Remove the SOME_MACHINE_LISP distinction in src/Makefile.in.

See discussion in http://debbugs.gnu.org/8302

* configure.in (NS_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
(WINDOW_SUPPORT): Remove output variables that are no longer used.

* lib-src/makefile.w32-in (echolisp): Remove rule that is no longer needed.
(clean): No more echolisp.tmp.

* .bzrignore: Remove lib-src/echolisp.tmp.

* lisp/emacs-lisp/autoload.el (batch-update-autoloads):
Set autoload-excludes by parsing lisp/loadup.el rather than Makefiles.

* lisp/loadup.el: Update commentary.

* msdos/sed1x.inp (TOOLTIP_SUPPORT, WINDOW_SUPPORT):
* msdos/sed1v2.inp (MSDOS_SUPPORT, NS_SUPPORT, MOUSE_SUPPORT)
(TOOLTIP_SUPPORT, WINDOW_SUPPORT): No need to edit these any more.

* src/Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
(REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
(BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
(lisp): Set the order to that of loadup.el.
(shortlisp): Make it a copy of $lisp.
(SOME_MACHINE_LISP): Remove.
($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
Use just $shortlisp, not $SOME_MACHINE_LISP too.

-## This is the platform-specific list of Lisp files loaded into the

+## This is the list of all Lisp files that might be loaded into the
+## dumped Emacs.  Some of them are not loaded on all platforms, but
+## the DOC file on every platform uses them (because the DOC file is
+## supposed to be platform-independent).
+## It is arranged like this because it is easier to generate it
+## semi-mechanically from loadup.el this way.
+## Eg something like:
+##   sed -e 's/"[ )].*//' -n -e '/(load "/ s/.*load "//p' loadup.el | \
+##   grep -vE 'site-|ldefs-boot'
+## minus any duplicates.
+## Note that you cannot just add a ".elc" extension to every file,
+## since some of them are no-byte-compile (eg some language/ ones).
+##
+## Confusingly, term/internal is not in loadup, but is unconditionally
+## loaded by pc-win, which is.
 ##
 ## Note that this list should not include lisp files which might not
 ## be present, like site-load.el and site-init.el; this makefile
 ## expects them all to be either present or buildable.
 ##
-## Files which are loaded unconditionally (i.e., on all platforms) should
-## also be in shortlisp.  Files which are loaded conditionally (i.e., only
-## on some platforms) should instead be in SOME_MACHINE_LISP.
-##
 ## Place loaddefs.el first, so it gets generated first, since it is on
 ## the critical path (relevant in parallel compilations).
