Previously: * applications were using isc_app as the base unit for running the application and signal handling. * networking was handled in the netmgr layer, which would start a number of threads, each with a uv_loop event loop. * task/event handling was done in the isc_task unit, which used netmgr event loops to run the isc_event calls. In this refactoring: * the network manager now uses isc_loop instead of maintaining its own worker threads and event loops. * the taskmgr that manages isc_task instances now also uses isc_loopmgr, and every isc_task runs on a specific isc_loop bound to the specific thread. * applications have been updated as necessary to use the new API. * new ISC_LOOP_TEST macros have been added to enable unit tests to run isc_loop event loops. unit tests have been updated to use this where needed.
