Since fs.watch returns an event emitter where the change event is exactly
the same as the listener callback, the argument should be required

Rather than omitting them.

A build failure was introduced on c9676c91
in SmartOS systems.  This makes it build properly.

This reverts commit f8519e10.

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

http.get() now accepts either a URL (as a string) or an options object.

request.end() would sometimes try to write a zero-length buffer to the socket.
Don't do that, it triggers an unnecessary EPIPE when the other end has closed
the connection.

Fixes #3257.

Before this commit, process._getActiveHandles() returned a list of internal
handles. Now, it returns the user objects that handles are attached to.

For example, a tcp_wrap handle will now return its parent net.Socket object.

It works for all handle types except timers because timer handles are shared
across multiple user objects.

* process._getActiveHandles() returns a list containing all active handles
  (timers, sockets, etc.) that have not been unref'd.

* process._getActiveRequests() returns a list of active requests (in-flight
  actions like connecting to a remote host, writing data to a socket, etc.).

Share persistent strings process_symbol and domain_symbol across compilation
units. Avoids redefinition errors when src/node.cc includes src/req_wrap.h.
