Perflib is used when processing the heap dump to populate the\ninformation initially, but afterwards all views and handlers go\nthrough the new com.android.ahat.heapdump API.\n\nThe primary motivation for this change is to facilitate adding support\nfor diffing two heap dumps to ahat. The new API provides flexibility\nthat will make it easier to form links between objects in different\nsnapshots and introduce place holder objects to show when there is an\nobject in another snapshot that has no corresponding object in this\nsnapshot.\n\nA large number of test cases were added to cover missing cases\ndiscovered in the process of refactoring ahat\u0027s perflib API.\n\nThe external
