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.

The command line flag `--debug-brk` was ignored when the `-e` flag was
also present. This change allows the flags to both be honored when they
are used in a single command line.

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
included. This is derived from the implementation in Blink.
v8-inspector support can be disabled by the --without-inspector
configure flag.

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.

Minor clean up. There are still some places in core that use
the legacy __defineGetter__ syntax. This updates most of those.

Minor cleanup of how --debug-brk works:
* We no longer need to use command line flags to expose the debug
object.
* Do not depend on the existence of global.v8debug as a mechanism to
determine if --debug-brk was specified.
* We no longer need to set a dummy listener with --debug-brk.

Make the builtin libraries available for the `--eval` and
`--print` CLI options, using the same mechanism that the
REPL uses.
This renders workarounds like `node -e 'require("fs").doStuff()'`
unnecessary.
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.

This commit improves module loading performance by at least ~25-35%
in the module-loader benchmarks.
Some optimization strategies include:
* Try-finally/try-catch isolation
* Replacing regular expressions with manual parsing
* Avoiding unnecessary string and array creation
* Avoiding constant recompilation of anonymous functions and
function definitions within functions

Introduce `--no-browser-globals` configure flag. With this flag set, following
globals won't be exported:
- `setTimeout`, `clearTimeout`, `setInterval`, `clearInterval`,
`setImmediate`, `clearImmediate`
- `console`
These are provided by the DOM implementation in browser, so the
`--no-browser-globals` flag may be helpful when embedding node.js within
chromium/webkit.

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.
