This commit implements two optimizations when working with headers:
* Avoid having to explicitly "render" headers and separately store the
original casing for header names.
* Match special header names using a single regular expression instead
of testing one regular expression per header name.

This commit optimizes checkInvalidHeaderChar() by unrolling the
character checking loop a bit.
Additionally, some changes to the benchmark runner are needed in
order for the included benchmark to be run correctly. Specifically,
the regexp used to parse `key=value` parameters contained a greedy
quantifier that was causing the `key` to match part of the `value`
if `value` contained an equals sign.

This commit both makes checkIsHttpToken() inlinable and extracts
the character checking logic to a separate inlinable function so that
the main loop can be unrolled a bit.

Parsers hold a reference to the socket associated with the request
through onParserExecute. This must be removed when the parser is
freed so that the socket can be garbage collected when destroyed.

StreamBase instance").

Do not emit `upgrade` if the server is just advertising its protocols
support as per RFC 7230 Section 6.7.
A server MAY send an Upgrade header field in any other response
to advertise that it implements support for upgrading to the
listed protocols, in order of descending preference, when
appropriate for a future request.

This is a two-part fix:
- Fix pending data notification in `OutgoingMessage` to notify server
about flushed data too
- Fix pause/resume behavior for the consumed socket. `resume` event is
emitted on a next tick, and `socket._paused` can already be `true` at
this time. Pause the socket again to avoid PAUSED error on parser.

This adds a new check for header and trailer fields names and method
names to ensure that they conform to the HTTP token rule. If they do
not, a `TypeError` is thrown.
Previously this had an additional `strictMode` option that has been
removed in favor of making the strict check the default (and only)
behavior.
Doc and test case are included.
On the client-side
```javascript
var http = require('http');
var url = require('url');
var p = url.parse('http://localhost:8888');
p.headers = {'testing 123': 123};
http.client(p, function(res) { }); // throws
```
On the server-side
```javascript
var http = require('http');
var server = http.createServer(function(req,res) {
res.setHeader('testing 123', 123); // throws
res.end('...');
});

Many of the util.is*() methods used to check data types
simply compare against a single value or the result of
typeof. This commit replaces calls to these methods with
equivalent checks. This commit does not touch calls to the
more complex methods (isRegExp(), isDate(), etc.).

The copyright and license notice is already in the LICENSE file. There
is no justifiable reason to also require that it be included in every
file, since the individual files are not individually distributed except
as part of the entire package.
Make it a little harder to slip in use-after-free bugs by nulling out
references to the parser object after handing it off to freeParser().

Weak handles put strain on the garbage collector and the parser handle
doesn't need to be weak in the first place. This change should improve
GC times on busy servers a little.

The list of supported HTTP methods is available in JS land now so there
is no longer any need to pass a stringified version of the method to the
parser callback, it can look up the method name for itself.
Saves a call to v8::Eternal::Get() in the common case and a costly
v8::String::NewFromOneByte() in the uncommon case.
If a client sends a lot more pipelined requests than we can handle, then
we need to provide backpressure so that the client knows to back off.
Do this by pausing both the stream and the parser itself when the
responses are not being read by the downstream client.
