Summary:
   This round includes the changes suggested by Alan in the round #0:
     - The version 1.9 is replaced version
     - The Module interface is replaced with the ModuleReference 
interface that extends the ObjectReference.
     - The argument name "target" in the CanRead is replaced with 
"source" to make it consistent with
        the class java.lang.reflect.Module.
     - The public field TRACE_MODULES has been removed.
     - Some other small changes.

    This round also addresses the suggestions from Alan in the review 
round #1:
     - new capability "can_get_modules_info" is defined on the JDI level 
only;
       changed the capability name: "canGetModulesInfo" => 
"canGetModuleInfo"
     - JVMTI doc cleanup: minor corrections, removed couple of 
references to the JDK 1.1, spurious <UL>'s
     - copyright fixes
     - test improvements

This fix includes JVMTI support for the JDI allModules() as a JVMTI 
function GetAllModules().
   There is an agreement with Lois this will most likely need some 
future adjustment.
