src: add node_internal.h includes for arraysize
This commit adds includes for node_internal.h in source files that use
arraysize but don't include this header. The motivation for this is to
make refactoring easier (and is the reason I noticed this).

src: clean up req.bytes tracking
Simply always tell the caller how many bytes were written, rather
than letting them track it.

In the case of writing a string, also keep track of the bytes
written by the earlier `DoTryWrite()`.

net: track bytesWritten in C++ land
Move tracking of `socket.bytesWritten` to C++ land.

This makes it easier to provide this functionality for all
`StreamBase` instances, and in particular should keep working
when they have been 'consumed' in C++ in some way (e.g. for
the network sockets that are underlying to TLS or HTTP2 streams).

Also, this parallels `socket.bytesRead` a lot more now.

src: tighten handle scopes for stream operations
Put `HandleScope`s and `Context::Scope`s where they are used,
and don’t create one for native stream callbacks automatically.

This is slightly less convenient but means that stream listeners
that don’t actually call back into JS don’t have to pay the
(small) cost of setting these up.

src: refactor WriteWrap and ShutdownWraps
Encapsulate stream requests more:

- `WriteWrap` and `ShutdownWrap` classes are now tailored to the
  streams on which they are used. In particular, for most streams
  these are now plain `AsyncWrap`s and do not carry the overhead
  of unused libuv request data.
- Provide generic `Write()` and `Shutdown()` methods that wrap
  around the actual implementations, and make *usage* of streams
  easier, rather than implementing; for example, wrap objects
  don’t need to be provided by callers anymore.
- Use `EmitAfterWrite()` and `EmitAfterShutdown()` handlers to
  call the corresponding JS handlers, rather than always trying
  to call them. This makes usage of streams by other C++ code
  easier and leaner.

Also fix up some tests that were previously not actually testing
asynchronicity when the comments indicated that they would.

src: minor refactoring to StreamBase writes
Instead of having per-request callbacks, always call a callback
on the `StreamBase` instance itself for `WriteWrap` and `ShutdownWrap`.

This makes `WriteWrap` cleanup consistent for all stream classes,
since the after-write callback is always the same now.

If special handling is needed for writes that happen to a sub-class,
`AfterWrite` can be overridden by that class, rather than that
class providing its own callback (e.g. updating the write
queue size for libuv streams).

If special handling is needed for writes that happen on another
stream instance, the existing `after_write_cb()` callback
is used for that (e.g. custom code after writing to the
transport from a TLS stream).

As a nice bonus, this also makes `WriteWrap` and `ShutdownWrap`
instances slightly smaller.

e71e71b513 http2: introducing HTTP/2
At long last: The initial *experimental* implementation of HTTP/2.

This is an accumulation of the work that has been done in the nodejs/http2
repository, squashed down to a couple of commits. The original commit
history has been preserved in the nodejs/http2 repository.

This PR introduces the nghttp2 C library as a new dependency. This library
provides the majority of the HTTP/2 protocol implementation, with the rest
of the code here providing the mapping of the library into a usable JS API.

Within src, a handful of new node_http2_*.c and node_http2_*.h files are
introduced. These provide the internal mechanisms that interface with nghttp
and define the `process.binding('http2')` interface.

The JS API is defined within `internal/http2/*.js`.

There are two APIs provided: Core and Compat.

The Core API is HTTP/2 specific and is designed to be as minimal and as
efficient as possible.

The Compat API is intended to be as close to the existing HTTP/1 API as
possible, with some exceptions.

Tests, documentation and initial benchmarks are included.

The `http2` module is gated by a new `--expose-http2` command line flag.
When used, `require('http2')` will be exposed to users. Note that there
is an existing `http2` module on npm that would be impacted by the introduction
of this module, which is the main reason for gating this behind a flag.

When using `require('http2')` the first time, a process warning will be
emitted indicating that an experimental feature is being used.

To run the benchmarks, the `h2load` tool (part of the nghttp project) is
required: `./node benchmarks/http2/simple.js benchmarker=h2load`. Only
two benchmarks are currently available.

Additional configuration options to enable verbose debugging are provided:

```
$ ./configure --debug-http2 --debug-nghttp2
$ NODE_DEBUG=http2 ./node
```

The `--debug-http2` configuration option enables verbose debug statements
from the `src/node_http2_*` files. The `--debug-nghttp2` enables the nghttp
library's own verbose debug output. The `NODE_DEBUG=http2` enables JS-level
debug output.

The following illustrates as simple HTTP/2 server and client interaction:

(The HTTP/2 client and server support both plain text and TLS connections)

```jt client = http2.connect('http://localhost:80');
const req = client.request({ ':path': '/some/path' });
req.on('data', (chunk) => { /* do something with the data */ });
req.on('end', () => {
  client.destroy();
});

// Plain text (non-TLS server)
const server = http2.createServer();
server.on('stream', (stream, requestHeaders) => {
  stream.respond({ ':status': 200 });
  stream.write('hello ');
  stream.end('world');
});
server.listen(80);
```

```js
const http2 = require('http2');
const client = http2.connect('http://localhost');

```

src: implement native changes for async_hooks
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.

30b7349176 stream_base: dispatch reqs in the stream impl
Dispatch requests in the implementation of the stream, not in the code
creating these requests. The requests might be piled up and invoked
internally in the implementation, so it should know better when it is
the time to dispatch them.

In fact, TLS was doing exactly this thing which led us to...

3d6440cf2a src: fix --without-ssl build
Don't include tls_wrap.h in stream_base.cc.  It's not used and it breaks
the build when --without-ssl is passed to configure.

Fixes the following build error:

    In file included from ../src/tls_wrap.h:5:0,
                     from ../src/stream_base.cc:10:

89e133a1d8 stream_base: remove static JSMethod declarations
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.

1738c77835 streams: introduce StreamWrap and JSStream
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()`.

b9686233fc stream_base: introduce StreamBase
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`.
