The javac tool now provides the ability to generate native headers as needed. This removes the need to run the javah tool as a separate step in the build pipeline. The feature is enabled in javac by using the new -h option, which is used to specify a directory in which the header files should be written. Header files will be generated for any class which has either native methods, or constant fields annotated with a new annotation of type java.lang.annotation.Native. (Since JDK 1.8)
This should ease the transition to a modular build by allowing us to remove one extra javah step.
These two change sets add @Native annotations to classes that we need in native that are not currently being generated automatically with javac -h. In two cases, I removed "empty" header includes (the javah generated header does not have any meaningful content).

Note that the actual conversion to using the javac -h step will happen at a later date. These changesets just allow us to get ready for that future, and reduce the risk of merge conflicts later.
