Commit 93a44d5 ("src: fix deferred events not working with -e") defers
evaluation of the script to the next tick.
A side effect of that change is that 'beforeExit' listeners run before
the actual script. 'beforeExit' is emitted when the event loop is
empty but process.nextTick() does not ref the event loop.
Fix that by using setImmediate(). Because it is implemented in terms
of a uv_check_t handle, it interacts with the event loop properly.

Don't cache the exported values of fully uninitialized builtins.
This works by adding an additional `loading` flag that is only
active during initial loading of an internal module and checking
that either the module is fully loaded or is in that state before
using its cached value.
This has the effect that builtins modules which could not be loaded
(e.g. because compilation failed due to missing stack space) can be
loaded at a later point.

In several places throughout the code we write directly to stderr
to report warnings (deprecation, possible eventemitter memory leak).
The current design of simply dumping the text to stderr is less
than ideal. This PR introduces a new "process warnings" mechanism
that emits 'warning' events on the global process object. These are
invoked with a `warning` argument whose value is an Error object.
By default, these warnings will be printed to stderr. This can be
suppressed using the `--no-warnings` and `--no-deprecation` command
line flags. For warnings, the 'warning' event will still be emitted
by the process, allowing applications to handle the warnings in custom
ways. The existing `--no-deprecation` flag will continue to supress
all deprecation output generated by the core lib.
The `--trace-warnings` command line flag will tell Node.js to print
the full stack trace of warnings as part of the default handling.
The existing `--no-deprecation`, `--throw-deprecation` and
`--trace-deprecation` flags continue to work as they currently do,
but the exact output of the warning message is modified to occur
on process.nextTick().
The stack trace for the warnings and deprecations preserve and point
to the correct call site.
A new `process.emitWarning()` API is provided to permit userland
to emit warnings and deprecations using the same consistent
mechanism.
Test cases and documentation are included.
