Merge r27122 from nmap-npingchanges: Changed names for output funtions. outPrint() -> nping_print(); outFatal() -> nping_fatal() ; outError() -> nping_warning(). This change is completely irrelevant but I personally hate the names I chose the first time and I thought I'd change them to something better.
Merge r27120,27121,27123,27124,27125 from nmap-npingchanges. Minor style and typo fixes.
