    vos: GetServer search for non-loopback address
    
    GetServer() is used to obtain an IP address for the 'aname' parameter.
    'aname' can be either a dotted address or a host name.   If it is a dotted
    address, it is returned immediately.  If it is a host name, then
    gethostbyname() is used to obtain an IP address.
    
    The prior version of this function had two failings:
    
    1. It assumed that a struct hostent only contained a single address.
       It used the former h_addr field.  For all platforms supported by
       OpenAFS h_addr is a macro referencing the first address in the
       h_addr_list array.  If h_addr was a loopback address, it would
       ignore any additional addresses that might be in the list.
    
    2. It assumed that if gethostbyname(aname) returned a loopback
       address as h_addr that 'aname' must be referring to the machine
       that the vos command is being executed on.  It therefore used
       gethostname() to obtain an alternate name to use for a gethostbyname()
       query.  The results of this query were not checked to be a loopback.
       As a result, a loopback address could be returned to the caller which
       in turn could be set into the VLDB.
