Most of these changes address removing unnecessary type erasures
Several related to the change to
std::thread;std::threadis polymorphic while our preceding threading library was not. When we converted, we never removed the type erasure the prior library requiredThe other major change is to switch
RunQueryCoreLoopto take astd::functioninstead of a bare function pointer and a type-erased argument list. This makes the functors forRunQueryCoreLoopmore transparent and easier to understand. Hopefully gcc 10 will acceptstd::placeholders. :)
