This improves dgram performance by avoiding unnecessary async
operations.
One issue with this commit is that it seems hard to actually create
conditions under which the fallback path to the async case is
actually taken, for all supported OS, so an internal CLI option
is used for testing that path.
Another caveat is that the lack of an async operation means
that there are slight timing differences (essentially `nextTick()`
rather than `setImmediate()` for the send callback).

Added the `dgram.connect()` and `dgram.disconnect()` methods that
associate/disassociate a udp socket to/from a remote address.
It optimizes for cases where lots of packets are sent to the same
address.
Also added the `dgram.remoteAddress()` method to retrieve the associated
remote address.

For TCP servers, the dual-stack support is enable by default, i.e.
binding host "::" will also make "0.0.0.0" bound. This commit add
ipv6Only option in `net.Server.listen()` and `dgram.createSocket()`
methods which allows to disable dual-stack support. Support for
cluster module is also provided in this commit.

It seems the property socket.fd is used long before for the
compatibility reason but it's not used anymore. It's also
not documented in docs so that it's not a public api/property.
Keep the property also make the code a bit confusing as
socket._handle.fd is the actual property representing fd.

This commit improves the SystemError messages by allowing user
to combine a custom message and the libuv error message. Also
since we now prefer use subclasses to construct the errors instead
of using `new errors.SystemError()` directly, this removes
the behavior of assigning a default error code `ERR_SYSTEM_ERROR`
to SystemError and requires the user to directly use the
`ERR_SYSTEM_ERROR` class to construct errors instead.
Also merges `makeNodeError` into the SystemError class definition
since that's the only place the function gets used and it seems
unnecessary to introduce another level of inheritance. SystemError
now directly inherits from Error instead of an intermmediate Error
class that inherits from Error.
Class hierarchy before this patch:
ERR_SOCKET_BUFFER_SIZE -> Error (use message formatted by SystemError)
ERR_SYSTEM_ERROR -> NodeError (temp) -> Error
After:
ERR_SOCKET_BUFFER_SIZE -> SystemError -> Error
ERR_TTY_INIT_FAILED -> SystemError -> Error
ERR_SYSTEM_ERROR -> SystemError -> Error
Error messages before this patch:
```
const dgram = require('dgram');
const socket = dgram.createSocket('udp4');
socket.setRecvBufferSize(8192);
// Error [ERR_SOCKET_BUFFER_SIZE]: Could not get or set buffer
// size: Error [ERR_SYSTEM_ERROR]: bad file descriptor:
// EBADF [uv_recv_buffer_size]
// at bufferSize (dgram.js:191:11)
// at Socket.setRecvBufferSize (dgram.js:689:3)

new tty.WriteStream(1 << 30);
// Error [ERR_SYSTEM_ERROR]: invalid argument: EINVAL [uv_tty_init]
// at new WriteStream (tty.js:84:11)

This makes a effort to make sure all of these errors will actually
also show the received input.
On top of that it refactors a few tests for better maintainability.
It will also change the returned type to always be a simple typeof
instead of special handling null.

Instead of exposing internals of async_hooks & async_wrap throughout
the code base, create necessary helper methods within the internal
async_hooks that allows easy usage by Node.js internals. This stops
every single internal user of async_hooks from importing a ton of
functions, constants and internal Aliased Buffers from C++ async_wrap.
Adds functions initHooksExist, afterHooksExist, and destroyHooksExist
to determine whether the related emit methods need to be triggered.
Adds clearDefaultTriggerAsyncId and clearAsyncIdStack on the JS side
as an alternative to always calling C++.
Moves async_id_symbol and trigger_async_id_symbol to internal
async_hooks as they are never used in C++.
Renames newUid to newAsyncId for added clarity of its purpose.
Adjusts usage throughout the codebase, as well as in a couple of tests.

This commit moves error creation helpers scattered around
under lib/ into lib/internal/errors.js in the hope of being clearer
about the differences of errors that we throw into the user land.
- Move util._errnoException and util._exceptionWithHostPort
into internal/errors.js and simplify their logic so it's
clearer what the properties these helpers create.
- Move the errnoException helper in dns.js to internal/errors.js
into internal/errors.js and rename it to dnsException. Simplify
it's logic so it no longer calls errnoException and skips
the unnecessary argument checks.

The existing version of defaultTriggerAsyncIdScope creates an Array
for the callback's arguments which is highly inefficient. Instead,
use rest syntax and allow V8 to do that work for us. This yields
roughly 2x performance for this particular function.

Previously the getter would mutate the kDefaultTriggerAsncId value. This
refactor changes the setter to bind the current kDefaultTriggerAsncId to
a scope, such that the getter doesn't have to mutate its own value.
