Andrew Nacin 50cd56f8fd Clarify the return value of has_filter() and has_action(). It returns a boolean if only the first argument is specified. If the second argument is specified, it returns false or an integer, which means it may return a non-boolean value that evaluates to false (so, 0), so you should take care to use the === operator. ...

Correct the function definition of remove_filter() and remove_action(), which 'accepted' an $accepted_args argument, but did not require or use it.

fixes #19417.
