* help-fns.el (help-fns-describe-function-functions): New variable to
call functions for augmenting help buffers.
(describe-function-1): Remove explicit calls to
`help-fns--compiler-macro', `help-fns--parent-mode' and
`help-fns--obsolete'.  Put them in above new variable instead.  Call
all of them through `run-hook-with-args'.
