It appears that either c-ares no longer calls callbacks synchronously
or we have since explicitly taken care of the scenarios in which
c-ares would call callbacks synchronously (e.g. resolving an IP
address or an empty hostname). Therefore we no longer need to have
machinery in place to handle possible synchronous callback invocation.
This improves performance significantly.

Currently we use `{}` for the `lookup` function to find the relevant
resolver to the dns.resolve function. It is preferable to use an
object without a Object.prototype, currently for example you can do
something like:
```js
dns.resolve("google.com", "toString", console.log);
```
And get `[Object undefined]` logged and the callback would never be
called. This is unexpected and strange behavior in my opinion.
In addition, if someone adds a property to `Object.prototype` might
also create unexpected results.
This pull request fixes it, with it an appropriate error is thrown.

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)").
Removing a hack intended to shortcut the resolution of 'localhost'
but which doesn't work for ipv6.
This was introduced in 2876141c42.
However it seems that the problems that this was trying to
circumvent has gone away ages ago, when dns resolution on
Windows started relying on Win32 GetAddrInfoW, which was
probably with be2320d408.
Fixes test-net-connect-options-ipv6.js on Windows.
A follow-up commit will save the domain name on the request object but
we can't call that property 'domain' because that gets intercepted by
src/node.cc and lib/domain.js to implement the node.js feature of the
same name.
To avoid confusion, rename all variables called 'domain' to 'hostname'.
The test case from the previous commit exposed a regression in the way
that c-ares errors are reported to JS land. Said regression was
introduced in commit 756b622 ("src: add multi-context support").
Fixes the following test failure:
$ out/Release/node test/simple/test-dns-regress-6244
util.js:675
var errname = uv.errname(err);
^
Error: err >= 0
at Object.exports._errnoException (util.js:675:20)
at errnoException (dns.js:43:15)
at Object.onresolve [as oncomplete] (dns.js:145:19)
lib/dns.js erroneously assumed that the error code was a libuv error
code when it's really a c-ares status code. Libuv handles getaddrinfo()
style lookups (which is by far the most common type of lookup), that's
why this bug wasn't discovered earlier.
Don't set the oncomplete property in src/cares_wrap.cc, we can do it
just as easily in lib/dns.js.
Switch two closures to the 'function with _this_ object' model. Makes
it impossible for an overzealous closure to capture too much context
and accidentally hold on to too much memory.
Libuv now returns errors directly. Make everything in src/ and lib/
follow suit.
The changes to lib/ are not strictly necessary but they remove the need
for the abominations that are process._errno and node::SetErrno().
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

at /Users/bnoordhuis/src/master/test/simple/test-c-ares.js:48:9
<snip>
- [lib/dns.js] dns.lookup takes a new optional argument "family" which
should be the integer 4, 6, dns.AF_INET or dns.AF_INET6. Passing a
non-false "family" argument makes c-ares explicitly look up addresses for
the specified family.
- [test/simple/test-c-ares.js] test explicit address family lookups
C-Ares doesn't go through the Name Service Switch (NSS) and thus can't
resolve certain classes of names. Generally this doesn't matter and the
whole idea of NSS is rather annoying. Nevertheless until C-Ares gets better
support, adding this hack to go through getaddrinfo() for .local domain look
up.
This reverts commit 9926dacd14.
