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

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.

This fixes the additional issues brought up in #3179.

Fixes #3196.

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

* 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.

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