bug#14974: 24.3.50; adaptive-wrap 0.3 calls potentially void function easy-menu-add-item

[Sebastian Wiesner]

adaptive-wrap 0.3 adds an autoload for a call to "(easy-menu-add-item
…)".  However, "easy-menu-add-item" itself is not autoloaded, and
"adaptive-wrap" does not "(require 'easymenu)" before calling
"easy-menu-add-item" in an autoload.

Hence, *activating* (not even loading!) "adaptive-wrap" fails unless
"easymenu" incidentally happens to be loaded before.

Obviously this breaks all sorts of things, most notably package
installation in "emacs -Q --batch".
