Anna Henningsen aa2304b8d5 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.

Anna Henningsen bd85844c4e 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.
