Fix functions that were unused (getJsDocComments), redundant (append) or badly named
(getJSDocCommentsFromText)

Yeah, that name is way too long.

1. Get rid of parent check.
2. Use a couple of nested functions, one of them a recursive worker.

And delete its near-duplicate which was much less correct. The callers
that had to switch are slightly more complex and more correct now.

Cache only uses one property now. getJSDocs isn't generic and doesn't
take a function parameter any more. The code is overall easier to read.
