RFR: 7166687: InetAddress.getLocalHost().getHostName() returns FQDN

[Rob McKenna]

Hi folks,

A typo in the MacOSX work led to a regression in b11 of 7u4. Specifically:

http://hg.openjdk.java.net/jdk7u/jdk7u/jdk/diff/5cca2f1a37da/src/solaris/native/java/net/Inet6AddressImpl.c

As per the bug report the && in the 2nd #if macro meant that this 
condition was ignored and the solaris code was used instead. I.e. 
getnameinfo to was used to do the lookup whereas Linux previously used 
gethostname with the effect that a call to 
InetAddress.getLocalHost().getHostName() now returned the fqdn instead 
of the hostname alone.

webrevs for 7 & 8 (identical): http://cr.openjdk.java.net/~robm/7166687/
