configure: add mips-float-abi (soft, hard) option
tls: fix setting NPN protocols

The NPN protocols was set on `require('tls')` or `global` object instead
of being a local property. This fact lead to strange persistence of NPN
protocols, and sometimes incorrect protocol selection (when no NPN
protocols were passed in client options).

fix #6168
doc: fix blog link in blog posts and README

Apparently Joyent decommissioned joyeur.com but at least they saved the
contents of the blog.  Update the links in the README and the nodejs.org
blog posts.

Hat tip to Eugen Pirogoff (@eugenpirogoff) for pointing it out.

Fixes #6224.
tls: don't push() incoming data when ondata is set

Otherwise the data ends up "on the wire" twice, and
switching between consuming the stream using `ondata`
vs. `read()` would yield duplicate data, which was bad.
doc: specify the format of the `ca` tls option
doc: fix typos in the tls `NPNProtocols` option
doc: document reserved status of SIGUSR1

Fixes #1212.
readline: handle input starting with control chars

Handle control characters only when there is a single byte in the
stream, otherwise fall through to the standard multibyte handling.
tls: wrap tls inside tls using legacy API

Allow wrapping TLSSocket inside another TLSSocket, emulate it using
SecurePair in legacy APIs.

fix #6204
Revert "deps: update v8 to 3.20.17.11"

After the upgrade from 3.20.17.7 to 3.20.17.11, we've begun hitting
random assertions in V8 in memory-constrained / GC-heavy situations.

The assertions all seem to be related to heap allocations and garbage
collection but apart from that, they're all over the place.

This reverts commit 970bdccc38fee27e10ff1a3b68f3fea3417788a1.

src: remove ObjectWrap dependency from core

Drop the ObjectWrap dependency in favor of an internal WeakObject class.

Let's us stop worrying about API and ABI compatibility when making
changes to the way node.js deals with weakly persistent handles
internally.
