Add counters for GC-related info #1168

Open wingo opened 6 years ago

wingo commented 6 years ago

We should have counters with time-travel info for:

Number of traces emitted.
GCState total and threshold (https://github.com/Igalia/snabb/blob/lwaftr/lib/luajit/src/lj_obj.h#L573)
Number of GC cycles (could increment in lj_gc.c:atomic())

This would allow us to know if packet losses correspond to traces being emitted, or to GC events.
