RFR [12] 8213490: Networking area nano cleanup

[Pavel Rappo]

Hello,

Please review the following change:

  http://cr.openjdk.java.net/~prappo/8213490/webrev.00

This change is all about typos in javadoc, variables' names and comments. Once
again, not only does this change addresses aesthetic issues, it also helps with
searches.

As always with this type of change I recommend importing the changeset and
having a look at it with a diff tool that provides a character-level resolution.
Not using a webrev. Otherwise you are at risk of staring at line-level diffs for
too long, trying to pinpoint the change.

Among others there is a particular change in Inet6Address.java that reflects
the fact that [draft-ietf-ipngwg-scoping-arch-04] [1] has expired. As far as I
can see it's been superseded by a real RFC [2].

Thanks,
