node: do not ever close stdio

Even if stdio streams are opened as file streams, we should not ever try
to close them. This could be accomplished by passing `autoClose: false`
in options on their creation.
deps: backport 883637bd from latest v8

Original commit message:

  VS2013 contains a number of improvements, most notably the addition
  of all C99 math functions.

  I'm a little bit concerned about the change I had to make in
  cpu-profiler.cc, but I spent quite a bit of time looking at it and was
  unable to figure out any rational explanation for the warning. It's
  possible it's spurious. Since it seems like a useful warning in
  general   though, I chose not to disable globally at the gyp level.

  I do think someone with expertise here should probably try to
  determine if this is a legitimate warning.

NOTE: Path applied without `cpu-profiler.cc` changes because in our
version it was looking totally different.
dtrace: fix arguments warning

Add enough arguments to `NODE_NET_SOCKET_READ()` and
`NODE_NET_SOCKET_WRITE()` stubs.
zlib: add sync versions for convenience methods
doc: add an example about multiple extensions

`path.extname` returns only the last extension
debugger: remove unused definition `currentSource`

Client's property `currentSource` has no use throughout the project.
tls: fix crash in SNICallback

`tls_wrap.cc` was crashing in an `Unwrap` call, when non
`SecureContext` object was passed to it. Check that the passed object
is a `SecureContext` instance before unwrapping it.

fix #7008
zlib: separate sync/async methods
crypto: update root certificates

Update the list of root certificates in src/node_root_certs.h with
tools/mk-ca-bundle.pl and update src/node_crypto.cc to make use of
the new format.

Fixes #6013.

openssl: fix keypress requirement in apps on win32

Re-applying commit 153784b3489e2feb9d93a3a5eee5a4aa34f74e39, which
was overwritten by the update to openssl 1.0.1f.

doc: fix references to error keyword

References for err.signal and err.code should be error.signal and
error.code.

Fixes joyent/node#6862
test: fix test-tcp-wrap-listen

If the call to writeBuffer completes asynchronously, we need to have
an oncomplete callback on the request object no matter what. The
writeQueueSize seems irrelvant to that regard.

Note that on Windows writeBuffer always completes asynchronously.

contextify: handle infinite recursion errors

Try to be consistent with v0.10 and emit "Maximum call stack size
reached", even if it happens when allocating context or doing other
stuff.

fix #7045
tls: more session configuration options, methods

Introduce `ticketKeys` server option, `session` client option,
`getSession()` and `getTLSTicket()` methods.

fix #7032
src: update MakeCallback() function prototype

Make it possible to invoke MakeCallback() on a v8::Value but only for
the variant that takes a v8::Function as the thing to call.

The const char* and v8::String variants still require a v8::Object
because the function to call is looked up as a property on the receiver,
but that only works when the receiver is an object, not a primitive.
src: fix MakeCallback() handle leak

Create a new HandleScope before looking up the object context with
v8::Object::CreationContext(), else we leak the Local<Context> into
the current HandleScope.

That's relatively harmless unless the HandleScope is long-lived and
MakeCallback() is called a lot.  In a scenario like that, we may end
up leaking a lot of memory.

What is unfortunate about this change is that we're trying hard to
eradicate the node_isolate global.  Longer term, we will probably have
to change the MakeCallback() prototype to one that requires an explicit
v8::Isolate* argument.
src: add tracing.v8.on('gc') statistics hooks

Add a new 'tracing' module with a v8 property that lets the user
register listeners for gc events.  The listeners are invoked after
every garbage collection cycle with 'before' and 'after' statistics.
Useful for monitoring tools that want to keep track of memory usage.
