src: add --heapsnapshot-near-heap-limit option
...
This patch adds a --heapsnapshot-near-heap-limit CLI option
that takes heap snapshots when the V8 heap is approaching
the heap size limit. It will try to write the snapshots
to disk before the program crashes due to OOM.

worker,src: display remaining handles if uv_loop_close fails

Right now, we crash the process if there are handles remaining
on the event loop when we exit (except for the main thread).
This does not provide a lot of information about causes, though;
in particular, we don’t show which handles are pending and
who own them.
This patch adds debug output to these cases to help with the
situation.

src: implement debug output utilities
...
Implement utilities for easier debugging of Node.js core code,
inspired by the HTTP/2 debugging code. Debugging is, however,
implemented at runtime rather than at compile time, controlled
through a new `NODE_DEBUG_NATIVE=categories` environment variable.
The runtime overhead in the debugging-disabled case amounts to
1 well-cachable one-byte read per debug call.
