to prevent spurious entries being made.
(byte-compile-warn-about-unresolved-functions): Check whether function is in
byte-compile-new-defuns before emitting a warning about it.
(byte-compile-from-buffer): Initialize new variable and
byte-compile-noruntime-functions to nil.
(byte-compile-file-form-require): record all new functions defined by a
`require' in byte-compile-new-defuns.
(byte-compile-file-form-defmumble): record the new alias in
byte-compile-new-defuns.

d696d62fea Simplify recording of main thread's ID on MS-Windows
* src/w32term.c (w32_initialize):
* src/w32console.c (initialize_w32_display):
* src/w32fns.c (globals_of_w32fns): Don't record the main thread
ID independently for each type of session (GUI, TTY, batch).
* src/w32term.c (w32_init_main_thread): New function, records the
main thread's thread ID.
* src/w32term.h: Add prototype for w32_init_main_thread.
* src/emacs.c (main) [WINDOWSNT]: Call w32_init_main_thread.

* src/emacs-module.c [WINDOWSNT]: Rename main_thread_id to
main_thread, for consistency with other threading libraries.  All
users changed.  Include w32term.h.
(check_main_thread) [WINDOWSNT]: Simplify the test: no need to
make sure the main thread is alive, as we hold a handle on it
opened by w32_init_main_thread.
(module_init) [WINDOWSNT]: Reuse the thread ID recorded by
w32_init_main_thread, instead of calling the requisite APIs once
more.

* src/window.c (grow_mini_window, shrink_mini_window): Set the
frame's 'window_sizes_changed' flag.
* src/xdisp.c (redisplay_internal): Call the hooks on
'window-size-change-functions' if the call to 'echo_area_display'
sets the frame's 'window_sizes_changed' flag.
(syms_of_xdisp) <window-size-change-functions>:
Update doc string to indicate the mini-window resizes trigger a
call to the hooks, and don't promise that will happen "before
redisplay".  (Bug#19576, Bug#21333)

* doc/lispref/windows.texi (Window Hooks): Update the description
of 'window-size-change-functions'.

default value into a separate `add-hook' call (bug#21964).

Don't declare the xref-backend-functions variable.

75a1d009f7 Fixed bug#19576: `write-file' saves wrong buffer.
If a function on the hook `window-size-change-functions' doesn't
restore the current buffer, functions that save and restore the
current window configuration (like `y-or-no-p') could silently
change the current buffer.  When `write-file' asked the user
confirmation to overwrite a file, `y-or-no-p' changed the current
buffer, and the wrong buffer was saved to the file.

* lisp/follow.el (follow-windows-start-end): Call `select-frame'
using the `norecord' parameter.
(follow-window-size-change): Restore current buffer. Call
`select-frame' using the `norecord' parameter. Cleanup.

e61f1c3c8b Module function arg counts are ptrdiff_t, not int
* src/emacs-module.c (struct module_fun_env)
(module_make_function, module_funcall, Fmodule_call):
* src/emacs-module.h (struct emacs_runtime, struct emacs_env_25):
Use ptrdiff_t, not int, for arg counts.
* src/emacs-module.c (module_make_function): Don’t bother
checking arity against MOST_POSITIVE_FIXNUM, as that’s
unnecessary here.  Make the checking clearer by negating it.
(module_make_function, Fmodule_call): No need to use xzalloc
since the storage doesn’t need to be cleared.
(module_funcall): Don’t use VLA, since C11 doesn’t guarantee support
for it, and many implementations are buggy with large VLAs anyway.
Use SAFE_ALLOCA_LISP instead.
(module_vec_set): Don’t crash if i < 0.
(module_vec_get): Don’t crash if i < MOST_NEGATIVE_FIXNUM.
(module_vec_set, module_vec_get): Do fixnum checks only when
i is out of array bounds, for efficiency in the usual case.
(Fmodule_load): Simplify fixnum range check.
(Fmodule_call): Simplify arity check.  Use xnmalloc to detect
integer overflow in array allocation size.

24be1c8460 Improve MS-Windows implementation in dynlib.c
* src/dynlib.c [WINDOWSNT]: Include errno.h, lisp.h, and w32.h.
No need to include windows.h, as w32.h already does that.
<dynlib_last_err>: New static variable.
(dynlib_reset_last_error): New function.
(dynlib_open): Convert forward slashes to backslashes.  Convert
file names from UTF-8 to either UTF-16 or the current ANSI
codepage, and call either LoadLibraryW or LoadLibraryA.  If the
argument is NULL, return a handle to the main module, like
'dlopen' does.  Record the error, if any, for use by dynlib_error.
(dynlib_sym): Check the handle for validity. Record the error, if
any, for use by dynlib_error.
(dynlib_error): Call w32_strerror to produce the error string, and
zero out the last error code, like dlerror does.
(dynlib_close): Check the handle for validity.  Record the error,
if any, for use by dynlib_error.  Don't call FreeLibrary with a
handle for the main module.
* src/w32.c (globals_of_w32): Call dynlib_reset_last_error.

c593538968 Revert `open-line' electric-indent sensitivity
* lisp/simple.el (open-line): Remove electric indent code.
  (electric-indent-just-newline): Don't declare.

* test/automated/simple-test.el (open-line-indent): Adjust test.

This partly reverts Artur Malabarba's change that added electric
indent sensitivity to `open-line' (Oct 24 22:26:27 2015 +0100, git
commit bd4f04f86), and adjusts a new test he added right afterwards
(Sat Oct 24 23:43:06 2015 +0100, git commit 207f235e3) accordingly.
However, the new INTERACTIVE argument to `open-line', which he also
added in the first commit, is not reverted here.

See the thread "Questioning the new behavior of `open-line'." on the
Emacs Devel mailing list, and in particular this message:

92949781eb Prefer signed integer types in module code
Generally speaking, at the C level the Emacs source code prefers
signed types like ‘ptrdiff_t’ to unsigned types like ‘size_t’,
partly to avoid the usual signedness confusion when comparing values.
Change the module API to follow this convention.
Use ‘int’ for small values that can’t exceed INT_MAX.

d9b300af5c Omit ‘const’ on locals
Remove ‘const’ qualifier from locals that were newly added.
We don’t normally bother declaring locals with ‘const’ even
though they are not modified, for the same reason we don’t
bother declaring them with ‘register’ even though their
addresses are not taken; the advantage in compile-time
checking isn’t worth the loss of readability.

* src/emacs-module.c (module_extract_integer)

* src/emacs-module.h (struct emacs_env_25):
Prefer intmax_t to int64_t.  This doesn’t change the generated
code on any of the machines Emacs currently ports to, but it’s
at least in theory more future-proof as C99 doesn’t guarantee
that int64_t exists.
