Without actually trying it - seemed like a good idea; however, the 
virSocketAddrParse uses/sets "hints.ai_flags = AI_NUMERICHOST;" thus
it requires a numeric value and not one that could be a name or a
number, so it seems this particular code cannot use it.

I really see those virSocketAddr* API's as different, very specific
to supporting the network socket's and socket address formats; whereas,
this code will take a string representation of either the name or
the number as provided in the XML and validate it.

I don't think this set of API's belongs there as it's not manipulating

So, I'll change the function intro to:

 * Unlike virGetHostname, this variant of the code receives a hostname and
 * retrieves the getaddrinfo. If the passed hostname can be successfully
 * resolved via getaddrinfo, then return true; otherwise, if the hostname
 * cannot be resolved for any reason, return false.


remove the localhost specific checking

and adjust the commit message to remove the 'getnameinfo' reference.
