RFR: 8145461 changes to @Deprecated annotation

[Stuart Marks]

Hi all,

Please review these changes to the @Deprecated annotation:

     http://cr.openjdk.java.net/~smarks/reviews/8145461/webrev.0/

This is the first of a set of changes for JEP 277, which I hope will become 
Targeted to JDK 9 late this week. Changes to the deprecation status of specific 
APIs will be in subsequent changesets, along with some deprecation tooling.

Note that this is considerably simplified from previous drafts. In particular, 
there is no "reason" enum. See the JEP [1] for background and rationale.

Thanks,

s'marks
