8000362: (pack200) Deprecate Packer/Unpacker addPropertyChangeLister and removePropertyChangeListener methods

[Alan Bateman]

This is a follow-on from yesterday's mail on deprecating the 
LogManager's add/removePropertyChangeListener methods. The other 4 
problematic methods identified in JEP 162 [1] are the same name methods 
on Pack200.Packer and Pack200.Unpacker. The webrev to deprecate these 
methods is here:

As with the LogManager methods, Mandy Chung searched >20000 projects. In 
this case we didn't find any usages of these methods and this gives us 
confidence that these methods are rarely used. We don't propose to 
provide a replacement for these methods but instead just include wording 
to suggest that applications poll the value of the progress property if 
they really need to provide some progress indication.

Kumar is the pack200 guru here and I know he's busy/away at the moment 
so I plan to hold onto this patch until I at least hear from him.
