* mk/targets.mk: Add contrib files already for autoloads so that
uncompiled can have contrib/lisp/ added, too. Remove all files from
contrib/lisp/ that are found in lisp/ for `cleanlisp´ so that
switching between different contrib configurations becomes easier.
Remove variable ORG_TO_LISP since it is not needed anymore.
* Makefile: Include default.mk and targets.mk from mk/ where they've
been moved to.
* README_maintainer: Rename utils to make throughout.
* doc/Makefile: Rename utils to make throughout.
* doc/org.texi: Remove reference to utils/, x11idle.c is now in
contrib/scripts.
* mk/make_emacs_changelog: Add mk/ to list of directories not to be
reported in Emacs' ChangeLog. Also retain utils/ and re-add
UTILITIES; add a comment explaining why these need to stay.
* mk/default.mk: Rename utils to make throughout. Include version.mk
from mk/ where it's been moved to.
* mk/targets.mk: Rename utils to make throughout.
* mk/server.mk: Rename utils to make throughout. Only put those files
from mk/ into the archives that are needed outside the server:
default.mk targets.mk version.mk and org-fixup.el.
* lisp/org-compat.el: Rename utils to make throughout.
* .gitignore: Rename utils to make throughout.
