Compiler folk, build folk, Please review this update for javac and some build files, for JEP 277.
The work supports the enhanced Deprecation attribute, and generates a new warning when items are referenced that are declared with @Deprecated(forRemoval=true), in line with the proposals in JEP 277.
The warnings are on by default, and can be suppressed with -Xlint:-removal or @SuppressWarnings("removal"). Because the warnings are on by default, and because the warnings currently show up when building JDK, some minor build changes are temporarily required to suppress the warnings that get generated during the build.
