Add (default off) support for dying on malloc in RT code
Our malloc is not realtime. We shouldn't be using it in RT code. To
enforce this, add a hook into tcmalloc to LOG_RAW(FATAL) whenever an
application tries to allocate memory inside code running at the RT
priority level.
We have code in our drivetrain code which is allocating memory still
when realtime. That prevents us from enabling it yet.
