ldefs-boot.el wont cause conflicts per se, because it is not generated
during the build, nor is it versioned -- the situation we had previously
with other autoload files. This change should mean that the necessity
for committing ldefs-boot.el is considerably reduced, since
ldefs-boot-auto.el depends on many fewer files than ldefs-boot.el, and
should mean that diffs are more accurate. It's a small advantage; not
having auto-generated files versioned is perhaps an obsession of mine.

The risk is that it will need more manual intervention. ldefs-boot-auto
is not a complete replacement for ldefs-boot.el. I only know which
autoloaded *functions* have been called. Other forms in autoload are not
captured and have been added manually

(defvar warning-series nil)
(defvar electric-pair-text-pairs '((34 . 34)))

both of which turn out (perhaps surprisingly) to be necessary for
bootstrap. My plan would be to code these dependencies out.
