JDK-8156680: jdeps implementation refresh
JDK-8153042: jdeps should continue to report JDK internal APIs that are removed/renamed in JDK 9

Webrev at:
   http://cr.openjdk.java.net/~mchung/jdk9/webrevs/8156680/webrev.00/

This refactors the jdeps implementation that regression tests can be developed without the need to parse the output file.  It also includes a list of the removed JDK internal APIs and provides the pointer where to look for more further information.

JDK-8153481: tools/jdeps/modules/GenModuleInfo.java and ModuleTest.java fails intermittently
