deps: update v8 to 3.24.35.17
headers: remove env.h from node_internals.h

`env.h` is an internal header file and should not be copied or exposed
to the users.

Additionally, export convenience `Throw*` methods with `v8::Isolate*` as
a first argument.
pipe_wrap: use Instantiate() method

Retrieve a new client object via PipeWrap::Instantiate(). This method
performs appropriate checks to make sure everything is as it should be.
vm: share security token between contexts

By default, each `v8::Context` has a different Security Token, which
prevents access to one context from another.

fix #7140
build: fix g++ 4.8 build, disable -Werror

Turn off -Werror when building V8, it hits -Werror=unused-local-typedefs
with g++ 4.8.  The warning itself is harmless so don't abort the build.

This was originally implemented in commit d2ab314e back in 2011 but the
build process has gone through a few iterations since then, that change
no longer works.
http: use defaultAgent.protocol in protocol check

Default to the `defaultAgent.protocol` when comparing the
user-specified `options.protocol` string. This is so that
`http.Agent` instances do not need to specify their own
`protocol` field, since we have the relevant information
already from the `defaultAgent`.

Note that the test case could be separately cherry-picked
to the `v0.10` branch, since it already passes correctly.

Fixes #7349.
Fixes the regression described in: http://git.io/2ds-WQ
doc: remove `agent.request()` call in example

The `Agent#request()` function was removed in
f3189ace6b5e31a874df421ac2f74da0e77cb14d, so don't
use it in the documentation example. The function
wasn't documented in the first place.
npm: upgrade to 1.4.6

* Documentation upgrades
* Fix glob bug which prevents proper README publishing
* node-gyp upgrade to 0.13
* Documentation updates
* Add --save-exact to save an exact dep (instead of a range)
* alias 't' to 'test'
src: seed V8's random number generator at startup

The default entropy source is /dev/urandom on UNIX platforms, which is
okay but we can do better by seeding it from OpenSSL's entropy pool.

On Windows we can certainly do better; on that platform, V8 seeds the
random number generator using only the current system time.

Fixes #6250.

NB: This is a back-port of commit 7ac2391 from the master branch that
for some reason never got back-ported to the v0.10 branch.

The default on UNIX platforms in v0.10 is different and arguably worse
than it is with master: if no entropy source is provided, V8 3.14 calls
srandom() with a xor of the PID and the current time in microseconds.

That means that on systems with a coarse system clock, the initial
state of the PRNG may be easily guessable.

The situation on Windows is even more dire because there the PRNG is
seeded with only the current time... in milliseconds.
src: ensure that openssl's PRNG is fully seeded

Ensure that OpenSSL has enough entropy (at least 256 bits) for its PRNG.

The entropy pool starts out empty and needs to fill up before the PRNG
can be used securely.

OpenSSL normally fills the pool automatically but not when someone
starts generating random numbers before the pool is full: in that case
OpenSSL keeps lowering the entropy estimate to thwart attackers trying
to guess the initial state of the PRNG.

When that happens, we wait until enough entropy is available, something
that normally should never take longer than a few milliseconds.

Fixes #7338.

build: windows signing should include timestamps

Previously the build artifacts did not include a signed timestamp, so
when the certificate expired the validation of the artifact would fail.
Now we sign against a timestamp server such that the artifact will
always be valid regardless of the disposition of the certificate.

Closes #7360 and #7059.
tls: force readable/writable to `true`

These are an old and deprecated properties that was used by previous
stream implementation, and are still in use in some user-land modules.

Prior to this commit, they were read from the underlying socket, which
may be non-readable/non-writable while connecting or while staying
uninitialized.

Force set them to `true`, just to make sure that there will be no
inconsistency.

fix #7152
tls: do not call SNICallback unless present

When asynchronously parsing ClientHello for session resumption -
SNICallback may not be set. Check if it is present before invoking
it.

http: better client "protocol not supported" error

Include the "expected protocol" in the Error message
string, which evaluates to "http:" for the `http`
core module, and "https:" for the `https` module.

Closes #7355.
configure: --v8-options option

Introduce a way to set some v8 flags at compile time, the values should
be separated by comma.
crypto: move `createCredentials` to tls

Move `createCredentials` to `tls` module and rename it to
`createSecureContext`. Make it use default values from `tls` module:
`DEFAULT_CIPHERS` and `DEFAULT_ECDH_CURVE`.
