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.

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.

deps: apply floating patch to v8

Original commit message below:

fix FunctionCallbackInfo ambiguity

- when compiling tools that embed v8 with g++ FunctionCallbackInfo is currently ambigous
- more info: https://github.com/joyent/node/issues/7337
- original patch is here: https://codereview.appspot.com/78770045/

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`.

fix #7249
fs: improve performance of all stat functions

By building the fs.Stats object in JS, which is returned by all fs stat
functions, calls to v8::Object::Set() are removed. This also includes
creating all associated Date objects in JS, rather than using
v8::Date::New(). Both these changes have significant performance gains.

Note that the returned value from fs.stat changes slightly for non-POSIX
systems. Whereas before the stats object would be missing blocks and
blksize keys, it now has these keys with undefined as the value.

configure: make --v8-options switch more robust

Improve on commit b55c9d6 by not requiring that switches are comma
separated.  This commit makes `./configure --v8-options="--foo --bar"`
work and takes special care to properly escape quotes in the options
string.
v8: upgrade to 3.24.35.22
test: make test-smalloc endian aware

The test/simple/test-smalloc.js has an implicit assumption
of the byte order of the data stored for Double and Uint32
values. On a big endian platform this test fails without
these patches.

Use os.endianness() to detect the endian of the platform
and use it to gate the static value used for comparison.
deps: upgrade v8 to 3.25.30
deps: fix up v8 postmortem codegen

Fix up overzealous parses, strip whitespace from class and field names.
src: fix up after v8 upgrade

The two biggest changes are that v8::Script::New() has been removed and
that a v8::Script object now has to be explicitly bound to a context if
you want to run it from another context.

We can accommodate both changes without breaking the vm module's public
API or even the internal JS API.
buffer: improve {read,write}{U}Int* methods

Increase the performance and simplify the logic of Buffer#write{U}Int*
and Buffer#read{U}Int* methods by placing the byte manipulation code
directly inline.

Also improve the speed of buffer-write benchmarks by creating a new
call directly to each method by using Function() instead of calling by
buff[fn].

node: add signature to SET_PROTOTYPE_METHOD

This prevents segfaults when a native method is reassigned to a
different object (which corrupts args.This()).  When unwrapping,
clients should use args.Holder() instead of args.This().

Closes #6690.
