(font-lock-default-fontify-buffer): Try and set-defaults even if font-lock-mode

is non-nil since it may be t without having turned on font-lock-mode-internal.
(font-lock-choose-keywords): Minor optimization.
(font-lock-add-keywords, font-lock-remove-keywords, font-lock-set-defaults):
Don't call make-local-variable on a variable that we know to already be local.
