2da7d9b820 http2: near full http1 compatibility, add tests
Extensive re-work of http1 compatibility layer based on tests in
express, on-finished and finalhandler. Fix handling of HEAD
method to match http1. Adjust write, end, etc. to call writeHead
as in http1 and as expected by user-land modules. Add socket
proxy that instead uses the Http2Stream for the vast majority of
socket interactions. Add and change tests to closer represent
http1 behaviour.

bc23681aa2 http2: small fixes to compatibility layer
Expand argument validation through compat API, adjust behaviour
of response.end to not throw if stream already closed to match
http1, adjust behaviour of writeContinue to not throw if stream
already closed and other very small tweaks. Add tests for added
and fixed behaviour. Add tests for edge case behaviours of
setTimeout, createPushResponse, destroy, end and trailers.

641646463d http2: add compat trailers, adjust multi-headers
Adds Http2ServerRequest trailers & rawTrailers functionality. Also fixes
behaviour of multi-headers to conform with the spec (all values but
set-cookie and cookie should be comma delimited, cookie should be
semi-colon delimited and only set-cookie should be an array). Adds
setter for statusMessage that warns, for backwards compatibility.
End readable side of the stream on trailers or bodyless requests

800c32d315 http2: fix closedCode NaN, increase test coverage
[kFinish](code) can be triggered from a 'finish' event (for example
when calling response.end) which does not pass code. That tries to
set closedCode to undefined resulting in NaN closedCode instead of
NGHTTP2_NO_ERROR. Check for code !== undefined before setting.
Adds tests for closed and closedCode.

ad3d2ce68a http2: handle 100-continue flow & writeContinue
Adds an implementation for writeContinue based on the h2 spec & the
existing http implementation. ClientHttp2Stream now also emits
a continue event when it receives headers with :status 100.
Includes two test cases for default server continue behaviour and
for the exposed checkContinue listener.

53c5bf546e http2: refactor error handling
This changes the error handling model of ServerHttp2Stream,
ServerHttp2Request and ServerHttp2Response.
An 'error' emitted on ServerHttp2Stream will not go to
'uncaughtException' anymore, but to the server 'streamError'.
On the stream 'error', ServerHttp2Request will emit 'abort', while
ServerHttp2Response would do nothing.
It also updates respondWith* to the new error handling.

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');

```
