mmlr + bonefish:

* Move struct tracing_stack_trace to tracing.h header.
* Add tracing_find_caller_in_stack_trace(). Helper function to get the
  first return address of a stack trace that is not in one of the given
  address ranges.
* Add AbstractTracingEntryWithStackTrace::StackTrace() getter.
* Add tracing_is_entry_valid(). Checks, based on the additionally given
  time, whether a tracing entry is (probably) still in the tracing
  buffer.
