(srcdir, texinputdir): New variables.

(srcs, index.texi, install): Use $(srcdir).
(.PHONY): Remove elisp.dvi.
(elisp): Use -I switch for makeinfo.
(elisp.dvi): Use $(srcdir) and $(texinputdir).
(installall, dist): Use $(srcdir).
Fix path to texinfo.tex.
(maintainer-clean): Add elisp.dvi and elisp.oaux.
