Subject: SH-4312  Configuration data between viewer and llcorehttp is clumsy.
 Much improved.  Unified the global and class options into a single option
 list.  Implemented static and dynamic setting paths as much as possible. 
 Dynamic path does require packet/RPC but otherwise there's near unification. 
 Dynamic modes can't get values back yet due to the response/notifier scheme
 but this doesn't bother me. Flatten global and class options into simpler
 struct-like entities. Setter/getter available on these when needed (external
 APIs) but code can otherwise fiddle directly when it knows what to do.  Much
 duplicated options/state removed from HttpPolicy.  Comments cleaned up. 
 Threads better described and consistently mentioned in API docs.  Integration
 test extended for 503 responses with Reply-After headers.
