Helper to track which spans never get closed.

Sourcetype unclosed_spans = {

}

val track : 
  ?on_lingering_spans:[ `Out of out_channel | `Call of unclosed_spans -> unit ] ->
  Trace_core.Collector.t ->
  Trace_core.Collector.t

Modify the enter/exit span functions to track the set of spans that are open, and warn at the end if some are not closed.

implementation notes: for now this uses a regular Hashtbl protected by a mutex, so runtime overhead isn't trivial.
