The TryCatch was not being checked after calling the unload asyncQueue
callback in AsyncWrap::MakeCallback.

Before this commit, passing --debugger and other V8 debug switches to
node.js made node print a usage message and exit.

Rewrite the debug argument parser so it only consumes switches that we
understand and pass everything else as-is to V8.

A side effect of this change is that switches like --debugger_agent and
--debugger_port now work.  That kind of obsoletes our debugger switches
because they implement pretty much the same functionality but let's
leave them in for now for the sake of convenience and backwards
compatibility.

Fixes #6526.

In many cases values expected to be unsigned were converted to a signed
integer.

Also include some small code cleanup.

Fixes #6490

Buffer#write() was showing the deprecation warning when only
buf.write('string') was passed. This is incorrect since the encoding is
always optional.

Argument order should follow:
  Buffer#write(string[, offset[, length]][, encoding])

(yeah, not confusing at all)

Node.js.  It's not just for SF hipsters anymore.

This commit introduces some long lines but it's HTML so it's okay.

Add HasExternalData API to check if Object has externally allocated
memory, and accompanying tests.

Emitting an event within a `EventEmitter#once` callback of the same
event name will cause subsequent `EventEmitter#once` listeners of the
same name to be called multiple times.

    var emitter = new EventEmitter();

    emitter.once('e', function() {
      emitter.emit('e');
      console.log(1);
    });

    emitter.once('e', function() {
      console.log(2);
    });

    emitter.emit('e');

    // Output
    // 2
    // 1
    // 2

Fix the issue, by calling the listener method only if it was not
already called.

BaseObject is a class that just handles the Persistent handle attached
to the class instance.

This also removed WeakObject. Reordering the inheritance chain helps
prevent unneeded calls on instances that don't call MakeCallback.

They didn't need to be defined in the body of the constructor.

Enter the context explicitly, don't rely on the fact that there is a
Context::Scope a few stack frames below because it may be gone someday

env->context() may or may not create a new Local.  It currently does
not but don't depend on that behavior, create a HandleScope first.

Don't depend on any HandleScope objects that may or may not have been
created in src/stream_wrap.cc, create them explicitly.

Make it more difficult to accidentally leak handles by removing the
top-level HandleScope.  Now if there's no valid HandleScope now, V8
will complain and, in debug builds, abort.

Fixes a 4 byte leak on handles closing. AKA The Walmart leak.

MakeCallback doesn't have a HandleScope. That means the callers scope
will retain ownership of created handles from MakeCallback and related.
There is by default a wrapping HandleScope before uv_run, if the caller
doesn't have a HandleScope on the stack the global will take ownership
which won't be reaped until the uv loop exits.

If a uv callback is fired, and there is no enclosing HandleScope in the
cb, you will appear to leak 4-bytes for every invocation. Take heed.

`timezone` variable contains the difference, in seconds, between UTC and
local standard time (see `man 3 localtime` on Solaris).

Call to `tzset` is required to apply contents of `TZ` variable to
`timezone` variable.

BUG=v8:2064

Review URL: https://chromiumcodereview.appspot.com/10967066
Patch from Maciej Małecki <me@mmalecki.com>.

This is a back-port of upstream commit r12802 and a forward port of
commit 9fa953d3 from the v0.8 branch.  V8 3.22 in the master branch
contains the patch so no further forward-porting is necessary.

Fix invalid `hasOwnProperty` function usage.

For example, before in the REPL:

```
> Ar<Tab>
Array

Array        ArrayBuffer
```

Now:

```
> Ar<Tab>
Array

ArrayBuffer
```

Fixes #6255.
Closes #6498.

Create a HandleScope before calling the Environment::GetCurrent() that
takes a v8::Isolate* as an argument because it creates a handle with
the call to v8::Isolate::CurrentContext().

MakeCallback can only be called from a valid v8::HandleScope.

Fixed #6487

This commit removes the simple/test-event-emitter-memory-leak test for
being unreliable with the new garbage collector: the memory pressure
exerted by the test case is too low for the garbage collector to kick
in.  It can be made to work again by limiting the heap size with the
--max_old_space_size=x flag but that won't be very reliable across
platforms and architectures.

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.

This is a file from the NSS project containing root certificate data.
It can be downloaded from:

  https://mxr.mozilla.org/mozilla/source/security/nss/lib/ckfw/builtins/certdata.txt?raw=1

Once downloaded, running `perl tools/mk-ca-bundle.pl` will update
src/node_root_certs.h.  Commit, rebuild and go.

Remove unneeded functionality and tweak the generated output so we
can #include it in C++ source code.
