bug#21563: 24.5; discourage load-hook variables

[Roland Winkler]

Somewhere in my emacs init file I was setting the variable
dired-load-hook.  (I guess I wrote this code years ago when I did
not know much about emacs.)  Yet suddenly this did not work for me
anymore, as I had rearranged my init file so that dired got loaded
before I was setting dired-load-hook.  I suggest to discourage the
usage of any such load-hook variables: I believe eval-after-load is
considered to be the cleaner alternative: it does not give rise to
the type of problems I ran into.  Also it does not require user
variables for each package.

(Apropos gives me the variables align-load-hook, cal-menu-load-hook,
calendar-load-hook, dired-load-hook, ediff-load-hook, and
table-load-hook.  There might be more.)
