This patch adds a command line option (-r/--require) that allows one
to provide modules on the command line that will be 'required' during
node startup. This can be useful for debugging, tracing, memory leak
analysis etc. to be preloaded without explicit changes to the user

This patch allows 'vendors' (such a cloud host) to inject functionality

If run with --abort-on-uncaught-exception, V8 will abort the process
whenever it does not see a JS-installed CatchClause in the stack. C++
TryCatch clauses are ignored. Domains work by setting a FatalException
handler which is ignored when running in abort mode.
This patch modifies MakeCallback to call its target function through a
JS function that installs a CatchClause and manually calls _fatalException
on error, if the process is both using domains and is in abort mode.

Call a user-defined callback at specific points in the lifetime of an
asynchronous event. Which are on instantiation, just before/after the
callback has been run.
**If any of these callbacks throws an exception, there is no forgiveness
or recovery. A message will be displayed and a core file dumped.**
Currently these only tie into AsyncWrap, meaning no call to a hook
callback will be made for timers or process.nextTick() events. Though
those will be added in a future commit.
Here are a few notes on how to make the hooks work:
- The "this" of all event hook callbacks is the request object.
- The zero field (kCallInitHook) of the flags object passed to
setupHooks() must be set != 0 before the init callback will be called.
- kCallInitHook only affects the calling of the init callback. If the
request object has been run through the create callback it will always
run the before/after callbacks. Regardless of kCallInitHook.
- In the init callback the property "_asyncQueue" must be attached to
the request object. e.g.
function initHook() {
this._asyncQueue = {};
}
- DO NOT inspect the properties of the object in the init callback.
Since the object is in the middle of being instantiated there are some
cases when a getter is not complete, and doing so will cause Node to
crash.
