StreamBase is an improved way to write C++ streams. The class itself is
for separting `StreamWrap` (with the methods like `.writeAsciiString`,
`.writeBuffer`, `.writev`, etc) from the `HandleWrap` class, making
possible to write abstract C++ streams that are not bound to any uv
socket.
The following methods are important part of the abstraction (which
mimics libuv's stream API):
* Events:
* `OnAlloc(size_t size, uv_buf_t*)`
* `OnRead(ssize_t nread, const uv_buf_t*, uv_handle_type pending)`
* `OnAfterWrite(WriteWrap*)`
* Wrappers:
* `DoShutdown(ShutdownWrap*)`
* `DoTryWrite(uv_buf_t** bufs, size_t* count)`
* `DoWrite(WriteWrap*, uv_buf_t*, size_t count, uv_stream_t* handle)`
* `Error()`
* `ClearError()`
The implementation should provide all of these methods, thus providing
the access to the underlying resource (be it uv handle, TLS socket, or
anything else).
A C++ stream may consume the input of another stream by replacing the
event callbacks and proxying the writes. This kind of API is actually
used now for the TLSWrap implementation, making it possible to wrap TLS
stream into another TLS stream. Thus legacy API calls are no longer
required in `_tls_wrap.js`.

The current implementation uses the arguments object in the Server()
constructor. Since both arguments to Server() are optional, there was a

carries a performance overhead. This commit replaces the arguments

In cases where many small writes are made to a stream
lacking _writev, the array data structure backing the
WriteReq buffer would greatly increase GC pressure.
Specifically, in the fs.WriteStream case, the
clearBuffer routine would only clear a single WriteReq
from the buffer before exiting, but would cause the
entire backing array to be GC'd. Switching to [].shift
lessened pressure, but still the bulk of the time was
spent in memcpy.
This replaces that structure with a linked list-backed
queue so that adding and removing from the queue is O(1).
In the _writev case, collecting the buffer requires an
O(N) loop over the buffer, but that was already being
performed to collect callbacks, so slowdown should be
neglible.

Windows and Unix return certain socket errors (i.e. EADDRINUSE) at
different times: bind on Windows, and listen on Unix.
In an effort to hide this difference, libuv on Windows stores such
errors in the bind_error field of uv_tcp_t, to defer raising it at
listen time.
This worked fine except for the case in which a socket is shared in
a Node cluster and a bind error occurs.
A previous attempt to fix this (
d1e6be14603da36fe00e

it caused the master to start accepting connections.
With this new approach, libuv itself is relaying the bind errors,
providing for a uniform behavior of uv_tcp_listen.
