=head2 getfamilybyname

   $family = IO::Async::OS->getfamilybyname( $name )

Return a protocol family value based on the given name. If C<$name> looks like
a number it will be returned as-is. The string values C<inet>, C<inet6> and
C<unix> will be converted to the appropriate C<AF_*> constant.

Will pack an IP address and port number from keys called C<ip> and C<port>.
If C<ip> is missing it will be set to "::". If C<port> is missing it will be
set to 0. Optionally will also include values from C<scopeid> and C<flowinfo>
keys if provided.

This will only work if a C<pack_sockaddr_in6> function can be found in
C<Socket>

aliased as simply C<getaddrinfo>.

The C<getaddrinfo_array> resolver behaves more like the C<Socket6> version of
the function. It takes hints in a flat list, and mangles the result of the
function, so that the returned value is more useful to the caller. It splits
up the list of 5-tuples into a list of ARRAY refs, where each referenced array
contains one of the tuples of 5 values.

As an extra convenience to the caller, both resolvers will also accept plain
string names for the C<family> argument, converting C<inet> and possibly
C<inet6> into the appropriate C<AF_*> value, and for the C<socktype> argument,
converting C<stream>, C<dgram> or C<raw> into the appropriate C<SOCK_*> value.

The C<getnameinfo> resolver returns its result in the same form as C<Socket>.

Because this module simply uses the system's C<getaddrinfo> resolver, it will
be fully IPv6-aware if the underlying platform's resolver is. This allows
programs to be fully IPv6-capable.
