RFR(M): JDK-8165805 - [TESTBUG] CDS needs to support JVMTI CFLH - test development

[Mikhailo Seledtsov]

     Please review the tests that accompany the changes for
     "JDK-8078644 - CDS needs to support JVMTI CFLH"

     The tests include several test cases that are produced by combination
     of transforming related classes: super/sub class and 
interface/implementor.
     The classes reside in CDS archive. Tests check to ensure that correct
     transformation is performed, classes are loaded from the archive 
only when appropriate,
     and that test process using the archive completes w/o errors/crashes.


     Details:

     The main class is TransformRelatedClasses.java; start review with 
this class.
     Other classes are:
       - TransformSuperAndSubClasses.java, 
TransformInterfaceAndImplementor.java
         the "actual tests", but really just test headers calling into 
TransformRelatedClasses.java

       - TransformTestCommon.java - common methods for transformation tests

       - TestEntry.java - an entry into combinatorial test table 
representing a single test case

       - CDSTestUtils.java, TransformUtil.java - utility classes that 
are common  CDS
         tests

       - TransformerAgent.java - agent that performs transformation 
(comes with .mf file)

     Testing:
         Ran these tests on a standard set of platforms thru automated 
test system.
