Here, we use the generic window-system configuration system we just
implemented to support the w32 window-system in the mainline build
under Cygwin. (Previously, the w32 window system could only be
compiled as part of the NT-native Emacs build process.)
The changes in this patch need to be applied atomically in order to
avoid breaking Emacs. The changes include:
- Changes throughout the Lisp and C code to not assume that
NT Emacs and the w32 window system are synonymous.
- Wiring up the regular select(2) event loop to Windows messages
- Cleaning up the w32 drag-and-drop receiving code.
- Exposing Cygwin path conversion functions to elisp.
- Unicode file dialog support when compiling for Cygwin.
- Splitting the w32 term lisp initialization code into code
applicable to any w32 window-system and code specific to
system-type windows-nt.
- Integrating the old and new w32 code into the build system.

(isearch-query-replace): Let-bind replace-search-function and
replace-re-search-function.

value of isearch-lax-whitespace and isearch-regexp-lax-whitespace.

condition for C-q SPC.

(isearch-lazy-highlight-lax-whitespace)
(isearch-lazy-highlight-regexp-lax-whitespace): New variables.
(isearch-lazy-highlight-new-loop): Use them.
(isearch-lazy-highlight-search): Don't let-bind search-spaces-regexp.
* lisp/term.el: (term-mode-map): Use easymenu for In/Out, Complete menus.
(term-pager-break-map): Initialize in the defvar.
(term-terminal-menu, term-signals-menu): Define with easymenu.

(term-pager-menu): New, extracted from term-process-pager.
(term-mode, term-char-mode, term-process-pager): Use easymenu-add.
(term-update-mode-line): Propertize line/char and page items.
(term-process-pager): Move keymap initialization elsewhere.
Fixes: debbugs:11957
* window.el (switch-to-prev-buffer): Handle additional values of
BURY-OR-KILL argument. Don't switch in minibuffer window.
(switch-to-next-buffer): Don't switch in minibuffer window.
(quit-restore-window): New function based on quit-window.
Handle additional values of former KILL argument.
(quit-window): Call quit-restore-window with appropriate
interpretation of KILL argument.
(display-buffer-below-selected): New buffer display action
function.
src/w32uniscribe.c (uniscribe_shape): Handle correctly the case of
more than one grapheme cluster passed to the shaper: compute the
offset adjustment values separately for each cluster.
src/image.c: Restore mistakenly removed inclusion of w32.h. Without
it, GCC doesn't see prototypes of w32_delayed_load, and complains
about implicit conversions from integer to pointer.
This change streamlines the window system selection code in
configure.in and moves many common function declarations from
window-specific headers to frame.h. It introduces a new TERM_HEADER
macro in config.h: we set this macro to the right header to use for
the window system for which we're compiling Emacs and have source
files include it indirectly. This way, we don't have to teach every
file about every window system.
* doc/lispref/numbers.texi (Random Numbers): Document new behavior of
the calls (random) and (random STRING).
* etc/NEWS: Document new behavior of (random), (random "string").
* lisp/play/5x5.el, lisp/play/animate.el, lisp/play/cookie1.el:
* lisp/play/dissociate.el, lisp/play/doctor.el, lisp/play/dunnet.el:

* lisp/play/blackbox.el (bb-init-board):
* lisp/play/life.el (life):
* lisp/server.el (server-use-tcp):
* lisp/type-break.el (type-break):
Remove unnecessary call to (random t).
* lisp/net/sasl.el (sasl-unique-id-function):
Change (random t) to (random), now that the latter is more random.
* lisp/play/life.el (life-initialized): Remove no-longer-needed var.
* lisp/gnus/gnus-sync.el (gnus-sync-lesync-setup):
* lisp/gnus/message.el (message-canlock-generate, message-unique-id):
Change (random t) to (random), now that the latter is more random.
* lisp/org/org-id.el (org-id-uuid):
Change (random t) to (random), now that the latter is more random.
* src/emacs.c (main): Call init_random.
* src/fns.c (Frandom): Set the seed from a string argument, if given.
Remove long-obsolete Gentzel cruft.

(init_random): New function.
* lisp.h (mark_ttys): Remove prototype.
* alloc.c (Fgarbage_collect): Remove redundant (and the only) call

the frames which are reachable from Vframe_list.
* term.c (mark_ttys): Remove.
(init_tty): Safely initialize 'top_frame' slot with Qnil.
* src/lread.c (init_lread): For out-of-tree builds, only add the
