Subject: SH-3280  Better init/shutdown functionality for llcorehttp by
 llappviewer Isolate llcorehttp initialization into a utility class
 (LLAppCoreHttp) that provides glue between app and library (sets up policies,
 handles notifications).  Introduce 'TextureFetchConcurrency' debug setting to
 provide some field control when absolutely necessary.
