RFR(S) 8242142: convert clhsdb "class" and "classes" commands from javascript to java

[Chris Plummer]

Hello,

Please review the following:
https://bugs.openjdk.java.net/browse/JDK-8242142
http://cr.openjdk.java.net/~cjplummer/8242142/webrev.00/

See the CR for details. Note the output for the "class" command looks like:

    jdk/test/lib/apps/LingeredApp @0x0000000800bcb040

The output for "classes" is the same, except each class is listed. The 
output for "print <classaddr>" is kind of long, but includes the 
following line, which the test looks for to verify the "class" output.

    public class jdk.test.lib.apps.LingeredApp @0x0000000800bcb040

thanks,

Chris
