Changes in the native code for the upcoming async_hooks module. These
have been separated to help with review and testing.
Changes include:
* Introduce an async id stack that tracks recursive calls into async
execution contexts. For performance reasons the id stack is held as a
double* and assigned to a Float64Array. If the stack grows too large
it is then placed in it's own stack and replaced with a new double*.
This should accommodate arbitrarily large stacks.
I'm not especially happy with the complexity involved with this async
id stack, but it's also the fastest and most full proof way of
handling it that I have found.
* Add helper functions in Environment and AsyncWrap to work with the
async id stack.
* Add AsyncWrap::Reset() to allow AsyncWrap instances that have been
placed in a resource pool, instead of being released, to be
reinitialized. AsyncWrap::AsyncWrap() also now uses Reset() for
initialization.
* AsyncWrap* parent no longer needs to be passed via the constructor.
* Introduce Environment::AsyncHooks class to contain the needed native
functionality. This includes the pointer to the async id stack, and
array of v8::Eternal<v8::String>'s that hold the names of all
providers, mechanisms for storing/retrieving the trigger id, etc.
* Introduce Environment::AsyncHooks::ExecScope as a way to track the
current id and trigger id of function execution via RAII.
* If the user passes --abort-on-uncaught-exception then instead of
throwing the application will print a stack trace and abort.

instead of creating own buffer, use MaybeStackBuffer on DoSend to
take advantage of its destructor to free up memory, so buffer
never leaks memory - even if code in DoSend throws.
Use MaybeStackBuffer in Writev to take advantage of destructor
on MaybeStackBuffer to clear itself up, rather than Writev managing
resources itself.

Set the `req.buffer` property, which serves as a way of keeping
a `Buffer` alive that is being written to a stream, on the C++
side instead of the JS side.
This closes a hole where buffers that were temporarily created
in order to write strings with uncommon encodings (e.g. `hex`)
were passed to the native side without being set as `req.buffer`.

When node began using the OneByte API (f150d56) it also switched to
officially supporting ISO-8859-1. Though at the time no new encoding
string was introduced.
Introduce the new encoding string 'latin1' to be more explicit. The
previous 'binary' and documented as an alias to 'latin1'. While many
tests have switched to use 'latin1', there are still plenty that do both
'binary' and 'latin1' checks side-by-side to ensure there is no
regression.

v8::Object::GetAlignedPointerFromInternalField() returns a random value
if Wrap() hasn't been run on the object handle. Causing v8 to abort if
certain getters are accessed. It's possible to access these getters and
functions during class construction through the AsyncWrap init()
callback, and also possible in a subset of those scenarios while running
the persistent handle visitor.
Mitigate this issue by manually setting the internal aligned pointer
field to nullptr in the BaseObject constructor and add necessary logic
to return appropriate values when nullptr is encountered.

Move JS methods to the stream_base-inl.h and thus define them on each
use of `StreamBase::AddMethods`. Inline `AddMethods` itself, so that
there won't be any need in a static declaration in stream_base.cc.
NOTE: This basically allows using this API in user-land, though, some
polishing is required before releasing it.

Introduce a way to wrap plain-js `stream.Duplex` streams into C++
StreamBase's child class. With such method at hand it is now possible to
pass `stream.Duplex` instance as a `socket` parameter to
`tls.connect()`.

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`.
