a235ccd168 src,test: debug is now an alias for inspect
`node debug` is now an alias of `node inspect`. This is intended to be
a minimal change – it does not get rid of the the debugger code. That
can be done in a follow-on.

9ff7ed23cd lib: fix event race condition with -e
Commit c5b07d4 ("lib: fix beforeExit not working with -e") runs the
to-be-evaluated code at a later time than before because it switches
from `process.nextTick()` to `setImmediate()`.

It affects `-e 'process.on("message", ...)'` because there is now a
larger time gap between startup and attaching the event listener,
increasing the chances of missing early messages.  I'm reasonably
sure `process.nextTick()` was also susceptible to that, only less
pronounced.

Avoid the problem altogether by evaluating the code synchronously.
Harmonizes the logic with `Module.runMain()` from lib/module.js
which also calls `process._tickCallback()` afterwards.

c5b07d4ec6 lib: fix beforeExit not working with -e
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.

f6070a1a02 deps: v8_inspector: console support
When node is running with --inspect flag, default console.log,
console.warn and other methods call inspector console methods in
addition to current behaviour (dump formatted message to stderr and
stdout). Inspector console methods forward message to DevTools and
show up in DevTools Console with DevTools formatters. Inspector
console methods not present on Node console will be added into it.

Only own methods on global.console object will be changed while in a
debugging session. User are still able to redefine it, use
console.Console or change original methods on Console.prototype.

This change introduces experimental v8-inspector support. This brings
the DevTools debug protocol allowing Node.js to be debugged with
Chrome DevTools native, or through other debuggers supporting that
protocol.

Partial WebSocket support, to the extent required by DevTools, is

v8-inspector support can be disabled by the --without-inspector

module: don't cache uninitialized builtins
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.

This renders workarounds like `node -e 'require("fs").doStuff()'`

As part of this, the list of builtin modules and the code for
adding the corresponding properties to the target context is moved
to `internal/module.js`, and the previously missing `repl` entry
is added.

c6656db352 process: add 'warning' event and process.emitWarning()
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.
