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');
```

Commit c5b07d4 ("lib: fix beforeExit not working with -e") runs the
to-be-evaluated code at a later time than before because it switches
from `process.nextTick()` to `setImmediate()`.
It affects `-e 'process.on("message", ...)'` because there is now a
larger time gap between startup and attaching the event listener,
increasing the chances of missing early messages. I'm reasonably
sure `process.nextTick()` was also susceptible to that, only less
pronounced.
Avoid the problem altogether by evaluating the code synchronously.
Harmonizes the logic with `Module.runMain()` from lib/module.js
which also calls `process._tickCallback()` afterwards.

Commit 93a44d5 ("src: fix deferred events not working with -e") defers

A side effect of that change is that 'beforeExit' listeners run before

empty but process.nextTick() does not ref the event loop.
Fix that by using setImmediate(). Because it is implemented in terms

This has the effect that builtins modules which could not be loaded

In several places throughout the code we write directly to stderr
to report warnings (deprecation, possible eventemitter memory leak).
The current design of simply dumping the text to stderr is less
than ideal. This PR introduces a new "process warnings" mechanism
that emits 'warning' events on the global process object. These are
invoked with a `warning` argument whose value is an Error object.
By default, these warnings will be printed to stderr. This can be
suppressed using the `--no-warnings` and `--no-deprecation` command
line flags. For warnings, the 'warning' event will still be emitted
by the process, allowing applications to handle the warnings in custom
ways. The existing `--no-deprecation` flag will continue to supress
all deprecation output generated by the core lib.
The `--trace-warnings` command line flag will tell Node.js to print
the full stack trace of warnings as part of the default handling.
The existing `--no-deprecation`, `--throw-deprecation` and
`--trace-deprecation` flags continue to work as they currently do,
but the exact output of the warning message is modified to occur
on process.nextTick().
The stack trace for the warnings and deprecations preserve and point
to the correct call site.
A new `process.emitWarning()` API is provided to permit userland
to emit warnings and deprecations using the same consistent
mechanism.
Test cases and documentation are included.
