When getaddrinfo linked-list results contain entries other than AF_INET
and AF_INET6, the resulting v8::Array will contain undefined values.
That's because initialization of v8::Array pre-allocates entries for all
linked-list nodes, but not all of them will be in the final results.
This commit ensures that the array only contains valid results.

New instances of AsyncWrap are automatically assigned a unique id. The
value will be used in future commits to communicate additional

While the largest value we can reliably communicate to JS is 2^53, even

for 28.5 years.

Before this commit, sending a SIGUSR1 at program exit could trigger a
hard to reproduce race condition where `v8::Debug::DebugBreak(isolate)`
got called when the isolate was in the process of being torn down.
A similar race condition is in theory possible when sending signals
to two threads simultaneously but I haven't been able to reproduce
that myself (and I tried, oh how I tried.)
This commit fixes the race condition by turning `node_isolate` into
a `std::atomic` and using it as an ad hoc synchronization primitive
in places where that is necessary.
A bare minimum std::atomic polyfill is added for OS X because Apple
wouldn't be Apple if things just worked out of the box.

Previous logic didn't allow parent to propagate to the init callback
properly. The fix now allows the init callback to be called and receive
the parent if:
- async wrap callbacks are enabled and parent exists
- the init callback has been called on the parent and an init callback
exists then it will be called regardless of whether async wrap
callbacks are disabled.
Change the init/pre/post callback checks to see if it has been properly
set. This allows removal of the Environment "using_asyncwrap" variable.
