RFR: 7146564 DefaultProxySelector should filter 0.0.0.0 and ::0 [macosx]

[Michael McMahon]

Could I get the following webrev reviewed please for 7u4?

Something I overlooked in the recent change to the DefaultProxySelector
is that some of our tests end up trying to connect to 0.0.0.0
and that needs to be added to the default proxy list.

There are a couple of other test failures related to this
which the change fixes.

Thanks
Michael
