btw I'd really prefer not to use the code from Net::DNS::Resolver -- look at it,
it's terrifying!  let's just use IO::Socket::INET6 and keep it simple.

having said that, yes, I meant to fix the bgsend case and it looks like I
forgot.  it's harmless -- IO::Socket::INET6 and ::INET do the right thing afaik
-- but it's unclear.

basically, with UDP sockets you have two choices:

  1. specify the dest endpoint in the IO::Socket::INET constructor, or
  2. specify it at send() time

that works for IPv4, and #2 is what we were using in Resolver.  However, for
IPv6 with IO::Socket::INET6, only #1 works, #2 seems to be no longer supported.
 therefore we have to change our code to use the #1 approach instead of #2. 
Since we only ever used 1 endpoint anyway, this is no biggie for us anyway.
