1 is actually a valid flag on SmartOS. More generally, hints flags'
values are defined by the underlying native flags, and these can have
different values on different systems.
Using (ADDRCONFIG | V4MAPPED) + 1 ensure that the flag will be invalid,
since it will always be different from ADDRCONFIG, V4MAPPED, ADDRCONFIG
| V4MAPPED, 0 and any other combination of even flags.

Currently the address resolution family defaults to IPv4. Instead remove
the preference and instead resolve to a family suitable for the host.
Expose the getaddrinfo flags and allow them to be passed.
Add documentation about new flags.

Don't use argument as callback if it's not a valid callback function.
Throw a valid exception instead explaining the issue.
Adds to #7070 ("DNS — Throw meaningful error(s)").
getServers returns an array of ips that are currently being used for
resolution
setServers takes an array of ips that are to be used for resolution,
this will throw if there's invalid input but preserve the original
configuration
A typo in the variable name makes it throw a ReferenceError instead of
the expected "Unknown type" error when dns.resolve() is passed a bad
record type argument.
Fixes the following exception:
ReferenceError: type is not defined
