dgram: fix abort when getting `fd` of closed dgram

v8's `messages.js` file's `CallSiteGetMethodName` is running through all
object properties and getter to figure out method name of function that
appears in stack trace. This run-through will also read `fd` property of
`UDPWrap` instance's javascript object, making `UNWRAP()` fail.

As a simple alternative to the test case above, one could just keep
reference to the dgram handle and try accessing `handle.fd` after it has
been fully closed.

fix #6536
net: fix `new net.Socket` documentation

`Socket` no longer accepts `type` option, and also accepts `readable`,
`writable` options.

events: do not accept NaN in setMaxListeners
crypto: `randomBytes` is non-blocking

Add NOTE section in documentation, mentioning that `randomBytes` won't
block when entropy sources are drained.

uv: upgrade to v0.11.15
child_process: deliver ENOENT on nextTick

After the uv upgrade, uv_spawn will now fail faster for certain
failures like ENOENT. However, our tests and other people may be
depending on that error being passed to the callback instead of a
throw.

node: allow nextTick infinite recursion

Removing the depth counter while processing the nextTickQueue made it
possible to run out of memory if in an infinite recursive loop using
nextTick(). There was also an edge case where too many callbacks were
pushed onto the nextTickQueue, while not actually being recursive.

This is being done to prevent possible cryptic FATAL ERROR messages from
popping up, and issues being posted about them.
