[8u] RFR Backport JDK-8154313, Generated javadoc scattered all over the place

[Jiri Vanek]

hi!

This is third, hopefully last, reincarnation of this backport.
Refreshed - http://cr.openjdk.java.net/~jvanek/8154313/ - as it was approved last time.
It is  jdk11-like version of the patch.

However after above was agreed, an issue concerning backport of
https://bugs.openjdk.java.net/browse/JDK-8168772 (
http://hg.openjdk.java.net/jdk9/jdk9/rev/db49e4e492e0 ), which is quite huge was raised.

If there is no intention to backport 8168772  ever, then my current patch is good to go. If not,
then the 8154313 (http://hg.openjdk.java.net/jdk9/jdk9/rev/ec69c5bf68a6) should be applied as it was
commited, but 8168772 have to follow after it.
I do not feel exactly voulenteered ino backporting of 8168772

Thanx!
  J.
