test: fixes due to new cluster api.

- changed worker `death` to `exit`.
- corrected argument type expected by worker `exit` handler.

test: more tests of cluster.worker death

cluster: fixed arguments on worker 'exit' event

worker 'exit' event now emits arguments consistent with the
corresponding event in child_process module.

The crashes in debug mode after adding Locker are *not* caused by
Locker. Locker is merely exposing issues that already existed. Some of
these issues have since been fixed in 70635753.

This reverts commit 40718153.
This reapplies commit 9a6012ed.

Move parsers.free(parser) to a single function, which also
nulls all of the various references we hang on them.

Also, move the parser.on* methods out of the closure, so that
there's one shared definition of each, instead of re-defining
for each parser in a spot where they can close over references
to other request-specific objects.

Regarding #3199 and #3179 and issues seen in production.
Hopefully this fixes them.

* Upgrade npm to 1.1.21

* uv: Add support for EROFS errors (Ben Noordhuis, Maciej Małecki)

* uv: Add support for EIO and ENOSPC errors (Fedor Indutny)

* windows: Add support for EXDEV errors (Bert Belder)

* http: Fix client memory leaks (isaacs, Vincent Voyer)

* fs: fix file descriptor leak in sync functions (Ben Noordhuis)

* fs: fix ReadStream / WriteStream double close bug (Ben Noordhuis)

This way it doesn't die when running as root.

Fixes #3196.

Lets native addons register exit hooks that run after the event loop has quit
but before the VM is killed.

Fixes #3147.

Fixes #3202. This is a back-port of commit 4e290e48.

Fixes #3202.

* Calling fs.ReadStream.destroy() or fs.WriteStream.destroy() twice would close
  the file descriptor twice. That's bad because the file descriptor may have
  been repurposed in the mean time.

* A bad value check in fs.ReadStream.prototype.destroy() would prevent a stream
  created with fs.createReadStream({fd:0}) from getting closed.

It makes mksnapshot die with a segmentation fault on sunos with gcc 4.5.2.

This reverts commit c21c51a6.
