worker,src: display remaining handles if `uv_loop_close` fails

2018-06-13T10:23:36+00:00

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.

Use a single file, and a single interface, for inspecting
symbols in the current process for debugging.

src: implement debug output utilities

2018-05-31T07:54:48+00:00

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.
