RFR JDK-8187485: Update Zip implementation to use Cleaner, not finalizers

[Xueming Shen]

Hi

Please review the revision to the change for

JDK-8187485: Update Zip implementation to use Cleaner, not finalizers

For compatibility with previous jdk releases, in this proposed revision 
the corresponding
close()/end() methods will be called when the ZipFile/Inflater/Deflater 
object has become
unreachable, if the ZipFile/Inflater/Deflater has been subclassed and 
its close()/end() method
has been overridden. In this case, the finalization mechanism is used to 
clean up the underlying
resources.  If the ZipFile/Inflater/Deflater has not been subclassed OR 
the corresponding
close()/end() method has not been overridden, then the Cleaner mechanism 
is used to do
the cleanup.
