[Adam Domurad]

The unit test infrastructure + tests:
2012-12-XX  Adam Domurad  <adomurad at redhat.com>

     * tests/cpp-unit-tests/browser_mock.cc
     (mock_retainobject): New, mocks behaviour of NPAPI retainobject
     (mock_releaseobject): New, mocks behaviour of NPAPI releaseobject
     * tests/cpp-unit-tests/main.cc: Add warning of memory leak based on
     operator-new.
     * tests/cpp-unit-tests/IcedTeaScriptablePluginObjectTest.cc: New, tests
     for memory leak in (IcedTeaScriptableJavaObject::deAllocate) and
     (IcedTeaScriptableJavaPackageObject::deAllocate)
     * tests/cpp-unit-tests/checked_allocations.h: Defines set that does not
     use operator-new, to prevent recursion in overloaded operator-new
     * tests/cpp-unit-tests/checked_allocations.cc: Operator new overload
     that has allocation-set for querying live allocations.

The fix:
2012-12-XX  Adam Domurad  <adomurad at redhat.com>

     * plugin/icedteanp/IcedTeaScriptablePluginObject.cc
     (IcedTeaScriptableJavaObject::deAllocate): Fix memory leak
     (IcedTeaScriptableJavaPackageObject::deAllocate): Fix memory leak
