All compile time warnings about using deprecated APIs have been
suppressed by updating node's API. Though there are still many function
calls that can accept Isolate, and still need to be updated.

node_isolate had to be added as an extern variable in node.h and
node_object_wrap.h

Also a couple small fixes for Error handling.

Before v8 3.16.6 the error stack message was lazily written when it was
needed, which allowed you to change the message after instantiation.
Then the stack would be written with the new message the first time it
was accessed. Though that has changed. Now it creates the stack message
on instantiation. So setting a different message afterwards won't be
displayed.

This is not a complete fix for the problem. Getting error without any
message isn't very useful.

This reverts commit f8519e10b823f576ddd0efa76ab425f0598b1223.

Recent update to V8 fixes the problem where it incorrectly reports the
line number as 0 for thrown RangeErrors.

So instead of:

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^

You will now see:

path/to/foo.js:1
throw new Error('bar');
      ^

This is a sub-set of isaacs patch here:

https://github.com/joyent/node/issues/3235

The difference is that this patch purely adresses the exception output,
but does not try to make any behavior changes / improvements.

This patch now reports the proper throw call site for exceptions
triggered within process.nextTick. So instead of this:

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^

You will now see:

mydir/myscript.js:15
  throw new Error('My Error');
          ^

From my testing this patch causes no performance regressions, but does
greatly simplify processing the nextTickQueue.

V8 3.4.12.1 changed exception log format.

3.14.10:
node.js:189
        throw e; // process.nextTick error, or 'error' event on first tick
        ^

3.4.12.1:
node.js:189
        throw e; // process.nextTick error, or 'error' event on first tick
              ^

The caret was moved.
