headers: Some trivial fixes for some documentation typos

Note also the willneed/will_need inconsistency. I guess it could be nice to ASAP
choose one of them and introduce a backward compatibility hack for the other.

The issues was mostly found with:
for a in $(grep -r '^[ /]\*.*()' $(
	find -name '*.[ch]') |
	sed 's,^.* \([^ ]*\)().*$,\1,g' |
	sort |
	uniq |
	grep ^pa_)
do
	grep -rq "^.[^*].*\<$a(" $(find * -name '*.h') || echo $a
done
