Please review this simple fix for two related aspects of the same problem:
Export the "standard doclet" used by javadoc, such that it is possible
to derive alternative doclets, either by delegation or subtyping.
In JDK 9, javadoc has a "new" standard doclet (JEP 221), but the old one
remains for compatibility, for the time being. Both should be exported.
Jigsaw folk:
Please review the changes to jdk.javadoc module-info.
Build folk:
The javadoc documentation is extended to include the documentation
for the package containing the new StandardDoclet.
(The API for the old StandardDoclet was never published in this
manner; it is only included in the javadoc tool guide, which remains
unchanged, for now.)
javadoc folk:
The top level class for the new StandardDoclet is moved, without
any functional change, from an internal package to the new exported package.
