show defvars which have no second argument.

(imenu--generic-function): Refer to imenu-generic-expression.
Fixes: debbugs:8638
src/w32.c: Include winioctl.h and aclapi.h.
(is_symlink, chase_symlinks, enable_privilege, restore_privilege)
(revert_to_self): Forward declarations of static functions.
<static BOOL g_b_init_get_security_info>:
<g_b_init_create_symbolic_link>: New static flags.
(globals_of_w32): Initialize them to zero.
(GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
(map_w32_filename): Improve commentary. Simplify switch.
(SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
headers (most versions of MinGW w32api don't).
(get_security_info, create_symbolic_link)
(get_file_security_desc_by_handle, is_symlink, chase_symlinks):
New functions.
(sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
in the argument file name.
(sys_access): Call unc_volume_file_attributes only if
GetFileAttributes fails with network-related error codes.
(sys_rename): Diagnose renaming of a symlink when the user doesn't
have the required privileges.
(get_file_security_desc_by_name): Renamed from
get_file_security_desc.
(stat_worker): New function, with most of the guts of 'stat', and
with addition of handling of symlinks and support for 'lstat'. If
possible, get file's attributes and security information by
handle, not by name. Produce S_IFLNK bit for symlinks, when
called from 'lstat'.
(stat, lstat): New functions, call 'stat_worker'.
(symlink, readlink, careadlinkat): Rewritten to create and resolve
symlinks when the underlying filesystem supports them.
lib/src/ntlib.c (lstat): New function, calls 'stat'.
nt/inc/sys/stat.h (S_IFLNK): Define.
(S_ISLNK): A non-trivial definition.
(lstat): Prototype instead of a macro that redirects to 'stat'.
lisp/files.el (file-truename): Don't skip symlink-chasing part on
windows-nt. Incorporate the resolution of 8+3 short aliases on
Windows into the loop that recursively chases symlinks. Compare
directory and its parent case-insensitively on MS-Windows and
MS-DOS.
etc/NEWS: Announce the symlink support on MS-Windows.
* nt/inc/ms-w32.h: Move here from ../src/s.
* nt/config.nt (config_opsysfile): Change to <ms-w32.h>.

* src/makefile.w32-in (TAGS, TAGS-gmake, MS_W32_H):
Update for new ms-w32.h location.
* lib-src/makefile.w32-in (MS_W32_H): Update for new ms-w32.h location.
* lib/makefile.w32-in (MS_W32_H): Update for new ms-w32.h location.
* lisp/emacs-lisp/authors.el (authors-renamed-files-alist): Add ms-w32.h.
* lisp/international/mule-cmds.el: Create
inactivate-current-input-method-function as an obsolete alias for
deactivate-current-input-method-function. See Katsumi Yamaoka in
<http://bugs.gnu.org/10150#46>.
* lisp/progmodes/autoconf.el (autoconf-definition-regexp):
Add AH_TEMPLATE, adjust submatch numbering.
(autoconf-font-lock-keywords, autoconf-imenu-generic-expression)
(autoconf-current-defun-function): Update for above change.
(autoconf-current-defun-function): First skip to end of current word.
* progmodes/python.el (python-shell-send-setup-max-wait): Delete var.
(python-shell-make-comint): accept-process-output at startup.
(run-python-internal): Set inferior-python-mode-hook to nil.
